Kavli IPMU Annual Report 20131

Foreword
It is a good time to reflect on the first seven years of our institute. The Kavli Institute for the Physics and Mathematics of the Universe (Kavli IPMU) was founded seven years ago on October 1,
2007. We proposed to address five basic questions about the Universe, how it began, what it ismade of, what its fate is, what its fundamental laws are, and why we exist in it. We do so by combining mathematics, physics, and astronomy, employing accelerator-based experiments, underground experiments, and observations at telescopes. This Institute literally started from scratch,
but now has grown to a size of about 150 people on site including graduate students and support
staff.
Overall, I believe the Institute came out to be exactly as proposed. Our unique building allows
mathematicians, physicists and astronomers to be under the same roof, sharing seminars and thedaily teatime. Interdisciplinary discussions have become a commonplace. The Institute is highlyinternational; more than a half of the members are not Japanese nationals. Every member was
hired anew, and the quality of the hires is clear; about 90% of the postdocs have been offered positions at other excellent institutions after their term at Kavli IPMU, and more than a third of themare on faculty positions by now. Our citation counts are similar to other world-leading research
institutions. Thanks to several high profile papers and high international visibility, our members
are invited to major conferences as keynote or summary speakers. We advertise positions internationally and attract nearly a thousand applications each year.

Hitoshi Murayama
Director

Many papers were written based on mutual inspiration of mathematicians and physicists. Key “interpreters” to overcome the language barrier between mathematicians and physicists played criticalroles to make it possible. This is crucial to address the question “what are the fundamental laws?”
The large projects proposed in the original proposal are producing fruits. The direct dark matter
detection experiment XMASS was built and produced world best limits on some candidates. It isaddressing the question “what is the Universe made of.” The KamLAND-Zen effort produced theworld best limit on neutrinoless double beta decay (this result was published in February, 2013,namely, in FY2012). Hyper Suprime-Cam (HSC) was designed, built, commissioned, and the
300-night survey was approved on the Subaru telescope, one of the largest in the world. Data fromthe initial few nights are being analyzed. Combined with the theoretical research by our members,
they address the question “why do we exist.”
We proposed Prime Focus Spectrograph (PFS) in 2009, which is now under construction. The
combination of imaging survey using HSC and spectroscopic survey using PFS on the same telescope promises to be a world-leading observational program, looking into “the fate of the Universe” a trillion years from now. We are now proposing LiteBIRD satellite experiment to look forthe evidence for the cosmic inflation, to address the question “how did the Universe begin?” looking back to the era when the Universe we see today was much smaller than the size of an atomic
nucleus, only 10 –37 seconds from the Beginning.
All of this progress will be lost if the institute cannot secure funding. Fortunately thanks to thestrong leadership of President Junichi Hamada, the University promised to sustain our institute atsome level. In addition, the Kavli Foundation donated endowment to give us flexibility. We now
know we will not disappear from the map. We are looking into an even brighter future!

Introduction

FY 2013 marks the seventh year of the Kavli IPMU since it launched as IPMU, the Institute for the Physics and Mathematics of the Universe, on October 1, 2007. In these seven years, the Kavli IPMU has grownsignificantly. As seen from the annual transition statistics shown at the end of this section, the Kavli IPMU
had 245 researchers (including affiliated members) and 40 administrative and research support staff members as of March 31, 2014 (the end of FY 2013). As one of the initial five WPI (World Premier Institutes Initiative) institutes founded at the same time, globalization has been one of the objectives of the Kavli IPMU.
The proportion of the number of foreign researchers is an appropriate index to represent this effort, and it is
40% as of the end of FY 2013.
As a research institute addressing the fundamental questions of the Universe, the most important objectiveis scientific accomplishment. In these seven years, the number of papers published by Kavli IPMU researchers in refereed journals yearly has shown steady growth, as shown by the annual transition statistics. Manyof these papers have been published in journals having a high impact factor. Also, many of these papers
have high citation statistics. Some selected research highlights achieved in FY 2013 are given in Section 5.
Although most of the scientific achievements in the early years of the Kavli IPMU were theoretical, a noteworthy feature in FY 2013 is that results have been reported from experimental and observational projects,
such as XMASS, which generally need a long lead time. Another notable feature is that significant achievements in mathematics have been reported by mathematicians at the Kavli IPMU. Generally, the time scaleof research in mathematics (for instance, the time needed from submission of a paper to publication) is longer than that in physics and astronomy. It seems that seven years since its launch, research in mathematics
at the Kavli IPMU is now in a steady state of flourishing.
Experimental / observational projects that the Kavli IPMU has been promoting also show steady progress.
A Kavli IPMU team shares the responsibility for fabricating a silicon vertex detector for the Belle 2 experiment, and this task has advanced well. Since the engineering first light of the Hyper Suprime-Cam (HSC),
the new-generation prime-focus camera of the Subaru telescope, in August 2012 (see the Kavli IPMU Annual Report 2012), the HSC international collaboration has been conducting a series of performance test
observations while also working on the data analysis software under the initiatives of researchers at Princeton University, Kavli IPMU, and NAOJ. The beautiful image of the Andromeda Galaxy (M31) on the cover
page of this Annual Report is one of the first images processed with this data analysis software.
HSC has been developed as one of the two subprojects of the SuMIRe (Subaru Measurement of Images
and Redshifts) Project, which is supported by FIRST (The Funding Program for World-Leading Innovative
R&D on Science and Technology), and led by Kavli IPMU Director Hitoshi Murayama as a core researcher.
Another component of SuMIRe is a multi-object spectrograph, the Prime Focus Spectrograph (PFS), which
is currently in the development and instrumentation process. The PFS will share the wide field corrector of
HSC, and there are plans to make a spectroscopic observation for a few million galaxies selected from thegalaxy catalog provided by the HSC survey. The combination of imaging and spectroscopic galaxy data forthe same region of the sky will be an extremely powerful tool for studying the mysterious nature of dark
matter and dark energy.
The Kavli IPMU has concluded a number of cooperative research agreements with domestic as well as
overseas institutions. In December 2013, the Kavli IPMU signed a new collaboration agreement with
iTHES (Interdisciplinary Theoretical Science team) of RIKEN (the Institute of Physical and Chemical Re-

4

Kavli IPMU Annual Report 2013search). iTHES is a new group launched in 2013 at RIKEN with Chief Scientist Tetsuo Hatsuda designatedas Director, aiming at interdisciplinary collaboration in the theoretical sciences in different fields such as
physics, material science, and biology. This is the beginning of a collaboration between the Kavli IPMU
and iTHES for the development of the theoretical sciences. We note that Dr. Hatsuda is also a Visiting Senior Scientist at the Kavli IPMU since October 2010.
As usual, many distinguished guests visited the Kavli IPMU in FY 2013. On November 19–20, 2013, Fabiola Gianotti, former spokesperson of the ATLAS experiment that discovered the Higgs boson at CERN;
on January 24–25, 2014, Lisa Randall, Professor at Harvard University; on March 26–April 3, 2014, Peter
Goddard, former Director of the Institute for Advanced Study; and many other distinguished scientists
visited the Kavli IPMU. Fabiola Gianotti and Lisa Randall also gave public lectures at venues in Tokyo. On
November 20, 2013, Minister of State for Science and Technology Policy Ichita Yamamoto visited the Kavli
IPMU and heard about the SuMIRe project from Director Murayama and other researchers. He also heard
progress reports from SuMIRe collaborators at Princeton University and NASA’s Jet Propulsion Laboratory
via videoconference. Mr. Yamamoto also observed activities at the Kavli IPMU, such as Fabiola Gianotti’s
seminar, which was held on that day, laboratory work for an experimental apparatus, and joining a tea time
discussion for researchers.
In FY 2013 also, the Kavli IPMU contributed to science policy, public understanding of science, promotionof science education, etc. On December 17, 2013, Director Murayama was invited to the 116th session of theCouncil for Science and Technology Policy (CSTP) held at the Prime Minister’s official residence to give a
presentation in the latter half of the session in which “The Trend of Science & Technology” was discussed.
In his presentation, he explained the Kavli IPMU’s research looking into the origin and fate of the Universe. A three-day winter science camp for high school students, “Open the Door to the Universe” was heldat the Kavli IPMU from December 25 to 27, 2013, and twenty students selected among applicants from allover Japan took part. This was the third science camp held at the Kavli IPMU. The science camp is one ofthe projects supported by JST (Japan S&T Agency), providing hands-on experience to high school students.
The Kavli IPMU also planned, hosted, or joined a number of outreach events; see Section 13.
A working group comprised of twelve Kavli IPMU Administrative Division staff members has received the2013 President’s Award for Operational Improvement. (The group has actually received the highest award
with ¥1M support for overseas study tours as a supplementary prize.) The award has been given in recognition of the group’s creation of a safety training video in English and for construction of an online system totest for the training contents. This resulted in prompt, comprehensive safety training for all newly arriving
foreign researchers and a reduction of the administrative burden for such training. This kind of system is
expected to be adopted university-wide, thus contributing to the further globalization of the University ofTokyo. The award was presented by President of the University of Tokyo Junichi Hamada at an awards ceremony held on December 19, 2013 at the Ito Hall on the University of Tokyo’s Hongo campus. Representing
the working group, Rieko Tamura received a testimonial.
Finally, we should mention that Fred Kavli, Founder and Chairman of The Kavli Foundation passed away
on November 21, 2013 at the age of 86. In 2012, the IPMU joined the Kavli family as the first Kavli Institute in Japan and the 16th in the world, and renamed it the Kavli IPMU, following an endowment from The
Kavli Foundation. We will never forget Fred Kavli’s generous support to the Kavli IPMU.

Deputy Directors
Hiroaki Aihara
Yoichiro Suzuki

The Director is appointed by the President of the University of Tokyo and reports directly
to his office. The Director proposes to hire the Principal Investigators to the President. For
other hiring of research staff and administrative staff, he has a complete authority. He is
also solely responsible for making all other decisions. He is assisted by the two Deputy
Directors, the Associate Director, and the Administrative Director. They constitute the
Executive Board (EB) and regularly meet to ensure smooth operation of the Institute. The
EB has direct access to the Office of the President for consultations on both scientific andadministrative matters.

Organization

The Kavli IPMU has a rather unique organization. While research is conducted in a flatstructure manner with loosely defined grouping, the decision making is done in a top-down
scheme under the Director’s strong leadership. This scheme minimizes the administrative
load for the researchers. It is also intended to maximally extract young researcher’s creative and challenging minds as well as to encourage daily cross-disciplinary interactions.

The Director is obliged to report the appointments of new Principal Investigators and faculty members to the Director of the Todai Institutes for Advanced Study (TODIAS). Also,
to clear the university formality in faculty hiring, the decisions of the Institute have to beendorsed by the Steering Committee of the Kavli IPMU.

Associate Director
Nobuhiko Katayama

The Principal Investigators are world’s leading scientists in their fields. They have a largeautonomy in the research they conduct. They can make proposals to the Director to hire
research staff at the Institute.

Scientific Advisory
Committee

The Scientific Advisory Committee (SAC) gives advice to the Director on hiring scientificstaff and planning scientific strategies. The members are appointed by the Director.

3 . Organization

The Kavli IPMU holds close relations with similar research institutions in the world for encouraging exchanges in research and training of young research staff. We have signed either an agreement or a memorandum of understanding with those institutions.

Foreign institutions/consortia/programs having MOU with the Kavli IPMU
The main laboratory building on the Kashiwa Campus provides a basis for our researchers.
Even most of experimentalists who are involved in Kamioka experiments and astronomical observations spend a good fraction of their time in Kashiwa for analyzing data, sharing seminars and discussing with theorists. The Kamioka Branch is a basis for the Kavli
IPMU staff members who are engaging in the underground experiments conducted at
the Kamioka underground laboratory. The Berkeley Satellite, besides being a place forresearch, serves as a contact place to the US scientific community. We also have a close
collaborative relation with several institutions both in Japan and overseas as well as withother departments within the University of Tokyo.

Function fields and Langlands correspondence
Even though the main goal of arithmetic is to understand number fields, it is observed that function
fields of one variable over finite fields behave quite similarly. Function fields have an advantage that
we can use “geometric methods,” for instance cohomology theories. Not only making us easier to treat
the field, this perspective enables us to “export” ideas of arithmetic to, say, complex geometry. In fact,“geometric Langlands correspondence,” which is a certain correspondence of sheaves on Riemannsurfaces, was formulated under this spirit. It seems geometric Langlands correspondence has somerelation with S-duality, which is a physical theory, but we do not go into further details in this report.

Number theory and Galois
One of the ultimate goals of number theory is to understand the behavior of solutions of algebraic
equations. In Babylonian age, mathematicians already knew formulae to solve certain quadratic equations. Even though this kind of techniques may have been found by practical needs, people were attracted by solving algebraic equations of higher degree in itself. Long after the discovery of solution ofquadratic equations, in 16th century, Italian mathematicians1 found an explicit formula to solve cubic
equation, and immediately after, that for quartic equation. In the course of the finding, they inevitably
needed to deal with square root of negative numbers. This was quite uncomfortable at that time, butlater led to the notion of complex numbers. Without surprise, people stepped forward to quintic equation. However, the structure seemed to be much more complicated than equations that mathematicians
had been treated, and all the attempts ended up in vain.
Breakthrough was achieved by E. Galois, who introduced the notion of “groups” and described the
behavior of algebraic equations in terms of a certain group, now called the Galois group. By analyzing the structure of the group, he succeeded in concluding that solutions for quintic equations cannot
be written in general by means of roots and four basic arithmetic operations.2
Class field theory and Langlands correspondence
Galois groups contain plenty of arithmetic information, and modern arithmetic tries to “understand”
this group. However, how can we say that we understand the group? One of such ways is to describe
it in another way. First achievement in this direction is the celebrated class field theory, developed byHilbert, Takagi, Furtwängler, Artin, Hasse, and others, in early 20th century. They described the abelianized Galois group of a number field K in terms of group of certain functions, called the idèle classgroup, as follows:

Gal(K̅ /K ) ab ≅𝔸K× /K .

However, it is not fully satisfactory since a lot of information is lost by abelianization. It is not straightforward to generalize the class field theory to non-abelian case, but Langlands’ profound insight led
him to propose a fabulous “equivalence” of seemingly unrelated two mathematical objects, now called
the Langlands correspondence. This is a correspondence between representations of Galois group and“automorphic representations,” a representation theoretic generalization of modular forms (i.e., holomorphic functions with certain strong symmetry).
A part of the high non-triviality of the correspondence may be seen from the fact that it is not functorial contrary to most of mathematical theories. Moreover, the resolution of Fermat’s last theorem by A.
Wiles can be seen as an establishment of a very small part of it. This correspondence grew into one of
the Leitmotiv of modern mathematics, not only arithmetic.

Kavli IPMU Annual Report 2013

V. Drinfeld proposed a program to establish the Langlands correspondence for function fields andcarried it out in certain cases. He was awarded Fields medal by this contribution. The method was
expanded by L. Lafforgue who finalized Drinfeld’s program and achieved to establish the correspondence for function fields with full generality. He was awarded Fields medal as well. We can summarize the correspondence in the following picture:ℓ-adicrepresentatiomof Gal (K /̅ K )Research Highlights

Here, K is a “function field” of characteristic 𝑝≠0 (e .g ., 𝔽𝑝((t))), and ℓ is a prime number different
from 𝑝.

𝒑-adic cohomology theory and Langlands correspondence

In the previous paragraph, we took a prime number ℓ which was different from the characteristic of
the function field K . It is known that 𝑝-adic representation of Gal(K̅ /K) is generally quite complicated,
and we are not able to hope for the correspondence. Do we have some other mathematically meaningful object that should replace ℓ-adic representations and describe the 𝑝-adic behavior of K ?

Answering to this question is my main achievement this year (IPMU13-0191 and IPMU13-0192), or
since I have come to Kavli IPMU. Namely, I established a Langlands type correspondence for anothertype of local system called “isocrystal.” The existence of such correspondence was conjectured by P.
Deligne in one of the most influential papers in mathematics (P. Deligne, La Conjecture de Weil II,
Publ. Math. IHES 52, pp.313-428): “Conjecture (1.2.10). — Soient X normal connexe de type fini
sur 𝔽p, et …… (vi) Pour λdivisant p, on espère des petits camarades cristallins .” Isocrystals are,roughly speaking, systems of 𝑝-adic differential equations, and the definition is completely different
from that of ℓ-adic local systems, in other words, ℓ-adic representations of the Galois group. Therefore, it is a big surprise to have such a correspondence.
For a proof, it had been observed by experts that analogous method of Lafforgue in 𝑝-adic cohomology theory might be applicable. However, there had been a lot of obstacles to carry this out, mainlyby the incompleteness of 𝑝-adic cohomology theory. My work was done by constructing a six functor
formalism à la Grothendieck for 𝑝-adic cohomology theory, with which the seeking for “good 𝑝-adic
cohomological framework,” after Monsky and Washnitzer who first defined the 𝑝-adic cohomology

P. Berthelot as a basic tool. Thanks to works of Berthelot, K. Kedlaya, D. Caro and others, six functor formalism had been constructed at least “locally.” My work is, thus, to globalize this construction.
It turned out that this globalization process is quite formal, and the techniques can be used for otherreasonable cohomology theories. Combining with my previous works on the product formula with A.
Marmora, and the theory of weights with Caro, the proof concludes as Drinfeld’s or Lafforgue’s work.

The notion of a manifold is central in both Mathematics and Physics. The first example is the Euclidean space whose geometry was studied since ancient times. It was realized in the 18th and the 19th
century that for many problems in Mathematics and Physics, such as solving a system of algebraic
equations, or various problems in classical mechanics, it is convenient to build new space whosebuilding blocks are Euclidean boxes. Mathematics has always been driven by our sense of beauty. As
mathematicians we have always wanted to work on problems that appeal to us. I think that some of themost interesting problems in Mathematics involve understanding the geometry of some manifold andin some sense all other areas, such as number theory, algebra, or analysis can be viewed as tools to be
used or to be developed for the purposes of geometry.
My main interest is to compute the Gromov-Witten (GW) invariants of a projective manifold X. The
problem can be formulated also via the topological string model in physics. The latter is a specific toymodel that describes the motion of a closed string in X. The GW invariants can be interpreted as theprobability that certain events will occur. Since the trajectory of a string is a surface, mathematicallythe GW invariants can be interpreted as counting surfaces in X satisfying various incidence constraints. Since we can impose many incidence constraints the GW invariants of X are usually infinitely
many and finding a way to describe them is not easy at all.
It was discovered recently by several people that the GW invariants of a manifold X that has semisimple quantum cohomology satisfy the local Eynard-Orantin recursion. In fact, I was also part of this
discovery, which is the content of my paper “The Eynard-Orantin recursion for the total ancestor potential, IPMU12-2014” (accepted in Duke Math. J.). In the beginning of 2013 I managed to make thefirst step in extending the recursion from local to global. As an application, in my paper “Analyticityof the total ancestor potential in singularity theory, arXiv1303.3103” (Adv. in Math. 255 (2014) 217241) I proved a conjecture of Givental about the analyticity of the total ancestor potential as a function
on the deformation parameters. I think that my result can be generalized even further in a sense thatit should be possible to find a global Eynard-Orantin recursion. This is expected to be equivalent tocharacterizing the GW invariants via the representation theory of vertex algebras in the same way as
in my previous work with B. Bakalov “W-constraints for the total ancestor potential for simple singularities, Compositio Math. 149 (2013) 840-888.”
In the 2nd half of 2013 I worked on yet another way to compute GW invariants. Namely, if X has semisimple quantum cohomology, then the invariants can be organized into a generating function, which
is a solution to an integrable hierarchy of evolutionary partial differential equation. This constructionis due Dubrovin and Zhang, modulo certain technical issue, which was resolved by Buryak-ShadrinPosthuma. While Dubrovin and Zhang are using Hamiltonian formalism, I am pursuing a different
direction, which relies on the representation theory of vertex algebras. The goal is to construct Hirota
bilinear equations for the generating function. In collaboration with Y. Shen and H.-H. Tseng I managed to solve this problem when X is a 1-dimensional Fano orbifold: “Gromov-Witten theory of Fanoorbifold curves and ADE-Toda Hierarchies, IPMU14-0013”. I think that our method should work for
all 1-dimensional orbifolds that have semi-simple quantum cohomology. Moreover, this approach will
establish a very interesting connection between the generalized Kac-Moody Lie algebras and orbifold
GW invariants. It is worth noting that for the general case, I discovered a connection to K-theory ofX, which allows me to compute the vertex operators for any manifold X. It turns out that in dimension
more than 1, the vertex operators depend on the values of the Riemann’s zeta function. This explains
to some extent why the approach with Hirota bilinear equations becomes very difficult in dimension
more than 1. At the same time, it looks quite important to continue my work in this direction for targets of dimension more than 1.

Mirror symmetry on primitive forms

Kyoji Saito
We report developments that took place at IPMU in 2013 on LG-LG mirror symmetry using primitive
forms, inspired by physics.
We start with a historical description of primitive forms. One of my main research interests is thestudy of period integrals of differential forms of complex variables, since they often reveal unexpected
deep connections between different areas of mathe- matics. The classical example of a period integral
is the logarithmic integral ∫ d𝑥/𝑥, where the inverse function of its indefinite integral 𝑦 = ∫ 𝑥𝑑𝑥/𝑥 is the
exponential function 𝑥 = 𝑒𝑦, having 2𝜋  –1=∮𝑑𝑥/𝑥 as the fundamental period. Similarly the inverseof the integral ∫𝑑𝑥/ 1–𝑥2 defines the trigonometric function, having 2𝜋 as its fundamental period.
Further examples are the elliptic integrals of the first kind, say ∫𝑑𝑥/ 4𝑥3 –𝑔2 𝑥–𝑔3 or ∫𝑑𝑥/ 𝑥 4 +k1𝑥+k2,
whose inverse functions are doubly periodic elliptic functions (with two basic periods) studied bymany mathematicians including Euler, Abel, Jacobi and Gauss.

Gromov-Witten invariants andrepresentations of infinitedimensional Lie algebras

In a modern understanding, we regard these integrated differential forms as de Rham cohomology
classes of punctured Riemann surfaces of genus 0 or 1, and the period integrals as their evaluations
by homology classes. Then, the Abel-Jacobi theory of period integrals over Riemann surfaces is thehigher- genus generalization of the classical theory, one of the most beautiful achievements of 19th
century mathematics. Furthermore, the cohomological formulation of period integrals on high dimensional varieties, called the (mixed) Hodge theory, is one deep subject in 20th century mathematics.
In spite of those general formulations, I was still attracted by the classical (logarithmic, trigonometric,
and elliptic) integral theories, since they seem to keep structures escaped from the modern formulation. Namely, in those classical theories, the number 𝜇 of linearly independent cycles, on which we integrate periods (i.e., 𝜇=1 for logarithmic and triangular integrals and 𝜇=2 for elliptic integrals) isequal to the number of parameters in the integrals, i.e., two parameters 𝑔2, 𝑔3 or two parameters 𝑘1
and 𝑘2 for the elliptic integrals (they are hidden in logarithmic and trigonometric cases). Then, one
defines the period map by associating to each 𝜇-tuple parameter values 𝜇-tuple period integral values (forinstance, (𝑔2, 𝑔3)↦(𝜔1, 𝜔 2) with 𝜔𝑖 =∮γ𝑖 𝑑𝑥/ 4𝑥3 –𝑔2 𝑥–𝑔3), where γ𝑖  (𝑖=1, …, 𝜇) are linearly independent 1-cycles. The map is not only equi-dimensional by definition, but rather, it is locally homeomorphic. Even if the period map is globally not 1:1 but multi-valued, its inverse map fromthe period domain to the parameter space is a well-defined unique valued map which is invariant
under the monodromy group action. Then, the coordinate components of the inverse map are giv1 𝑔 = Σ (𝑚𝜔 +𝑛𝜔 ) –4, 1 𝑔 = Σ (𝑚𝜔 +𝑛𝜔 ) –6 in the elliptic inteen by Eisenstein series (for instance, 60

gral case).
How could such beautiful phenomena happen? As we discussed already, the number 𝜇 of independent cycles is equal to the number of deformation parameters in the integral. But, let us see a deeper
reason which justifies the name primitive form later: some readers may notice the following puzzle“If there exist 𝜇  linearly independent homology cycles, say γ𝑖 (1≤𝑖≤𝜇), then there also exist 𝜇 linearly independent de Rham cohomology classes. In the above definition of the period map, however, we
integrated only a single differential form, sayζ, but not all 𝜇 classes. Why not integrate all of them?”
The answer is the following: consider 𝜇 classes of differential forms obtained by covariantly differentiating ζ by the 𝜇 parameters, say ∇𝑗ζ(1≤𝑗≤𝜇). It turns out that they form a basis of the de Rham
cohomology group. That is, we obtain all 𝜇 independent period integrals by differentiating thesingle period integral ∮ζ by the parameters, due to a formula 𝜕𝑗∮ζ=∮∇𝑗ζ and non-zero Jacobiandet (𝜕𝑗∮γ𝑖 ζ) 𝜇𝑖𝑗=1 ≠ 0. Let us call this distinguished property of ζ the primitivity.
Kavli IPMU Annual Report 201323

Are the logarithmic, trigonometric, and elliptic integrals the only lucky cases of such primitive integrals? In the early ’70s, guided by such considerations, I researched the literature and found that E.
Picard (1881) and G. Shimura (1964) were studying some particular period integrals having the same
primitivity property as the above. On the other hand, I observed that the theorem of J. Milnor (1970)
says that the number 𝜇 of linearly independent vanishing cycles for an isolated critical point of a holomorphic function is equal to the number of deformation parameters (unfoldings, R. Thom 1975) of thecritical point. It should be the first step toward primitivity. Actually, the logarithmic and trigonometricintegrals correspond to critical points of type A1 and the two elliptic integrals correspond to criticalpoints of type A2 and B2. The Picard and Shimura cases correspond to other critical points.
Thus, it is natural to ask (1) to find a particular de Rham cohomology class ζ satisfying the “primitivity”
on the universal unfolding of any isolated critical point, and (2) to find an intrinsic flat linear coordinate system on the deformation parameter space of the critical point so that the coordinate components of the inverse map of the period map give a new class (which we may call primitive) of automorphic forms. For simple singularities, I found answers shortly later (1979) (1) that the natural weighted
homogeneous volume form (≃Kostant-Kirillov form) satisfies the primitivity, and (2) the flat metric
J on the deformation parameter space (≃𝔥/W), is given by the covariant derivative ∇D I of the Killing
form I with respect to the lowest degree vector field D. Solutions of Levi-Civita connection of the flat
metric J define the flat coordinate system on 𝔥/W (for instance, 𝑔2, 𝑔3 in the elliptic integrals are flat
coordinates). This structure on 𝔥/W is called the flat structure, which is later on axiomatized as a Frobenius manifold structure (Dubrovin 1996).
Guided by this case, I came to the general concept of a primitive form (1980, 1983) enjoying (1) and (2)(actually, (2) is a consequence of (1) by imposing “more conditions” on ζ as follows). Namely, a primitive form is a top degree class in the semi-infinitely filtered relative de Rham cohomology module
on a universal unfolding F of a function having an isolated critical point, and is defined by a systemof higher residue bilinear equations, asking 1. Primitivity: the first order derivatives of ζ by deformation parameters span the first splitting factor of the filtration (by shifting, we obtain a full-splitting of
the filtration), 2. Orthogonality: the splitting factors are orthogonal to each other, 3. Holonomicity:
the second order derivation of ζby the deformation parameters and by the Fourier dual variable of F
remains inside two splitting factors, 4. Homogeneity. The flat structure on the deformation parameter
space is an immediate consequence of these conditions.

According to physics, primitive form theory is mirror dual to the symplectic geometric (A-model)
theories such as Gromov-Witten theory on a compact Kaehler manifold or Fan-Jarvis-Ruan-Witten
theory on a Landau-Ginzburg orbifold (2007, 2013). A mathematically rigorous formulation of the
LG-LG mirror symmetry conjecture claims the coincidence of the total potential function obtained
from a primitive form for F and the generating function of FJRW invariants for the dual function FT.
Precisely, a primitive form induces a flat (Frobenius) structure and its (genus 0) pre-potential on the
deformation parameter space of F. From that data, higher-genus potential is reconstructed on the generic point of the parameter space (Givental, Teleman). There were still difficult problems remaining: 1.
The higher-genus potentials given by Givental needed to be extended to the entire deformation space,
2. We have had neither an explicit formula nor any means to analyze primitive forms except for simple
or simply elliptic singularities (for which cases, see the works FJRW ’07, Krawitz-Shen ’11, MilanovShen ’12). Both problems were solved in the last year at the Kavli IPMU.

T. Milanov (Adv. in Math. 255 (2014)) proved that a semisimple Frobenius structure satisfies a local
Eynard-Orantin (EO) recursion. As an application, he proved the conjecture of Givental on the analytic extendability of the total ancestor potential in whole deformation parameter space. This gives ananswer to the problem 1. In a workshop at IPMU (2012), S. Li presented the idea to approach higher
genus formula by heat kernels. This inspired a collaboration of K. Saito with S. Li and C. Li, where
they developed a new approach to primitive forms that relies on polyvector fields. Furthermore, using
the idea of Barannikov-Kontsevich, they developed the perturbative construction of primitive forms,
in particular, explicit formulae for all weighted homogeneous singularities (arXiv:1311.1659). This
gives an answer to the problem 2. Then, jointly with Y. Shen, an expert in FJRW theory at IPMU, they
confirmed that the LG-LG mirror symmetry holds including negatively weighted deformation parameter (arXiv:1405.4530). It also shows that the 4th derivative of the pre-potential w.r.t. flat coordinates,
corresponding to 4-points correlators in FJRW theory, determines the whole structure. The method isquite general, confirming the LG-LG mirror symmetry; however, the underlying geometric reasonsare still hidden and should be the next target of research.

It turns out that the theory of primitive forms for a function F is relevant in the complex geometric (Bmodel) aspects of N=(2,2) supersymmetric LG (Landau-Ginzburg) theory in physics, having F as its
superpotential (K. Hori). The theory has therefore become a common subject of physicists and mathematicians in Math-String seminar at IPMU. The dualities between different string models in physics
give strong non-perturbative means to calculate the partition functions. For instance, Witten showedthat the Landau-Ginzburg model and the sigma-model on a Calabi-Yau manifold give different phasesof the same physics. The mirror symmetry (worked out by physicists K. Hori, C. Vafa, cf. Kontsevich,
Yau-Zaslov-Strominger) is one of the dualities, which has had a strong impact on mathematics, since
it predicts an unexpected duality between complex geometry and symplectic geometry. We explain
below new developments in this subject, which took place at IPMU in the last year, and confirmed the
LG-LG mirror symmetry using primitive forms.

Flops and S-duality conjecture

Yukinobu Toda
One of my research results in the year 2013 is to prove a flop transformation formula of DonaldsonThomas (DT) invariants counting two dimensional torsion sheaves on Calabi-Yau 3-folds, and give its
application.
In 1998, Thomas introduced the invariants counting stable coherent sheaves on Calabi-Yau 3-folds, asa holomorphic analogue of Casson invariants on real 3-manifolds. It is also a higher dimensional analogue of Donaldson invariants on 4-manifolds, and a mathematical framework of BPS state counting instring theory. If we focus on the DT invariants counting rank one stable sheaves, they count curves on
Calabi-Yau 3folds. In 2004, Maulik-Nekrasov-Okounkov-Pandharipande proposed a conjecture relatingrank one DT invariants and Gromov-Witten invariants. Since then, there have been lots of progress on
the study of rank one DT invariants, especially using wall-crossing formula in the derived categories
of coherent sheaves. For instance, in 2008-2009, I proved (a version of) rationality conjecture of thegenerating series of rank one DT invariants, Pandharipande-Thomas conjecture relating rank one DTinvariants and stable pair invariants, and a flop transformation formula of rank one DT invariants.

In string theory, rank zero DT invariants (i.e., counting
two dimensional torsion sheaves on Calabi-Yau 3-folds)
are also important as they are related to black hole entropy. In 2007, Denef-Moore predicted a formula relatingrank zero DT invariants and Gromov-Witten invariants.
Since these invariants count different kinds of geometricobjects, this is an interesting mathematical prediction.
In order to give a mathematical proof of Denef-Moore’s
conjecture, it is necessary to show that the generating
series of rank zero DT invariants have a modular invariance property, or more precisely, they are (almost) Jacobi
forms. This is interpreted as a 3-dimensional analogue of
Vafa-Witten’s S-duality conjecture in string theory.

In mathematics, there are few works studying rank zero
DT invariants. In my paper ‘Flops and S-duality conjecture, arXiv:1311.7476,’ I proved the flop transformation
formula of the generating series of rank zero DT invarisingular Calabi-Yau 3-fold Z
ants under 3-fold flops. Here a 3-fold flop means that firstcontracting a rational curve C on a Calabi-Yau 3-fold X
to a singular Calabi-Yau 3-fold Z, and then obtaining another Calabi-Yau 3-fold Y by blowing up Z in another way. (See the Figure.) The error term of the flop
formula is described by the Dedekind eta function and the Jacobi theta function, and, in particular, it
is a Jacobi form. This result gives an evidence of a 3-fold version of S-duality conjecture, and an analogue of a blow-up formula for the S-duality conjecture on algebraic surfaces by Yoshioka, Gottscheand Li-Qin.
singular point

Applying the above flop transformation formula, I also proved that the generating series of Euler characteristics of Hilbert schemes of points on surfaces with at worst A type singularities is a modular
form. This result is written in ‘S-duality for surfaces with An type singularities, arXiv:1312.2300.’ So
far many interesting mathematical structures have been found on the Hilbert schemes of points on nonsingular surfaces. However Hilbert schemes of points on singular surfaces have not been expected tohave such structures before the above result. The above result indicates the contrary, and further studyof them are desired.

The Standard Model of particle physics is the most accurate known description of all known matterand its non-gravitational interactions. Even with the enormous experimental data sets generated by theLarge Hadron Collider at CERN, there are essentially no statistically significant deviations observed
from the Standard Model’s predictions. This is particularly striking, given that the LHC is probingenergy scales an order of magnitude or higher than the Standard Model was originally formulated todescribe.
There are nonetheless many peculiar features of the Standard Model that appear arbitrary or contrived. The focus of ‘Beyond Standard Model’ (BSM) model-building is to embed the Standard Model
into a larger theory, applicable at higher energies, that explains these apparently contrived features interms of a more natural structure. The earliest and still important paradigm of BSM model-building
has been the concept of a Grand Unified Theory (GUT).

The nonlinear sigma model: a
new paradigm for physics beyond
the Standard ModelA GUT is a theory in which the forces of the standard model—the U(1) of electromagnetism, theSU(2) of the weak interactions, and the SU(3) of the strong interactions—are all subgroups of a larger
group—in the simplest cases, SU(5) or SO(10). The enlarged gauge groups correspond to an enlarged
set of vector bosons, whose masses define the scale of the GUT, above which the grand unified group
becomes a good approximate symmetry. By “good,” one means that the symmetry is linearly realized,
so that the multiplicities, charges, and interactions of the particles are directly dictated by the representation theory of the GUT group.
By “linearly realized,” we mean that the group transformations act as rotations, rather than shifts, on
the internal spin-like degrees of freedom. Another way of expressing the condition of linear realization is that the symmetry does not change the vacuum, but only permutes the quantum state of particles or ripples on quantum fields in the vacuum.
GUT models have a lot of beauty, elegance, and simplicity, as well as extending the ideas of electroweak unification to solve a new set of problems. However GUTs also have problems that bring theminto conflict with observation. For instance, GUTs typically have violations of conservation laws thatare larger than observations permit. These are associated with the problems of doublet-triplet splitting
and proton decay, for example.
These problems are directly associated with the virtual effects of the massive vector bosons corresponding to the additional generators of the GUT group. Of course, these effects are tiny when the massive
vector bosons are very massive, in accordance with the principle that massive states decouple from lowenergy processes. However, low energy experiments are sufficiently precise and constraining as to ruleout the simplest GUTs, even when the GUT scale is as high as it can reasonably be made, some 1016 GeV,
just an order of magnitude below the scale where quantum gravity becomes important.
Therefore it is advantageous to search for a theory that does away with the unwanted effects of the massive vector bosons of GUTs, while retaining the attractive features of GUTs, such as charge quantization.
In a paper by T. Yanagida, J. Kehayias and myself, we demonstrated the viability of a radical yet
simple alternative to grand unification. Our BSM model is based on the idea of the Nonlinear SigmaModel (NLSM). The NLSM is an old concept in theoretical particle physics, based on the idea of thenonlinear realization of symmetry groups. That is, some symmetries of the system may be realized as(internal) shifts rather than as (internal) rotations. Equivalently, some of the symmetries may change
not only the particles propagating through empty space, but empty space itself. This is the mechanism

The NLSM scneario has the potential to solve many phenomenological problems that are difficult toresolve in the GUT framework. Most immediately, the small violations of conservation laws due to effects of virtual massive vector bosons are absent in the NLSM framework because... there are no massive vector bosons to generate those effects!

Recently the Planck satellite has provided the map of cosmic microwave background (CMB) anisotropy with unprecedented accuracy. The measurements of CMB anisotropy by the Planck satellite andthe WMAP satellite clearly confirmed the idea of inflation in the early universe; inflation generally
predicts nearly scale-invariant power spectrum of the curvature perturbation, which nicely agrees withobservations. The next issue is to pin down the inflation model, or to identify the inflaton, the scalar
field which drives the inflationary expansion.

The enterprise of BSM model-building can benefit from the promising features of the NLSM only
if the NLSM preserves the important phenomenological successes of GUTs. One key success of the
GUT framework is the quantization of “weak hypercharge”—the U(1) factor of the SM gauge groupthat determines the electric charges of elementary particles after electroweak symmetry breaking.

One of the simplest inflation models is the so-called chaotic inflation (A. Linde, 1983). In the chaotic
inflation model, the inflaton has just a power-law potential. Inflation occurs while the inflaton fieldrolls down the potential at the over Planckian field value. Interestingly, it predicts a large tensor perturbation power spectrum, or large tensor-to-scalar ratio, which can be seen as the B-mode polarization in the CMB anisotropy. Some CMB experiments dedicated for the B-mode polarization are ongoing and are expected to discover the B-mode signal if the chaotic inflation model is true.

The massive vector bosons, X, of the GUT group, typically mediate
processes that turn quarks into leptons, leading to proton decay.

Remarkably, it appears that the hypercharge assignments of the particles of the Standard Model all
satisfy these baroque constraints. In fact, there is more than one way to satisfy them. There is a discrete choice of ways to assign hypercharge to the Standard Model particles in the NLSM embedding,with each embedding corresponding to a distinct and potentially phenomenologically viable model.
My co-authors and I are still exploring the many possibilities. However one bears special mention,and has resulted in a second paper by us. We have shown that when the electroweak SU(2) × U(1) isembedded in a nonlinearly realized SU(3) of the ℂℙ2 model, one possible choice of hypercharge assignments—the minimal one—results in the identification of the Nambu-Goldstone bosons of the
NLSM being identified with the Higgs boson. Prior to coupling the NLSM to gauge fields, the mass ofthe Higgs in this model is exactly zero, in accordance with Goldstone’s theorem. In other words, theHiggs boson is light not because of fine-tuning of its mass, but because of a symmetry principle that
holds in a certain limit. Completely unexpectedly, we find that the NLSM provides a natural mechanism for solving the electroweak hierarchy problem!
To conclude, we find that the NLSM idea provides a framework for BSM model-building that runs on
a track parallel to the GUT paradigm, but solves many of its intractable problems while preserving its
successes. This idea, a home-grown product of the Kavli IPMU research environment, will hopefully
be a fertile ground for interesting ideas in the future.

Remarkably, we have found that the U(1) hypercharge assignments in the NLSM are indeed quantizedby virtue of the embedding of hypercharge into a nonabelian simple group—despite that fact that thehidden symmetries of the group are never restored at any energy scale, and do not act on elementary
particles at all!
Furthermore, the possible values of the weak
hypercharge for a given elementary particle
are correlated with its representation under theother unbroken parts of the symmetry group.
For instance, in the case of the ℂℙ2 NLSM,
where U(1) and SU(2) are embedded in a nonlinearly realized electroweak SU(3), the weak
hypercharge of an SU(2) doublet must be nonzero and equal to an odd number of a certain
minimum unit. When the full SM gauge groupis embedded into a larger nonabelian groupsuch as SU(5), the quantization rules for weak
hypercharge are even more tightly specified,being dictated by a particle’s SU(2) and SU(3)representations.

Our model is similar to a GUT in that the Standard Model gauge group SU(3) × SU(2) × U(1) may beembedded in a larger simple group G. The difference is that the additional symmetries of G beyond
those of the standard model are completely nonlinearly realized at all energy scales. This is in contrast
to the situation in a GUT, where the hidden symmetries are linearly realized at some higher scale but
spontaneously broken at low energies.

While the chaotic inflation is a simple and interesting idea,
there seem to have been some prejudice on the chaotic inflation that its prediction is so robust that non detection of Bmode would exclude the idea of chaotic inflation. Nakayama,
Takahashi and Yanagida (2013) proposed the so-called polynomial chaotic inflation model, in which it was shown that
adding extra power-law potential significantly modifies theoriginal prediction of chaotic inflation with a single powerlaw potential. It opens up a new possibility that relatively
small, but observable tensor-to-scalar ratio can easily be generated. The authors also successfully put the model into theframework of supergravity, based on the early idea of Kawasaki, Yamaguchi and Yanagida (2000). The authors also
proposed that the polynomial chaotic inflation can be causedby the right-handed sneutrino (the superpartner of the righthanded neutrino), extending the idea of Murayama, Suzuki,
Yanagida, Yokoyama (1994). This is an interesting scenario,
because the baryon asymmetry of the universe is automatically created by the decay of right-handed sneutrino.
Note: Very recently (Mar. 2014), the BICEP2 experiment reported thedetection of the primordial B-mode with 7 sigma level (arXiv:1403.3985). It
may indicate the chaotic inflation model with quadratic potential. Althoughmore observations and analyses will be needed to accurately determine thetensor-to-scalar ratio, if any deviation from the quadratic potential prediction
is found, the idea of polynomial chaotic inflation will be important.

Higgs doublet β as a function of the fine-tuned light Higgs
boson mass. Here, we assume that the supersymmetry
breaking is at the Planck scale. In the figure we allow thesoft masses of the two Higgs doublets to vary by 10% (blueband) and by 20 % (light blue band).

Motivated by this observation, we proposed a new possibility
to explain the shallowness of the Higgs potential. In our scenario, the vanishingly small quartic coupling at the Planckscale is realized as an outcome of the electroweak fine-tuning
in a class of models with Planck scale supersymmetry breaking [1]. When the supersymmetry breaking masses of the Higgs doublets are at the Planck scale, afine-tuning condition that we are left with one light Higgs doublet leads to an almost 45 degree mixing
between the two Higgs doublets when the two Higgs doublets have similar supersymmetry breaking
masses (see Fig 1). Since the direction of the 45 degree mixing of the Higgs doublets corresponds tothe so-called D-flat direction of the Higgs potential, the resultant Higgs pontential is almost vanishing(see Fig 2). In this way, we can explain the shallowness of the Higgs potential in a model with Planckscale supersymmetry breaking. It is an intriguing feature of this mechanism that the shallowness ofthe Higgs potential is caused by the electroweak fine-tuning in the Higgs mass parameters. Future
precise determinations of the Standard Model parameters at the ILC experiment will make it possible
to test this scenario.

To understand the origin of the weak boson mass scale is a remaining puzzle of the Standard model.
The weak boson masses originate from the vacuum expectation value of the Higgs field once theelectroweak symmetry is spontaneously broken. It is known that the observed weak boson masses are
explained with the Higgs vacuum expectation value of 174 GeV. However, the Standard model does
not tell us that why the electroweak symmetry is spontaneously broken and why the vacuum expectation value is not the Planck scale but as small as 174 GeV; the Higgs potential has a negative quadraticterm of the order of (100 GeV) 2, although the radiative corrections generate a mass squared of theorder of (1018 GeV)2. The correct Higgs potential is obtained only with a huge fine-tuning; a bare parameter of the Higgs potential should be chosen very accurately such that (1018 GeV)2 is subtracted toleave (100 GeV)2.
In order to understand the origin of the weak boson mass scale, we proposed the “Focus Point Gaugino Mediation Model,” based on the supersymmetric Standard model. In this model, only gaugino
masses arise at the beginning, i.e., at the high-energy scale (the grand unified theory scale). The quadratic term of the Higgs potential as well as the other super-partner masses are generated from thegaugino loops at the low-energy. The radiatively generated quadratic term of the Higgs potential turns
out to be negative, and hence, the spontaneous breakdown of the electroweak symmetry breaking isnaturally explained. The scalar particles, which are the superpartners of the Standard Model fermions,have flavor universal masses. This feature is attractive since there is no flavor changing neutral current
problem, which is a crucial obstacle for the low-scale supersymmetric models.
In the Focus Point Gaugino Mediation, the ratio of the Wino mass (M2) to gluino mass (M3) is fixed
to the integer ratio 8/3 at the grand unified theory scale. As a result, the quadratic term of the Higgs
potential becomes naturally of the order of (100 GeV)2 (right panel of the figure); the Higgs vacuum
expectation of 174 GeV is obtained without a large fine-tuning. Remarkably, the size of the quadraticterm in the Higgs potential is insensitive to a superpartner mass. This behavior is rather nontrivial,
and is in contrast to other supersymmetric models with a universal gaugino mass. In these models, thequadratic terms of the Higgs potential at the low energy are as large as a mass squared of a superpartner (2000–3000 GeV)2 (left panel of the figure). Consequently, the vacuum expectation value of 174
GeV is obtained only with a large fine-tuning that a supersymmetric mass term is added to reproduce
the (100 GeV)2 quadratic term. In the Focus Point Gaugino Mediation model, thanks to the integer ratio of M2 /M3 = 8/3, the origin of the weak boson mass scale is naturally understood. The superpartnerof the Higgs boson, Higgsino, is predicted to be light, and is a candidate for a dark matter. This is aconsequence of the small fine-tuning of the Higgs potential.

After the discovery of the Higgs boson at the LHC experiments, there is ongoing discussion as to what we can learn
from the observed Higgs mass. In particular, we keep contemplating the origin of the electroweak scale. In addition tothis longstanding problem in the Standard Model, however,
the measured Higgs boson mass at around 126 GeV seems topose a new puzzle; why the Higgs potential is so shallow. As
is well known, the Higgs boson mass is related to the quartic
coupling of the Higgs potential which determines the behavior of the Higgs potential at the large field value. From themeasured Higgs boson mass, the quartic coupling is found to
be around 0.1, and hence, the Higgs potential is found to bequite shallow. Furthermore, the extrapolated Higgs quartic
coupling towards the higher energy scale seems to vanish ataround the Planck scale within the uncertainties of the Standard Model parameters.

may have masses between 10 -6 and 10 -3 eV and hardly be detected, and therefore they are called invisible axions. But axion-like particles, for example, may be produced in the sun and can be detected by
XMASS through the axio-electric effect. The production rate, the energy spectrum, and the detection
mechanism are known and calculated very well. We looked for such solar axions, but no evidence wasseen, and the most stringent result on the axion-electron coupling, λ aee, was obtained [3].

Latest results and statusof the XMASS experiment
Yoichiro Suzuki
The aim of XMASS [1] is to detect dark matter directly in the largest liquid Xenon detector in theworld placed underground in the Kamioka Observatory, in Japan.
There are many indications that dark matter exists through the observations of the gravitational effects
in the Universe such as the measurement of the rotation velocity of galaxies and so on. Dark matter
consists of about 27% of the energy and matter of the Universe, but its nature is not yet determined.
Dark matter is thought to be a new kind of particles that can therefore be detected in terrestrial detectors though particle interaction. Once we detect dark matter, it may reveal the nature of dark mater
particles.

WIMPs have masses of weak scale andan annihilation rate of order weak interactions to ordinary matter. We here
looked for keV region dark matter with
the interaction cross-section of superweak, a few orders weaker than theusual weak interactions. One motivation
was that the small crumps seen in galactic scale in a calculation to simulate
development of the large-scale structure
by a standard cold dark matter scenario
would be avoided. The similar data set
and methods of the inelastic scattering
analysis mentioned above were used tolook for the keV Bosonic super-WIMPs.
We specifically look for vector andpseudo-scalar particles. No candidate
excess was found and the limit we set
was the best results [5] for this kind of
searches as shown in Fig. 2.

XMASS detects dark matter by observing the energy deposited in the target material by the recoil
nucleus that a dark matter particle kicked off. XMASS is a single-phase low temperature liquid xenon
detector with a total target mass of about 850 kg and a fiducial mass of 150 kg. Interactions of dark
matter in the target mass are very rare, and it is therefore necessary to make the background level ofthe detector very low. Our original aim was to reach the background level of about a few events per
day in the fiducial mass. It is an extreme challenge to achieve this level.
Unfortunately, we have found unexpected backgrounds in theinitial commissioning phase, that stemmed from the radioactive
contaminants of aluminum used as a seal between the quartzwindows and metal-bodies of the low background light sensors.
In order to reduce the effect from this obstacle, we have decided
to cover those parts with an OFC ring since we were not able toremove the aluminum completely unless we replace all the lightsensors to new ones. This refurbishment work was completed in
November 2013 and we have started taking data again.

Fig. 1. Situation‌of low mass dark matter. Regions show positive
claim and lines are upper limits.

Although we could not remove the dirty aluminum but rather
just put covers on, we have achieved about one order of magnitude of reduction of the background above 5 keV from thealuminum origin, and obtained more than two orders of magnitude reduction in the fiducial masses. We are now taking data
stably and continuously.
In FY 2013, we have analyzed the data taken in the commissioning phase before the refurbishment.

Events in the entire mass of 850 kg inside of the photo sensor surface were used. For this whole volume analysis the energy threshold of 0.3 keV was achieved due to the high light yield of 14 photoelectrons per keV, which was the lowest among other dark matter experiments. Unfortunately the event
vertex reconstruction does not work in such a low energy region. We therefore have to use the entire
volume for the physics analysis. With only 6.8 days of data [2] and applying a simple cut that removes
only characteristic Cherenkov events happening in the PMT quartz windows, our results have stepped
into the interesting parameter region, as shown in Fig. 1, where the DAMA/LIBRA group claimed
that they saw an annual time variation in their accumulated data for the last 13 years. This demonstrated the advantage of the large target mass and lower energy threshold of XMASS.
Another advantage of XMASS is the ability to detect e/γ events as well as nuclear recoils. Axionlike particles can be observed by looking for e/γ events in the detector. Possible dark matter axions

We have demonstrated the advantage of the large target mass and very low energy threshold of
XMASS by the physics results from the a in the commissioning phase. After the refurbishment workthat ended in November 2013, we have been taking data continuously, and we will therefore accumulate stable data more than one year by the end of this year. Even with the same background level as in
the commissioning phase, we are able to make an annual modulation measurement with higher sensitivity than the DAMA/LIBRA group. But for a higher WIMPs
mass region, although the background was reduced by morethan two orders of magnitude, our sensitivity was still limitedby the same background source since the dirty aluminum was
not removed, but rather just covered by the metal rings. Therefore a competitive sensitivity in the high mass region will be
aimed in our next phase detector, XMASS1.5, where we will
have a 1 ton fiducial mass, and we will exploit new ideas to reduce the surface backgrounds. We have already demonstrated
that we are able to get into the region below σSI < 10 -46 cm2, asshown in Fig. 3.

WIMP-nucleon Cross Section［cm2］10-39

Research Highlights

The γ-rays from de-excitation of the excited state of 129Xe are signatures of the inelastic scattering of
dark matter. For this case, 39.58 keV γ-rays or internal conversion electrons plus characteristic X-rays
are observed, in addition to the small energy deposition from recoil nucleus. Since the energy of thesignature is high enough for the vertex reconstruction to work very effectively in this energy region,
we have used 41 kg of the inner most volume of the detector as a fiducial volume. The background level of 3×10 -4 ev/keV/kg/day was obtained. With such a low background level, we could perform very
sensitive measurement without subtracting backgrounds. The obtained upper limit for the inelastic
cross section [4] was 3.2 pb for the 50 GeV WIMPs that is the best limit obtained so far through thiskind of method.

Status of the T2K experimentMark Hartz

The ND280 detector is used to measure the neutrino interaction rates close to their production point,where oscillation effects are negligible. These measurements are used to study the composition of theneutrino beam and the details of neutrino interactions in the detector. The ND280 measurements thenprovide a precise prediction of the neutrino interaction rates at SK for each neutrino oscillation hypothesis that is tested against the SK neutrino interaction data.

Research Highlights

The T2K experiment generates of a beam of muon neutrinos (ν𝜇) at the J-PARC accelerator in Tokaimura by colliding high energy protons with a graphite target. A very small fraction of the neutrinos
interact either at a detector located 280 m from the production point, called ND280, or at the SuperKamiokande (SK) detector, located 295 km away. The interactions of ν𝜇 and electron neutrinos (νe ) produce muons and electrons respectively, which are detected by the Cherenkov light they produce in the
SK detector. Since the SK detector can differentiate between muons and electrons, the νe interactions
can be identified. T2K looks for the appearance of νe at SK from ν𝜇→νe oscillations. The rate at which
this transition happens depends primarily on two mixing angles, θ 13 and θ 23. The rate also depends on
the phase δ CP that allows for CP violation.

δcp

Neutrino oscillations, are a phenomenon where one type or “flavor” of neutrino oscillates to anotheras the neutrino travels through matter or vacuum. The discovery of neutrino oscillations confirmed theexistence of small but non-zero neutrino masses, evidence of physics beyond the Standard Model ofparticle physics. Now the Tokai-to-Kamioka (T2K) experiment has begun the search for Charge-Parity(CP) violation in the oscillations of neutrinos. In a CP violating process, the laws governing matter andantimatter are different. If CP violation by neutrinos is found, it may explain why the universe is madeof matter only, and not equal parts of matter and antimatter, through the process of leptogenesis.

T2K detected the first indication of ν𝜇→νe oscillations in 2011 with the observation of 6 νe candidate
events at the SK detector (Phys. Rev. Lett. 107 (2011) 041801). In July of 2013, T2K reported the observation of 28 νe candidate events with a data set 4 times larger than the 2011 results (Phys. Rev. Lett. 112(2014) 061802). These events, shown in Fig. 1, have a statistical significance of 7.3σ , constituting a discovery of the ν𝜇→νe oscillation phenomenon.

The ν𝜇→νe oscillation channel is the first observed mode of oscillations that can be used to probe thepresence of CP violation in neutrino oscillations. If CP violation is present, the rate of ν𝜇→νe oscillations will be different for neutrinos and antineutrinos. By combining T2K measurements of ν𝜇→νe oscillations with reactor measurements of anti-νe →anti-νe oscillations and the T2K measurement of ν𝜇→ν𝜇survival, the first constraints on δ CP have been made, as shown in Fig. 2. While the constraint is still
weak, an indication of CP violation in the mixing of neutrinos has been observed.
The ultimate test of CP violation will come from the measurement of ν𝜇→νe oscillations for both neutrinos and antineutrinos. Now that T2K has discovered this transition for neutrinos, T2K has started operating with an antineutrino configuration for the beam. Since neutrinos and antineutrinos are produced
and interact at different rates, a significant challenge for T2K will be the combined analysis of neutrino
and antineutrino data with the proper accounting of all systematic effects.

with ever improving precision over the coming years. The measurements of δ CP and the other parameter
governing the oscillations of neutrinos promise to shed light on our fundamental understanding of theStandard Model and the processes in the early university that gave rise to the imbalance of matter andantimatter.

Current status of EGADS

Research Highlights

Mark Vagins

Following 18 months of construction, EGADS first became operational in 2011, initially running withpure water. Various adjustments and tuning of the equipment followed, and by 2013, once it had been
demonstrated that the filtered pure water in EGADS was equal in quality to that in Super-K, 400 kilograms of gadolinium sulfate—a world’s record—was dissolved in the 200 ton main tank, allowing
large-scale studies of gadolinium filtration and transparency to begin. The EGADS selective filtration
system has achieved a gadolinium retention rate of 99.97% per pass, while simultaneously cleaning
unwanted impurities from the water: unprecedented, and a major technical achievement.

Several years ago, Kavli IPMU Professor Mark Vagins and theorist John Beacom suggested adding
100 tons of gadolinium sulfate to Super-Kamiokande as a way—among other benefts—to detect the
diffuse fux of supernova neutrinos produced by all the core collapse explosions since the onset of starformation. These ancient supernova neutrinos could provide a steady stream of information about not
only stellar collapse and nucleosynthesis but also on the evolving size, speed, and nature of the cosmos itself. This ambitious plan is called GADZOOKS!, for Gadolinium Antineutrino Detector Zealously Outperforming Old Kamiokande, Super!
In order to demonstrate the safety and effectiveness of this approach, a dedicated gadolinium test
facility has been constructed underground in the Kamioka mine near Super-K. Led by Vagins andKavli IPMU PI Masayuki Nakahata, this large-scale R&D project is called EGADS: Evaluating
Gadolinium’s Action on Detector Systems. It includes a 200 ton scale model of Super-K completewith 240 photomultiplier tubes (227 50-cm Super-K style tubes plus an additional 13 prototype tubes
being evaluated for use in the proposed Hyper-Kamiokande project), and a novel selective water filtration system. The picture above shows the view inside the experimental hall, while the one to the rightshows a view inside the EGADS tank itself during construction. An event display of a downwardgoing cosmic ray muon is also shown.

Kavli IPMU Annual Report 2013

Now, with full gadolinium loading we are within 15% of the transparency of ultrapure water. This isprobably already sufficient, but work continues to improve upon this result. Further comparative studies both with and without dissolved gadolinium in the 200 ton tank will take place during 2014. If allcontinues to go well, we expect be ready to introduce gadolinium into Super-Kamiokande sometime
within the next few years.
And what will happen to the extensive EGADS facility after that? As part of a 2012-2017 MEXT Research in Priority Areas grant for multimessenger astronomy received by Vagins, as soon as the R&D
phase of the project is completed in 2014 EGADS will be converted into the world’s most advanced
supernova neutrino detector. While still called EGADS, the acronym’s meaning will change to: Employing Gadolinium to Autonomously Detect Supernovas. During this new phase of its existence
EGADS will utilize the unique properties of gadolinium to instantly identify supernova explosions in
the Milky Way galaxy. Hooked into a Japanese network of optical, X-ray, gamma-ray, infrared, andgravitational wave observatories, EGADS will be able to alert the other members that a supernova isoccurring while the neutrinos from the blast are still passing through the Earth. Such an alert can beissued hours before the arrival of the various electromagnetic signals, as they are generated considerably later in the explosive event than are the neutrinos. Therefore, following its role as a pioneering
R&D laboratory, EGADS is now poised to become the first facility in the world to detect—and announce—the next supernova explosion in our galaxy.

Measurement of the dark matter
distribution in fifty galaxy clusters
Masahiro Takada

Few scientists seriously doubt the existence of dark matter, which researchers discovered almost
eighty years ago. Nevertheless, astronomers cannot directly see dark matter in the night sky, andparticle physicists have not yet identified a dark matter particle in their experiments. “What is dark
matter?” is a big unanswered question facing astronomers and particle physicists, especially because
invisible dark matter probably makes up 85% of the mass of the Universe.
We used the Subaru Prime Focus Camera (Suprime-Cam) to investigate the nature of dark matter bymeasuring its density in fifty galaxy clusters, the most massive objects in the Universe. We wanted touse a large sample of galaxy clusters to find out how the density of dark matter changes from the center of a typical galaxy cluster to its outskirts.
The density of dark matter depends on the properties of the individual dark matter particles, just likethe density of everyday materials depends on their components. CDM, the leading theory about dark
matter to date, describes that dark matter particles only interact with each other and with other mattervia the force of gravity; they do not emit or absorb electromagnetic radiation and are difficult if not
impossible to see. Therefore, we chose to observe dark matter by using gravitational lensing, which
detects its presence through its gravitational interactions with ordinary matter and radiation. According to Einstein’s theory of relativity, light from a very distant bright source bends around a massive
object, e.g. , a cluster of galaxies, between the source object and the observer. It follows from this principle that the dark matter in cosmic giants like galaxy clusters alters the apparent shape and positionof distant galaxies. The Subaru Telescope allows us to measure very precisely how the dark matter ingalaxy clusters distorts light from distant galaxies and gauge tiny changes in the appearance of a huge
number of faint galaxies (Figure 1).

We combined measurements from observations of fifty of the most massive known galaxy clusters to
calculate their concentration parameter. The average mass map (Figure 2) is remarkably symmetricalwith a pronounced mass peak. The mass density distribution for individual clusters shows a wide range
of densities. We found that the density of dark matter increases from the edges to the center of the cluster, and that the concentration parameter of galaxy clusters in the near Universe aligns with CDM theory. Past research based on a small number of clusters found that they had large concentration parametersand did not conform to CDM theory. In Contrast, measurement of the average concentration parameterfrom a large number of clusters yielded a different result, which supports CDM theory.

Outline of Gravitational Lensing Analysis
Step 1

CDM theory describes how dark matter in galaxy clusters changes from its dense center to its lower
density edges in two ways. One is a simple measure of the galaxy cluster’s mass, the amount of matterthat it contains. The other is a concentration parameter, which is a single measurement of the cluster’s
average density, how compact it is. CDM theory predicts that central regions of galaxy clusters have a
low concentration parameter while individual galaxies have a high concentration parameter.
Research Highlights

We, an international team of astronomers*1 from Taiwan, England, and Japan, have used the Subaru
Telescope to measure the distribution of dark matter in fifty galaxy clusters and found that its density
gradually decreases from the center of these cosmic giants to their diffuse outskirts. This new evidence about the mysterious dark matter that pervades our Universe conforms to the predictions of cold
dark matter theory, known as “CDM.”*1 The members of this research team are also team members of the “Local Cluster Substructure Survey (LoCuSS),” aninternational consortium of astronomers studying galaxy clusters, as part of the global research effort to answer big, open
questions about the cosmos, including the nature of dark matter. More information about the LoCuSS consortium is available

The Subaru FMOS-COSMOS surveyof star-forming galaxies at high redshift
John Silverman

The COSMOS survey is designed to examine the role of the environment on the formation and evolution of galaxies with cosmic time. Determining whether the individual properties of galaxies, such as
their rate of growth, are connected to the larger-scale environment catapults us into discovering what
factors in the early Universe have shaped the current form of local galaxies. One part of that investigation is carrying out an intensive program of research using FMOS on the Subaru Telescope to acquirenear-infrared spectra of over 1000 galaxies when the Universe was at the young age of 4 billion years
old. This survey is ushering in the era of large spectroscopic efforts with the Subaru Telescope thatwill fully blossom with Prime-Focus-Spectrograph in the coming years.
One key to generating fruitful results is an international collaboration between COSMOS researchers
to maximize optimal use of FMOS. In this project, researchers from Kavli IPMU and the Institute for
Astronomy at the University of Hawaii formed an effective collaboration to implement our goal. The
observations spanned 20 nights of observations starting in March 2012.

Using the Fiber-Multi-Object Spectrograph (FMOS) mounted on the Subaru Telescope, a team ofastronomers, led by John Silverman, is mapping the large-scale distribution of galaxies in the Cosmological Evolution Survey (COSMOS) at z ∼ 1.6. First results demonstrate that galaxies, over nine billion years ago, provided a nurturing environment for the birth of new stars at remarkable rates whileat the same time in an orderly manner. Even at these early times, there are signs of maturation, since
the surroundings of massive galaxies were relatively dusty and enriched by heavier elements.

Another important key to making our ambitious goal a reality is the advanced technology that FMOS
offers to researchers. FMOS is a fiber-fed, near-infrared spectrograph that can acquire spectra from
400 galaxies simultaneously with a wide field of coverage of 30 arc minutes at prime-focus. Being
able to capture so many objects in such a wide field of view is useful for a range of purposes: fromstudying galaxy evolution and variation with the galaxy environment to investigating star-forming regions, cluster formation, and cosmology. FMOS provides unprecedented views of the distant Universeby using fiber optic cables to collect the light of multiple objects over an area of the sky equal to thatspanned by our Moon and also by using a built-in filter to remove unwanted bright emissions from thewarm night sky.

FMOS has now been operating in a high-spectral resolution mode, and its highly successful rate ofdetection is testimony to the realization of the instrument’s full potential. Figure 1 displays the emission lines from a single FMOS pointing, which detected the following chemical species from the interstellar medium of high-redshift galaxies: hydrogen: Hα and Hβ , nitrogen: [NII], and oxygen: [OIII].
These so called “spectral signatures” provide a measure of the distance to the galaxy (i.e., its redshift).
The ratio of the intensity of Hβ relative to Hα provides a measure of obscuring dust. The strengthof the emission lines indicates the rate at which stars are forming while the ratio of [NII] relative to
Hα is indicative of the level of chemical enrichment of the interstellar medium (i.e., metallicity). The
FMOS-COSMOS survey is the largest near-infrared spectroscopic survey of galaxies at high spectral
resolution and high redshift yet to be undertaken. Scientific results include the following:1) Galaxy growth and a star-forming ‘main sequence.’ There is a highly ordered, general decline in
the rate at which galaxies form stars over cosmic time. The FMOS observations shown in Figure 2
confirm that the rate of star formation varies with the total mass in stars. Although this relationshipwas first seen locally, this research shows that star formation not only persisted in early epochs but
also that its rates of star formation were 20 times higher then! The star formation rate increases witha look-back time out to a corresponding redshift of z ∼ 1.6. While this has been observed using otherindicators (ultraviolet or infrared) at high redshift, FMOS’s detection of the Hα emission line in thenear infrared provides a consistent way to measure star formation in the early Universe and compare itwith that of local galaxies.
2) Early dust formation and chemical enrichment. The galaxies observed with FMOS have significantly lower levels of chemical enrichment of gas (based on the ratio of nitrogen to hydrogen) in theirinterstellar medium than galaxies of the same mass in the local Universe near us (Figure 3). This finding agrees with a portrait of galaxies that have room to grow and are accreting pristine gas that fuels
their intense star formation. Larger amounts of dust and metal content indicate that the more massive
galaxies at z ∼ 1.6 have evolved more fully and are similar to mature local galaxies that have stopped
star formation.

Evolution of the stellar-to-dark matter
relation: separating star-forming
and passive galaxies from z = 1 to 0
Alexie Leauthaud
In our current understanding of galaxy formation, galaxies are thought to reside in large over-densities
of dark matter, named “dark matter halos.” The total mass and structure of dark matter halos arethought to play an important role in determining the fate of galaxies within. Exactly what role thedark matter environment plays though in determining galaxy formation, is not well known and is anactive field of research. Previous research has shown that the dark matter mass of dark matter halos
correlates strongly with galaxy mass, suggesting a tight connection between galaxy growth and halo
growth. Galaxies however, are known to come in several varieties. For example, galaxies are often
classified as being either “blue” or “red” based on the strength of their star formation. Galaxies alsopresent various morphological classes, the two most common classes of which are galaxies with spiralarms, and those that are elliptical in shape with no presence of spiral arms. Does the dark matter also
play a role in determining galaxy types? This is the question that we sought out to investigate.

The FMOS-COSMOS survey has completed its goal of having over 1000 galaxies with redshifts tomap large-scale structure. While the current survey spans a sky area of one square degree in high-resolution mode, future efforts with FMOS may expand the areal coverage and complement instruments
at other telescopes, which have wider spectral coverage or deeper penetrating power but are limited
by a small area of coverage. Such complementarity may allow FMOS to detect the first structures (i.e.,sites of higher than average density of galaxies) that likely evolved into the massive clusters that we
see today.

3) Supermassive black hole growth. FMOS has enabled us to measure the masses of supermassive
black holes by the detection of highly velocity-broadened emission lines, namely Hα and Hβ , thatreach up to ∼10,000 km s-1. We have confirmed that such determinations of mass are reliable by comparing to other indicators (MgII). With close to 100 actively accreting supermassive black holes identified by their X-ray emission, we have shown that the rate of accretion onto massive black holes has
an impact on the distribution of electron energies in the overlaying corona as seen in a hardening of
the X-ray spectrum. This result solidifies previous studies that were based on heterogeneous samples
and sheds light on the physics of accretion disks. Further investigations are underway to understandthe motions of gas in the vicinity of a massive black hole and whether any additional kinematic signatures may indicate how black holes are fed (inflow) or shut off possibly due to an outflowing wind orradiation pressure.

One of the main difficulties in this type of investigation, isdetermining how to measure the properties of the dark matter halos that surround galaxies. How can we measure theproperties of dark matter when dark matter is invisible? One
way in which we can probe dark matter is to use a techniquecalled gravitational lensing. Gravitational lensing is the bending of light caused by massive objects in the universe andleads to small distortions in the shapes of background galaxies. Measurements of the very small, percent level changes inthe shapes of background galaxies are known as “weak lensing.” In order to carry out this investigation, we performed
weak lensing measurements around sets of galaxies takenfrom a large Hubble Space Telescope Survey (known as the
COSMOS field) and studied their dark matter properties as afunction of galaxy mass and galaxy color. The high quality
imaging from the Hubble Space Telescope enabled us to perform these measurements as various epochs in the universe,
the first time that this has been possible.

The results of this study conclusively showed the unexpected result that not only the dark matter environment of galaxies is strongly correlated with galaxy color, but that the form of this trend inverts
over the history of the universe. The figure highlights this effect that was published in Tinker et al.
2013. This Figure shows that for small galaxies, red and blue galaxies live in similar dark matter environments. For massive galaxies however, when the Universe was young, blue galaxies lived in more
massive halos. In the universe that we live in today however, red galaxies live in more massive halos.
Why and how this surprising trend arises is yet unexplained. Work in actively underway to try and understand how this link between galaxy color and halo mass might be established.
This type of investigation will be measured with much larger signal-to-noise by the Hyper SuprimeCam (HSC) survey that has just started on the Subaru Telescope. The HSC survey will image 1400
square degrees of the sky over the course of 5 years with the primary goal of performing weak lensing
measurements. In the very close future, we will be able to investigate these trends using HSC with exquisite precision, yielding strong insights into the connection between dark matter and galaxy formation.

The spectroscopic observations of PS1-10afx revealed the characteristic signature of a Type Ia supernova. Hydrogen, the most common element in the universe, was missing, and no helium was detected.
There was, however, strong evidence for silicon and sulfur, which allowed Quimby to uniquely classify PS1-10afx as a Type Ia supernova. Given the redshift, which was set first by matching the broad
spectral features to templates and second by narrow lines from the host galaxy, the broad band colors
of PS1-10afx were consistent with those expected from a Type Ia supernova as well, and these colors
evolved over time just as expected. To Quimby’s team, this left just one explanation: PS1-10afx was anormal Type Ia supernova, but it was simply 30 times brighter than it should be. There was only one
straightforward way to explain this.
The physics of Type Ia supernovae has been studied in detail over the past three decades, and there
is no known way to produce a Type Ia supernova with normal colors and a normal light curve but a
substantially higher luminosity. Generally, the rare supernovae that have been found to shine brighter
than Type Ia usually have higher temperatures (bluer colors) and larger physical sizes (and thus slower
light curves). New physics would thus be required to explain PS1-10afx as an intrinsically luminous
supernova. However, Quimby’s team found a second explanation that required only well demonstrated
physics: gravitational lensing. If there was a massive body in front of PS1-10afx, it could warp spacetime to form up to four magnified images of the supernova. If these were close enough together to appear as a single source in the survey, the total magnification would explain the anomalous brightness
of PS1-10afx.
Although the available observations were consistent with the hypothesis of Quimby’s team, there was
one glaring omission that led some to question their solution: where was the lens galaxy? The existing data clearly showed the presence of the supernova’s host galaxy, but there was no evidence for theneeded foreground galaxy. Last September, Quimby’s team set out to find the hidden lens. Using the
Low-Resolution Imaging Spectrograph on the 10 meter Keck-I telescope, they spent 7 hours collecting
light at the location of PS1-10afx, which had by then faded away itself (see figure 1). After carefully
extracting the signal from the data, Quimby’s team had their confirmation. Buried in the glare of therelatively bright host galaxy was a second, foreground galaxy (see figure 2). This second galaxy wasfaint enough to have previously gone unnoticed, but the analysis of Quimby’s team showed that it was
still the right size to explain the gravitational lensing of PS1-10afx.

Quimby’s team was formed at Kavil IPMU last year in response to a puzzling discovery: a supernova,
named PS1-10afx, was found with the colors and photometric rise and fall of a normal Type Ia supernova, but its peak brightness was 30 times greater than expected. Type Ia supernova are known to be
standardizable candles – objects with a known luminosity – and have famously been employed to reveal the accelerating expansion of our universe. PS1-10afx’s anonymously bright appearance led someto conclude that it was not at Type Ia supernova at all but rather a completely new type of superluminous supernova. But to Quimby’s team, the resemblance to normal Type Ia supernovae shone through.

Robert Quimby
A team of researchers led by Robert Quimby at the Kavli Institute for the Physics and Mathematicsof the Universe has announced the discovery of a galaxy that magnified a background, Type Ia supernova through gravitational lensing. The discovery confirms the team’s previous explanation for the unusual properties of this supernova. The team has further shown how such discoveries can be made far
more common than previously thought possible. Type Ia supernova seen through gravitational lenses
can be used to make a direct measurement of the universe’s expansion rate (the Hubble parameter), so
this discovery may have a significant impact on how cosmic expansion is studied in the future.

Detection of the gravitationallens magnifying a Type Ia supernova

The small size of this lens galaxy and the large magnification it produced were not exactly what theexperts would have predicted for the first discovery of a gravitationally lensed Type Ia supernova,
but they may very well be typical of discoveries to come. Because the likelihood of lensing increases
quickly with redshift, and the Type Ia production rate also increase with redshift, it turns out to be
more probable to find a highly magnified, high-redshift Type Ia supernova than a less magnified,lower-redshift one. A consequence of this is that most of the gravitationally lensed Type Ia supernovae
that will be found with searches such as the coming Large Synoptic Survey Telescope can be identified by their colors, the higher redshift, gravitationally lensed supernovae being redder than the more
nearby, un-lensed objects. This means that the survey need not resolve the individual image components, which enables more low-mass galaxies to serve as foreground lens and, over-all, increases the
expected number of gravitationally lensed Type Ia supernovae by an order of magnitude.
In the future, when a target is identified as a possible lensed Type Ia supernova, high-resolution follow-up observations can be taken to resolve the individual image components. If the angles and timedelays between each component can be measured, a direct test of cosmic expansion is possible. Each
image comes from the same source but travels a different path length on its way to the observer, so
the universe has more time to expand over the longer path. This adds an additional phase delay. By
timing the delays precisely and comparing these to the delay expected from the geometry of the lens,the Hubble parameter can be inferred without a distance ladder. The discovery and selection method
crafted by Quimby’s team may thus soon improve our understanding of our expanding universe.

Its Cosmological Implications”
The Kavli-IPMU mini-workshop on “Massive Gravity and Its Cosmological Implications” was heldfrom April 8th to April 10th, and brought together
researchers interested in the theoretical and observational aspects of modified gravity, specifically themassive gravity theory. A total of 36 participants
attended the workshop, reporting on 12 active contributions in the form of oral presentation.

such as a partially massless theory, which can avoid
some of the observational bounds. The talk by
Keisuke Izumi addressed the recent concerns on thecausality in the theory in comforting way, pointing
out inconsistencies in the arguments. The day was
concluded by Robert Caldwell’s positive talk on newobservational signatures of non-linear effects arisingfrom massive gravity.

Gravitation remains the most mysterious among thefour known fundamental forces in nature. Although
General Theory of Relativity has been in perfectagreement with experiments and observations, we
do not really know how gravity behaves at distances
shorter than hundredth of a millimeter or at distances of the order of the size of the observable universe.
Thus, it is natural to ask whether gravity can be
modified at these distances in a theoretically controllable and experimentally viable way. The large distance modifications are especially attractive, since
it is expected that they may provide an alternative
explanation for the current accelerated expansion of
the universe. Massive gravity and its extensions haverecently become one of the popular candidates inthis direction.

The second day was mostly dedicated to the solutions. Mikhail Volkov, Emir Gumrukcuoglu andChunshan Lin presented their work on cosmologicaland black hole solutions in various versions of thetheory. In the framework of the simplest version of
the theory, difficulties in getting stable universe solutions were pointed out, while several approaches
in curing them were proposed and discussed. In thecontext of extended theories, Tsutomu Kobayashi
and Rampei Kimura discussed the mechanism forscreening of the modifications at observable scales.
The session was concluded by Tetsuya Shiromizu,
who shared his concern on the ground state of spacetimes with/without black holes.

The goal of the workshop was to bring together theleading researchers in this field, allowing them toshare their contributions in the conference-formtalks, and exchange ideas in the lengthy discussion
sessions. The first day of the workshop focused on
the theoretical aspects of massive gravity. CedricDeffayet emphasized the subtle problems associatedwith the usual construction of the theory and introduced alternative formalisms which may overcome
some of these. Fawad Hassan explored the connection between the bi-metric theories (which are two
metric extensions of massive gravity) with someknown modified gravity models. These connections
can then be exploited to obtain healthy reductions,

The third day was devoted to two talks by Kei-ichi
Maeda and Jiro Soda, on anisotropic solutions in
the bi-metric theory. Although any anisotropies get
diluted, the rate of the decrease was found to be
slower than in standard general relativity, opening
up possibilities for observational signatures. The
afternoon session was devoted to discussions; after
the summary talk by Shinji Mukohyama, Kei-ichi
Maeda moderated a discussion session in which thecurrent theoretical development and challenges thatlie ahead was actively discussed.
The discussions in the sessions, as well as in thegenerous breaks proved to be essential to guide theresearch directions of the participants and initiate

Kavli IPMU Annual Report 2013

The Kavli IPMU “MaNGA Focus Week” concluded
with great success on Friday, May 24th. MaNGA
stands for “Mapping Nearby Galaxies at Apache
Point Observatory,” a new Sloan Digital Sky Surveythat will begin in 2014 and run for six years with theaim to obtain resolved spectroscopy for an unprecedented sample of 10,000 nearby galaxies. (See, Kavli
IPMU News No. 20, pp. 16–17.) Kavli IPMU’s own
Kevin Bundy is the Principal Investigator. The focus
week served not only as an all-hands team meeting
designed to advance preparations for the project but
also as the Critical Design Review of the MaNGA
instrumentation upgrades that are being planned for
the Sloan 2.5 m telescope.

The review committee was highly impressed withthe team’s preparation and mature design, the resultof an impressive and rapid effort over the last 14
months. They recommended the project proceed on
track to full production and deployment in August
2014. At the same time, they helpfully identified apotential weak point in the quality of skyline subtraction that MaNGA hopes to achieve, an issue thatthe team is now aggressively addressing. With thispositive feedback from the review, MaNGA can lookforward to the first of its IFUs being constructed
over the summer of 2013, and the first of ultimately
six “cartridges” of MaNGA hardware ready for testing at the observatory in February 2014.

An external committee of prominent experts reviewed over 200 pages of original material developed by the MaNGA team and evaluated presentations on aspects of the project that ranged fromthe hardware design to the observing strategy andsoftware tools. The primary focus was a new type of“integral field unit” (IFU) design innovated by the
MaNGA team, which combines up to 127 opticalfibers into a tightly packed and highly regular hexagonal array. The team demonstrated through results
both in the lab and with prototypes taken on sky that
their design could regularly achieve the theoreticalmaximum throughput of 96% in a cost-effective
solution that integrates seamlessly into the existing
infrastructure at Apache Point Observatory.

Also discussed were MaNGA’s next steps which
include refinements to the sample selection and observing strategy as well as the development of software analysis tools which are crucial for providing
data products that will eventually be released to the
public. For each of the 10,000 galaxies in the sample,
MaNGA will provide maps of the internal propertiesof stars and gas as well as the velocity fields of bothconstituents. This information will provide valuable
new constraints on the life cycle of galaxies, including the physical processes that regulate their birth,
continued growth at late times, and their “death”
through the cessation of star formation. The ability
to use velocity maps to “weigh” galaxy components
will also constrain the amount of dark matter in galaxies and possibly provide tests of the dark matter
profile shape and alternate gravity theories.

Collider Physics

The Kavli IPMU School on the Future of Collider
Physics was successfully conducted during July
16–19, 2013. Having a school dedicated to the future
prospects of collider physics was a very timely idea
for three main reasons: the recent discovery of a
Higgs-like boson at the CERN Large Hadron Collider (LHC) and the subsequent measurement of someof its properties in the early LHC run, the promise ofgathering a wealth of new information on the Higgs
in the next runs of the upgraded LHC, and finally,
the prospects of having an International Linear Collider (ILC) in the near future as a Higgs factory anda precision machine. All of the three broad areas
were covered at great depth in the school, which
included 12 lectures by leading experts in the field,
one poster presentation session by the participants
and a panel discussion session on the big questions
and promising directions in this subject.
It was no surprise that most of the lecturers focusedon different aspects of Higgs physics, with topics
ranging from an effective field theory framework
to parametrize the deviations of Higgs properties
from the Standard Model and the current status ofits measurements, to important concepts in statistics
necessary to properly interpret the data presented
by the ATLAS and CMS collaborations. The current status of theoretical calculation of Higgs cross-sections, the next-to-leading order event generatorsand future goals in improving the higher order QCD
calculations and parton distribution functions werealso reviewed. New techniques in top quark physics
were discussed as well, which might prove to be crucial in new physics search at the LHC.

The school was kick-started by an opening lecture by
Kavli IPMU Director Hitoshi Murayama, where hegave a broad overview of the physics behind a highprecision machine like the proposed ILC with its associated challenges, and the accuracy with which it
can determine the properties of new particles at the
weak scale including the Higgs boson. Hitoshi also
informed us about the current status of Japan hosting the ILC in the near future. This was followed
up in the subsequent days with very thorough talks
by experimentalists on the high-luminosity LHC
programme and details on the ILC accelerator anddetector developments and physics goals.
The participants included around 45 graduate students and postdocs from all over Asia, most of them
being from Japan, India, South Korea, Taiwan, andChina. They also presented their recent work in a
poster session, during which very intense and lively
discussions took place.

be used to learn about galaxy formation phenomenologically, and simultaneously learn about thecosmological parameters. Numerical simulations ofcold dark matter are the workhorse for cosmologicalstudies from small-scale structure. The second day
focused on the accuracy and large volume requirements on numerical simulations. The third day was
devoted to the topic of redshift space distortions,which reflect our inability to measure the exact positions of galaxies due to their motions. There was a
discussion on the progress in modelling these distortions. The fourth day examined how baryonic processes can cause a back-reaction on the dark matterand understanding parameters that can capture theseprocesses. This is essential to exploit the statistical power of measurements of cosmic shear which
several ongoing and large upcoming surveys will
provide. There was also a discussion on modifications to gravity, novel probes on large scales, and theensemble of simulations of specific modifications togravity currently available. The last day was devoted
to identification of galaxy clusters in large imaging
surveys, and their use as probes of cosmological parameters.
The last day also featured two summaries of theworkshop, an optimist’s summary delivered by Frankvan den Bosch and a skeptic’s summary delivered byMartin White. The optimist’s summary presented
some of the difficulties in modeling of small scale
structure that were discussed during the workshop,
but also showed that these small scale probes are
significantly constraining even after marginalization
over a large number of galaxy formation and modeling uncertainties. It also highlighted the current
tension between cosmological parameters obtained
from the cosmic microwave background experiment
Planck, and a number of small-scale structure probes
on the matter density and the amplitude of density
fluctuations in the Universe. The skeptic’s summary
included a parallel to collider experiments in particle
physics. The suggestion was that precision measurements of cosmological parameter should perhaps beleft to clean probes such as baryon acoustic oscillation experiments or CMB experiments (analogous toelectron machines in particle physics), while small
scale structure probes (analogous to proton machines) are excellent tools for discovery than precision. It highlighted the importance of demonstrating
the resilience of small scale probes to uncertainties
in galaxy formation physics. It also suggested theneed to perform sensitivity studies (some ideas discussed during the workshop), to help design observational campaigns in the future.

European Union’s UNIFY Workshop

Hirosi Ooguri (Kavli IPMU / Caltech )Since 2011, the Kavli IPMU has been participatingin the research program entitled, “Unification of
Fundamental Forces and Applications (UNIFY),”
under the International Research Staff Exchange
Scheme of the Marie Curie Actions of the European
Union (EU). There are three nodes in the UNIFY
network in Europe: the Berlin node consisting of
Humboldt University and the Max-Planck Institutefor Gravitation Physics, the Paris node with the École
Normale Supérieure, the University of Paris VI, andthe Centre de Saclay of the French Atomic Energy
Commission, and the Portuguese node with the University of Porto. Non-EU nodes in the network are at
the California Institute of Technology and the Stony
Brook University in the United States and the Perimeter Institute of Canada, as well as the Kavli IPMU.
The purpose of the program is to enhance exchanges
and collaborations among researchers in the UNIFY
network. The Marie Curie Programs cover the travel
expenses of EU researchers when they visit non-EU
nodes. The research objectives of the programs arefundamental aspects of superstring theory and quantum field theory toward understanding the unification of forces in nature. Hirosi Ooguri represents the
Kavli IPMU as a member of the executive board of
the UNIFY network.
Over the past 3 years, several collaborations haveemerged within the UNIFY network. Every summer, the network hosts its main conference. The firstmain conference was held at the University of Porto
in 2011, followed by the second main conference inBerlin in 2012. This summer, the third meeting was

held at the Kavli IPMU. For two weeks from August
26 to September 6, the Kavli IPMU hosted the UNIFY workshop entitled, the “Kavli IPMU Workshop
on Gauge and String Theory.”
Unlike regular research conferences, we only scheduled a two hour talk for each morning, leaving afternoons for informal discussions and collaborations,to enhance exchanges and collaborations within the
UNIFY network. This followed the successful styleof workshops practiced at the Aspen Center for Physics for more than 50 years. In fact, several research
results have emerged from collaborations during theworkshop.
The first week of the workshop was dedicated to theintegrability structure of the AdS/CFT correspondence, and the second week, to exact techniques suchas localization in supersymmetric gauge theories.

Approximately 50 researchers from Europe came toparticipate in the workshop, some of whom stayed at
the Kavli IPMU for a few months and contributed to
its research activities. Most of the researchers fromabroad were supported by EU’s Marie Curie Action,and the total cost for the Kavli IPMU was about halfof its regular Focus Week.
Though the workshop turned out to be larger thanwe originally anticipated, it was very successful. We

Holography and QCD—Recent Progress

and Challenges—
In the late 1990’s, a mysterious duality called the“gauge/string duality” was discovered out of theresearch in string theory. The claim is that a gauge
theory and string theory in a certain curved spacetime can be physically equivalent. This duality isalso called the “holographic dual,” because it is aduality relating two theories in different space-time
dimensions. From about 10 years ago, the applicationof this idea to QCD, which is the theory of strong interaction, has been discussed extensively. This workshop, held on September 24–28, is mainly focusedon topics related to the research in this direction.

It has been shown that this new technology to analyze QCD using the holographic dual provides very
useful and powerful tools to analyze the propertiesof hadrons and QCD, such as spectrum and interactions of hadrons, QCD phase structure, propertiesof quark gluon plasma realized at high temperature,and so on. In particular, one of the advantages of thisapproach is that it can be applied to the systems withtime evolution and/or chemical potential, for which
other non-perturbative methods like lattice QCD are
not useful enough. In fact, it has attracted the attention of hadron physicists as well as string theorists
and there have been fruitful interdisciplinary collaborations between string theorists and hadron physicists. One of the successes of the workshop was that
we were able to gather together experts of both fields

around the world, providing a good opportunity tointeract with each other. There were many string
theorists showing results in hadron physics and hadron theorists using holography and string theory. It
was impressive to see that they were discussing anddebating together toward common goals without aserious language barrier.
The topics discussed in the workshop include, calculations of hadron masses including the effects ofelectro-magnetic interactions, analysis in the Veneziano limit of QCD, descriptions of heavy hadrons,
research on the systems with time evolutions thatare aimed toward the application to the experiments of heavy ion collisions in RHIC and LHC,
study of quark gluon plasma, various phenomena in
the presence of strong electric and magnetic fields,
phase structure with finite temperature and chemical
potential, and so on. There were 25 talks in 5 days,
and a lot of new interesting results on various topics
related to holography and QCD were reported.

Symposium on Gravity and Light

An international workshop called "Symposium on
Gravity and Light" was held at the Kavli IPMU forfour days, September 30 to October 3, 2013.
Light is our main source of information about the
distant, early universe—indeed, until gravitational
waves and extragalactic neutrinos can be observed
directly and routinely, it is the only source. So inorder to study the origin and evolution of the universe, it is fundamentally important to understandlight propagation in spacetime under the influence ofgravity alone, even before taking into account otherastrophysical effects such as absorption. Hence, thisworkshop was dedicated to gravitational optics in a
broad sense.
Black hole spacetimes were a major theme since theinfluence of gravity on light is, of course, seen mostclearly when it is strong. Starting with optical geometry and the Gauss-Bonnet method (Marcus Werner), we discussed stable photon orbits, which areanalogous to “whispering galleries” (Gary Gibbons),
extreme trapping horizons of black holes (Tetsuya
Shiromizu), and the properties and observabilityof black hole shadows (Kei-ichi Maeda and Volker
Perlick).
Since the optical geometry of rotating Kerr black
holes has Randers-Finsler structure, more generalmathematical results on geodesics (Erasmo Caponio
and Ricardo Gallego Torromé) and Killing vectors(Takayoshi Ootsuka) in Finsler geometry were pre-60

lensing theory were also considered, in particular
universal magnification invariants for ADE singularities (Amir Aazami), and magnification relations
for perturbed singular isothermal quadrupole lenses(Zhe Chu).
Testing cosmology with gravitational lensing wasanother major theme and included a review of therecent controversy about the rôle of the cosmological constant in light bending (Masumi Kasai), lenses
with negative convergence, which may be used as
effective models for cosmic voids (Hideki Asada),
as well as tests of the homogeneity postulate andobservational prospects (Jean-Philippe Uzan). We
also discussed the underlying gravity theory, in particular inflation (Misao Sasaki), and a new geometrodynamical framework to derive gravity actions,in which light dispersion relations are fundamental(Frederic Schuller).

Neutrino oscillation, discovered by the Super-Kamiokande collaboration in 1998, is the first evidenceof the physics beyond the standard model of particle
physics. Over more than a decade since then, thestudies of neutrino oscillations have grown to be oneof the central topics in particle physics. As yet, wehave not reached full understanding of what neutrinos are telling us.
During 2011–2012, the discoveries of the electron
neutrino appearance by the T2K experiment, towhich the Kavli IPMU participates, and antineutrino disappearance by the three reactor experiments
opened the door to the next stage. The determinationof the last mixing angle θ 13 with those experiments
made it possible to approach the major goals of neutrino physics, search for CP asymmetry in neutrino
sector, and determination of the mass hierarchy, inthe near future.
Because of the tiny interaction probability, the instruments to detect and study neutrinos tend to behuge, like the Super-Kamiokande detector that uses
50,000 tons of pure water. In order to further advance the study of neutrino properties, next generation detectors with larger target mass and better performance have been intensively studied all over theworld. In Japan, the Hyper-Kamiokande, a 1 megaton water Cherenkov detector, is proposed as the62

SUSY: Model-Building and Phenomenology

Koichi Hamguchi (U. Tokyo)
Junji Hisano (Nagoya U.)
Masahiro Ibe (ICRR, U. Tokyo)

The workshop “SUSY: Model-Building and Phenomenology” was successfully conducted at the Kavli
IPMU during December 2–4, 2013. Having a workshop dedicated to current situations and future prospects of supersymmetry (SUSY) model-buildings
and their phenomenological studies was the mostimportant and timely idea because of the following
reasons. First, the recent discovery of a new bosonand subsequent measurements of its properties at the
CERN Large Hadron Collider experiment (LHC) indicates that the boson seems strongly to be the Higgs
boson predicted by the standard model (SM). Next,
no new physics signals, on the other hand, have been
discovered at LHC, which provides very stringent
constraints on SUSY models. Finally, no robust newphysics signals have been detected at dark matter
detection and flavor-related experiments, either. Because of the reasons, many SUSY models proposed
before LHC were ruled out and people were required
to build new SUSY models which are consistent with
the new experimental results with taking care of thenaturalness problem concerning the electroweak
scale.
All of these issues were covered in great depth in theworkshop, which included twelve plenary talks andseven contributed (short) talks. The workshop waslaunched by an opening talk by Kavli IPMU Director Hitoshi Murayama, where he gave a broad over-64

view of the physics concerning new physics (SUSY)
models. This was followed up with subsequent thorough talks by Graham Ross on several known SUSY
models with focusing carefully on the fine-tuning
problem, by Norimi Yokozaki on the focus-point
scenario, by Philipp Kant on three-loop Higgs masscalculation in MSSM, by Joshua Ruderman on highscale SUSY model, by Tomer Volansky on R-parity
violating scenario, by Fuminobu Takahashi on SUSY
cosmology, and by Masahiro Ibe on the pure gravity
mediation model. There were also two experimental(ATLAS) talks by Shimpei Yamamoto and Naoko
Kanaya discussing the current status and future
prospects on SUSY searches at LHC. In addition,
attractive non-SUSY scenarios were presented by
Pyungwon Ko and Mikhail Shaposhnikov. Throughthe talks, participants could clearly understand thesituation of SUSY (and non-SUSY) model-buildings
and obtain a clue of promising future directions on
this subject.

Workshop on “Primitive Forms andRelated Subjects”

Primitive forms have been one of the subjects of the
Math-String seminar and Topological Strings seminar at the Kavli IPMU for the reason that the theoryof primitive forms is relevant for the complex geometric aspect (“B-model”) of the Landau-Ginzburgmodel whose superpotential is given by the function
F. According to a postulate, called mirror symmetry
in topological string theory, the theory should correspond to the symplectic geometric aspect (“A-model”)
of another theory, such as the Gromov-Witten theoryof a compact Kähler manifold or the Fan-Jarvis-Ruan-Witten theory (2007, 2013) of a Landau-Ginzburg
orbifold.
As a consequence of the theory, a primitive form induces the flat structure on the deformation parameter
space (i.e., a flat metric together with a ring structureon the tangent bundle of the parameter space satisfying some integrability conditions. The structure
was later axiomatized as the Frobenius manifold
structure by B. Dubrovin 1990). Then that structure
defines a potential function called the prepotential
on the parameter space. One mathematically rigorous formulation of the mirror symmetry conjectureasks that the prepotential function obtained froma primitive form should coincides with that of
the mirror side (i.e., of Gromov-Witten theory or of
FJRW theory) after a suitable identification called
the mirror map, of parameter spaces equippedwith the flat coordinates.
However, the verification of this mirror symmetry
conjecture was not achieved until recently, since eventhough primitive forms are theoretically known toexist, their explicit expression was not known except for two cases: universal unfoldings of simple
singularities and simple elliptic singularities (1983
K. Saito). Mirror symmetry for these two cases has
been confirmed rather recently (simple singularity
case, Fan-Jarvis-Ruan 2007, simple elliptic singularity case, Krawitz-Shen 2011, Milanov-Shen 2012).

Modeled on the classical theory of elliptic integrals

Mini-Workshop on “Massive Gravity and

Organizers

Supersymmetry is originally a notion in particle
physics describing the symmetry between two basic
classes of elementary particles: bosons, which havean integer valued spin; and fermions, which have ahalf integer valued spin. Supersymmetry is a recurring theme in theoretical physics to find a unified
description of the fields and forces of nature. On theother hand, supersymmetry is an interesting structure also from the purely mathematical viewpoint,
for example, as a natural and rich generalization ofclassical algebraic structures such as Lie algebras, or
as realizations via special types of spinor fields on
Riemannian or pseudo-Riemannian manifolds. The
last theme is also intimately connected with classicaland quantum field theories on curved spacetime withsupersymmetry, which have recently attracted interest among both physicists and mathematicians.
The purpose of the workshop was to promote interaction between physicists and mathematicians invarious aspects of supersymmetry. Among partici-

Peter Goddard Symposium

Hirosi Ooguri (Kavli IPMU / Caltech)

Professor Peter Goddard is a distinguished mathematical physicist. He formulated the quantizationof the relativistic string, proved the “no ghost theorem” of string theory, proposed the electromagnetic
duality in non-abelian gauge theory, and provided
remarkable evidences for it, introduced and studied
a class of conformal field theory, which has become
the foundation of our understanding of gauge symmetry in string theory. His seminal achievements inthese areas provide important examples for researchers at the Kavli IPMU, who try to open new avenuesof research at the interface between mathematics andphysics.

Professor Goddard has also contributed in creating and maintaining environments for researchers.
He played a leading role in establishing the Isaac
Newton Institute for Mathematical Sciences at Cambridge University, where he was the Deputy Director. He was the Master of St. John’s College, before
becoming the eighth Director of the Institute for Advanced Study in Princeton. He stepped down fromthe position in 2012 and is currently a professor at
the Institute.
Professor Goddard received the Dirac Prize andMedal from the International Center for Theoretical
Physics in Trieste and is a Fellow of the Royal Society of London and a Commander of the Order of the
British Empire.
Professor Goddard visited the Kavli IPMU in Marchand April, 2014. On this occasion, we organized aone-day symposium to celebrate his contribution inscience. Some of the faculty members and affiliatedmembers of the Kavli IPMU, who were visitors of
the Newton Institute and members of the Institutefor Advanced Study under his leadership, spoke at

The Symposium opened with a talk by Hitoshi Murayama, the Director of the Kavli IPMU, on his recent work on geometry of non-relativistic Goldstonebosons. This work generalizes Nambu’s work on
spontaneous symmetry breaking in nontrivial ways.
Tohru Eguchi of Rikkyo University spoke on the
Mathieu Moonshine, a joint work with Hirosi Ooguri
and Yuji Tachikawa of the Kavli IPMU. This work
originated from the work of Eguchi and Ooguri, 25
years ago, with Anne Taormina and Sung-Kil Yang.
21 years after this original work, a chance encounterof Eguchi with Ooguri and Tachikawa in 2010 led toa discovery of the remarkable connection between
K3 geometry and the largest Mathieu group M24.
Kentaro Hori of the Kavli IPMU also talked about
his PhD thesis published 20 years ago, which turned
out to have significant implications of current theoretical research. Yuji Tachikawa talked about instantons and string theory and Simeon Hellerman on
string theory of the Regge intercept. The Symposium

meeting program and presentation files are available
at the URL:
http://indico.ipmu.jp/indico/conferenceDisplay.py?ovw=True&confId=23

The number of participants was over 100 for both
meetings including foreign participants from Canada, France, Korea, Russia, Switzerland, UK, and US.
The meetings have been open to all interested scientists and community members and all presentation
slides are open to public. It is our firm intention to
make the Hyper-K project completely open to the international community and contribute to the worldwide effort to make future neutrino physics program
strong.
The goal of the meetings is to discuss the physics
potentials of Hyper-K, the design of the detector, andnecessary R&D items including cavern excavation,
tank liner material and its design, photo-sensors

and their support structure, DAQ electronics andcomputers, calibration systems, water purification
systems, software development, and so on. One of
big challenges of the detector is to excavate world
largest underground cavity and build 1 million ton
water tank in it. We made an optimal conceptual
design, corresponding construction schedule andcost estimation for them. The group aims to proceed to a full geological survey of the candidate site
for making a detailed design and start the detector
construction. A photo-sensor is also a key elementof the detector. It would be critical to develop cheapand high-performance sensors. It was reported thatnew photo-sensor development works in Japan and
US are going on schedule. New photo-sensors would
have 30% higher sensitivity and much better timing
resolution than the photomultipliers being used in
the Super-Kamiokande.

The meeting discussion extends to near neutrino
detectors to be located at 1–2 km away from theneutrino production target at the J-PARC. The detector, if we construct, would play a central role tounderstand the J-PARC neutrino beam property andneutrino-nucleus interactions both of which would
be indispensable to provide convincing results on CP
asymmetry. Extensive study on the near-detector design and relevant physics sensitivity is going on thesedays. In the 4th meeting, a team has been formed
for writing a letter-of-intent for the CP asymmetry
study.
Moreover, discussions were made on working grouporganization, international participations and their
responsibilities, and ongoing project prioritization
activities in Japan and other countries. The HyperKamiokande project is now in a turning point andthe working group members are accelerating theworks to define and realize the project.

The Kavli IPMU ran a booth, exhibiting its research activities, at the Super Science High SchoolStudents Fair 2013 held at Pacifico Yokohama on
August 7 and 8. Also, two young researchers working on the SuMIRe Project, Kavli IPMU AssistantProfessor Masamune Oguri and Postdoctral Fellow
Jun Nishizawa, jointly presented a mini lecture
entitled “Dark Universe ‘Seen’ with the Subaru
Telescope” on the second day. The mini lecture
was well attended by as many as 230 students, withmany of them standing. There were questions fromthe audience on many topics, including the future
prospects of research using the Subaru Telescopeand HSC, the lecturers’ motivations for becoming
researchers, and their high school days.

Science Agora 2013 was held on
November 9 and 10 at the National
Museum of Emerging Science andInnovation (Miraikan) in the Tokyo
waterfront region and all nine WPIcenters participated jointly. Morethan 6,000 people visited the two-day
event. At the “WPI Science Live!”booth where all the WPI centerspresented their scientific activities inrotation, the Kavli IPMU presented
a lecture by Associate Director Nobu
Katayama and a talk session by two
Assistant Professors in mathematics,
Satoshi Kondo and Tomoyuki Abe.
This “WPI Science Live!” booth wasselected as one of 11 programs thatreceived the Science Agora Award.

Another “Ask a Scientist Live!” session presented by Professor Shigeki Sugimoto and a “Digital Space Theater”
program attracted audiences. Graduate students explained
a variety of research programs at the Kavli IPMU using
posters and video clips. They also helped visitors in anexperimental program of making a spectrograph by hand.
A Japanese Kyogen performance by Kavli IPMU foreign
researchers got applause from the capacity audience in the

Workshop to Aim at Spreading Astronomy“The 9th Workshop to Aim at Spreading Astronomy” was held at the Kavli IPMU lecture hall on November 17–19, co-hosted by the Kavli IPMU and the National Astronomical Observatory of Japan (NAOJ).
This workshop has been held annually by NAOJ and partner institutions for those who are involved in
spreading astronomy at science museums, planetariums, and educational institutions. This year, a three-day
intensive course was given to the participant aiming at conveying the latest cosmology research to the many
people through them. Professor Masahiro Takada served as a coordinator and also gave a lecture. Lectures
were also given by Principal Investigators Naoshi Sugiyama and Mihoko Nojiri, Associate Professor Shinji
Mukohyama, Director of the Department of Phyrical Cosmology, Max Planck Institute for Astrophysics Eiichiro Komatsu, Professor Naoki Yoshida at the School of Science, the University of Tokyo, and Associate

Special Public Lecture by Fabiola Gianotti

WPI Joint Symposium

Dr. Fabiola Gianotti, former spokesperson of the ATLAS experiment that discovered the Higgs boson at
CERN, gave a special public lecture entitled “Higgs Boson and Our Life” at the Hama-Rikyu Asahi Hallon November 20. It was hosted by the Kavli IPMU and co-hosted by the Asahi Shimbun Company. This
lecture received much interest because of the announcement in the previous month that the 2013 Nobel
Prize in Physics would be awarded to theorists who predicted the Higgs boson. The lecture was also broadcast live with a worldwide audience of nearly 1,000. Fabiola gave her talk in English and it was translated
to Japanese by Kavli IPMU Director Hitoshi Murayama at short intervals. Mariko Takahashi, Senior Staff
Writer of the Asahi Shimbun Company, moderated the Q&A session. Her frank questions highlighted
Fabiola’s personality and pleased the audience very much.

On December 14, the Third Joint Symposium of the WPI centers entitled “Science Talk Live!” was heldat the Sendai International Center with participation of all the nine WPI centers. About 600 high school
students were invited from various places in the Tohoku region. Researchers at Tohoku University’s AIMR
(The Advanced Institute for Materials Research) and Directors of three new WPI centers, launched in 2012,
gave lectures. In addition, all nine WPI centers ran booths. At the Kavli IPMU booth, Director Murayama’svideo clip about the discovery of the Higgs boson was shown and Kavli IPMU’s research programs wereshowcased using posters and a demonstration using hand-made spectrographs.

On December 1, the 9th Kavli IPMU-ICRR Joint Public Lecture was held at the Koshiba Hall on the University of Tokyo’s Hongo Campus. ICRR Associate Professor Masahiro Ibe, who is also a Kavli IPMU
Scientist, gave the first lecture on “The Standard Model of Elementary Particles and the Higgs Boson.”
The second lecture was “Evolution of the Universe Probed by Means of Supernovae” by Ken’ichi Nomoto,a Principal Investigator of the Kavli IPMU. The lecturers nicely responded to the questions from many
people surrounding them at a science café-style discussion time after the lectures.

A winter science camp for high school students, “Open the Door to the Universe,” was held at the Kavli
IPMU for three days, December 25–27. Twenty students selected among applicants from all over Japan took
part. The science camp is one of the projects supported by the Japan Science and Technology Agency (JST),
providing hands-on experience to high school students. This was the third science camp held at the Kavli
IPMU. The participating high school students heard lectures from Kavli IPMU Professor Shigeki Sugimotoand other resea rchers on
forefront topics in theoreticaland experimental physics andin mathematics. They also attended Kavli IPMU’s teatime

session after the lecture

On January 25, the Kavli IPMU hosted another special lecture, “Knocking on Heaven’s Door,” delivered bya theoretical physicist Lisa Randall, Professor at Harvard University. She talked about the Higgs boson discovery at the CERN’s Large Hadron Collider (LHC) experiments from the viewpoint of a theoretical physicist. She also discussed topics ranging from the vast Universe to the tiny elementary particles it contains,
and their relations. Kavli IPMU Director Hitoshi Murayama interpreted this talk at short intervals, with
supplementary explanation. As Professor Randall is popular for her books for general audiences, the venue,
Koshiba Hall on the University of Tokyo’s Hongo campus, was full to capacity.

FIRST EXPO 2014
On February 28 and March 1, FIRST EXPO 2014 was held at Bellesalle Shinjuku Grand in Tokyo to present the outcomes of the FIRST (Funding Program for World-Leading Innovation R&D on Science andTechnology) to the general public at the end of the last year of the program. Kavli IPMU’s Director Hitoshi
Murayama’s SuMIRe (Subaru Measurement of Images and Redshifts)
project is one of the 30 selected projects in the FIRST program. From this
SuMIRe project, a full-scale replica of
the aspherical lens used in the Hyper
Suprime-Cam (HSC), an ultra-wide
field digital camera, was on display.
In addition, Kavli IPMU Professor
Masahiro Takada talked to the public
on the present status and the expected
outcome of the SuMIRe project on
February 28.

Science Program for Female High-School Students
The nine WPI institutes jointly participated in the 2014 AAAS (American Association for the Advancementof Science) Annual meeting, held on February 13–17 at the Hyatt Regency Chicago with the theme “Meeting
Global Challenges: Discovery and Innovation.” The nine WPI institutes hosted the WPI booth as a part of
the Japan pavilion organized by Japan Science and Technology Agency (JST), and held a one-hour workshop entitled “Build a Career in Japan!” jointly with RIKEN. In this workshop, Hideki Iwabuchi, Directorof Office for the Promotion of Basic Research, Basic Research Promotion Division, Research Promotion
Bureau, MEXT, introduced the WPI program, and Professor Petros Sofronis, Director of the International
Institute for Carbon-Neutral Energy Research (I2CNER), explained advanced and global research activities
at the WPI institutes.

On March 15, a program to encourage female students to study science, “Come Over to Learn the Universe!” was held at the Kavli IPMU, jointly hosted by the Kavli IPMU and the Institute for Cosmic Ray Research (ICRR), the University of Tokyo, and 35 high school and junior high school female students participated. This is a part of an attempt, planned by the University of Tokyo and supported by the Japan Scienceand Technology Agency (JST), to encourage female students to pursue careers in science by inspiring theirinterests in the field of science. The students listened to lectures given by two female researchers, Miho
Ishigaki (JSPS Postdoctoral Fellow at the Kavli IPMU) and Rieko Momose (Project Researcher at ICRR),
about their respective researches, and practiced laser interferometry, which is used in gravitational wave
telescopes, under the guidance of graduate students. Then the students had friendly talks with the lecturers
and graduate students at the Kavli IPMU’s interaction area.
