gram is attracting the best talents as ever. Several of our new members have turned down some of mostprestigious positions elsewhere. Our ongoing and future projects fascinate scientists around the globe.
Building an international institute from scratch was not easy. But thanks to the effort by our colleagues,
staff, the University, and MEXT, we got off the ground very quickly and incredibly well. Stay tuned
what we will discover in the next few years.

Our Mission
Our mission is very simple. Just like when you looked up the night sky when you were young, humanbeings are naturally drawn to basic and profound questions. Where do we come from? Where are wegoing? How did the Universe begin? Does it have an end? How does it work? The first step to answer
these questions is to understand what the Universe is made of.

At the Frontier

Director Hitoshi Murayama

We are making tremendous progress. David Spergel (PI) and Eiichiro Komatsu (Affiliate Senior Researcher) discovered that 96% of the Universe is unknown. Dark Matter, that makes up about a quarterof the Universe, is responsible for creating stars and galaxies in the Universe, that allowed the solar
system and us to be born. On the other hand, Dark Energy, about 70% of the Universe, is ripping ourUniverse apart. The history of the Universe has been based on the battle of these two titans. They are
the genomes of the Universe; many of our members are working together, just about to start a cosmic
genome project, using the Subaru telescope and many other experiments.

It is hard to believe now that this institute did not exist five and a half years ago. The building is buzzing with discussions, seminars, workshops, video meetings with US, Europe, or other parts of Asia, andabout a thousand visitors a year. And most importantly, the research at Kavli IPMU is producing results.
Yet we need to work further to become a permanent and mature institute.

We would not exist unless matter and anti-matter could be reshuffled at the level of one part in a billion. We need to find how matter and anti-matter can transform to each other. KamLAND-ZEN project,initiated by our Assistant Professor Alexandre Kozlov, currently has the world best limit on it. At thesame time, we need a new theory that combines science of the large (general relativity) and of the small(quantum mechanics), so that we can study what exactly the Big Bang was. Our Professor Kentaro Hori
has the most rigorous mathematical formulation to build such a theory.

The quest to solve the mysteries of the Universe is common for any culture, language, or ethnicity. Kavli
IPMU embodies this common quest. We have a very interesting spectrum of people. Experimentalists
and observers talk to the Universe directly, obtaining valuable data using instruments based on cuttingedge technology. Theorists act as interpreters trying to decipher messages from the Universe. This partof interplay is well-known. Yet we often lack the vocabulary to interpret such precious messages simply
because human language is based on our daily experience, not near the horizon of a black hole or when
the whole visible Universe was smaller than the size of an atom.
Mathematicians develop new vocabularies and grammars in a logically consistent fashion. Eugene
Wigner, a Nobel laureate in physics, once remarked about “the unreasonable effectiveness of mathematics in natural sciences.” Surely we benefit greatly from our mathematicians on site to formulate messages from the Universe into concrete theories. Then the process goes the other way. Precise mathematicalformulation of the problem allows theorists to make falsifiable predictions, which experimentalists andobservers take up as their next challenge to prove or disprove.
This coexistence of experimentalists, observers, theorists and mathematicians is unique among research
institutions on the planet. We believe we are poised to make breakthroughs using this combination oftalents. The world took notice. We are the best known institute among the five centers launched by the
WPI (World Premier International Research Center Initiative) program back in 2007. Our research pro-

This way, we are pushing the frontier of our knowledge in all possible directions.

Interdisciplinary ResearchInteraction among researchers from different disciplines is at the heart of Kavli IPMU. At daily tea time
at 3pm, scientists fire naïve and basic questions they were hesitant to ask during formal seminars. They
throw problems at each other asking for help. Many stay on till late in the afternoon discussing new
ideas they came up with during the tea time. The casual atmosphere promotes this kind of interactions.
Some of such interactions lead to research papers. We have seen mathematicians and physicists writing papers together, a very rare phenomenon. Astronomers and physicists work together for the next big
project. People even ventured to work with other areas such as condensed matter physics.

Systemic Reform and Globalization
Despite a high level of scientific research in Japan, there has been a sense that it was somewhat disconnected from the rest of the world. We have created a constant flow of scientists to and from Japan. It hashelped boost our visibility.

Kavli IPMU Annual Report 20123

Mission

At the same time, our science is completely global and also our membership. More than a half of ourscientific staff originated from other countries. This was made possible by reforming the traditional
systems at the University of Tokyo. We provide meticulous support for our scientists. For non-Japanese
members, we even support various aspects of life in Japan. We can offer competitive merit-based salaries. Split appointments with other institutions are now possible, yours truly being the first example.
The Kavli Foundation, a US foundation established by Mr. Fred Kavli, liked our cutting-edge scienceand global nature. They generously created endowment of seven and a half million dollars. This is our
first annual report from the Kavli Institute for the Physics and Mathematics of the Universe. This is thefirst time such a named institute was created at Japanese National Universities.

Starting with JFY 2012 the IPMU was renamed as the Kavli
Institute for the Physics and Mathematics of the Universe (theKavli IPMU) following a generous endowment from the Kavli Foundation. In commemoration of this, the Kavli IPMU
naming ceremony took place on May 10, 2012, at the Kavli
IPMU building, with Mr. Fred Kavli, Founder and Chairman of the Kavli Foundation, in attendance. IPMU Director
Hitoshi Murayama and President of the University of Tokyo
Junichi Hamada were the first speakers to open the ceremony.
President Hamada expressed gratitude to Mr. Kavli and offered his strong support for establishing the Kavli IPMU as apermanent entity of the University. Following the president’s
speech, Mr. Fred Kavli welcomed the IPMU as a member ofthe Kavli family and spoke about his philanthropic effort tosupport science. Then, congratulatory greetings were given by
distinguished guests, Dr. Robert Conn, President of The Kavli
Foundation, Dr. Hiroo Imura, Chairman of the WPI program,
Mr. Daisuke Yoshida, Director-General of Research Promotion
Bureau, MEXT, Roger Blandford from the Kavli Institute forParticle Astrophysics and Cosmology at Stanford University,
George Efstathiou from the Kavli Institute for Cosmology at
Cambridge University, Xiaowei Liu from the Kavli Institutefor Astronomy and Astrophysics at Peking University, and,
Yue-Liang Wu from the Kavli Institute for Theoretical Physics China at the Chinese Academy of Science. Also, a warmand encouraging message from Dr. Jonathan Dorfan, Presidentof the Okinawa Institute of Science and Technology Graduate
University, who unfortunately could not attend the ceremony,
was presented.
At the end of the ceremony, Director Murayama and Mr. Kavli
worked together to unveil the new Kavli IPMU sign in front of
the Kavli IPMU building. On the front and rear surfaces of thissign are inscribed the patterns representing sketches by Galileo
Galilei of Orion Nebula and Praesepe, respectively, depicted in
his book, Sidereus Nuncius, published in 1610. These patterns
shine in the night as seen in the picture.

Because our institute is supported by taxpayers’ money, we make special effort to bring back the excitement of science to the sponsors. We organize many public lectures and science cafés, produce quarterly
publications aimed at a general audience, some of us wrote popular science books. Fortunately, Japanese
media became very interested in what we do. Combined effort appears to raise awareness of scienceamong the general population, in particular among high-school and even younger students. As the success of the globalized world and technologically-advanced society hinges on educated and scientificallyminded workforce, we believe our effort is helping the society in the long run.

The day before the Kavli IPMU Naming Ceremony, May 9, Director Murayama and Mr.
Kavli, made a courtesy call on Prime Minister
Yoshihiko Noda, accompanied by Dr. RobertConn, Professor Sadanori Okamura, Presidentof the Astronomical Society of Japan, and Dr.
Naotaka Suzuki, Staff Scientist at the Lawrence
Berkeley National Laboratory. Together with thePrime Minister, Minister Hirofumi Hirano of
the Ministry of Education, Culture, Sports, Science, and Technology (MEXT) attended fromthe government.

Later, the University of Tokyo presented the2012 “Shokumon Award” to Mr. Fred Kavli.
The Shokumon Award was instituted in 2002 torecognize and thank individuals, corporations,or organizations that made major contributions to the growth of the University programs
through private donations, volunteer work andsupport, establishment of endowed chairs, or
research centers. “Shokumon” is the name of thecastle gate in the capital of the ancient Chinesestate Qi during the civil war era (403-221 B.C.).
Under King Wei (356-320 B.C.) and King Xuan
(319-300 B.C.), the state treated academics very
well, which brought the best minds to the capital
Linzi of Qi and led to a flourishing of academic
activities. The award is named after this history.
The prize was awarded to Mr. Kavli in recognition of the fact that annual returns in perpetuity
from the endowment established by the donationfrom The Kavli Foundation will help sustain the
Kavli IPMU as a permanent research institutewithin the University of Tokyo, and also that
this is a major contribution to the Universityof Tokyo in striving toward a new vision of thenational university. Mr. Kavli is the first international recipient of this award. The award
ceremony was held on October 2 at Ito Hall on
the University’s Hongo campus. From The Kavli
Foundation, President Robert Conn attended the
ceremony on behalf of Mr. Fred Kavli.

Kavli IPMU Annual Report 2012

On October 19, researchers and staff of the Kavli IPMU gathered and celebrated the 5th anniversary at the institute’s Research Building. During these five years since it was launched fromscratch on the University of Tokyo’s Kashiwa
campus on October 1, 2007, the IPMU has been
attracting topnotch researchers from all over theworld, producing a number of excellent scientificachievements, and increasing its international
visibility. As a result, the IPMU was given thehighest grade of “S” (superior) in the WPI Interim Review, which was carried out in 2011.
Together with the completion of the IPMU Research Building in December 2009, admission tomembership in the newly established TODIAS(Todai Institutes for Advanced Study) in January
2011, and becoming the Kavli IPMU by obtaining an endowment from the Kavli Foundation,
the IPMU has achieved a great step forward.
A noteworthy progress in the Kavli IPMU’s
research program in observational astronomy is
the first light of the Hyper Suprime-Cam (HSC),
the new-generation prime-focus camera of the
Subaru telescope that is designed to have a
1.5-degree field-of-view in diameter, substantially wider than the current camera (Suprime-Cam)by a factor of 7, but to maintain excellent image
quality. HSC is a “huge” digital camera, standing 3 meters high, weighing 3 tons, and having
116 CCD chips mounted at the focal plane, 870
million pixels in total. It has been developedby the joint efforts of National Astronomical
Observatory of Japan (NAOJ), the Kavli IPMU,
and other partners. At the Kavli IPMU, HSC has
been developed as one of the two subprojectsof the SuMIRe 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. The installation of the
HSC onto the NAOJ’s 8.2m Subaru Telescope in
Hawaii took place on August 16-17, 2012, and its
engineering first light was successfully achieved
starting from the night of August 28. It was confirmed that the HSC camera properly captured
lights from the star Vega. It was the exciting
moment that the HSC project finally became a
reality. Thanks to its large mirror aperture, wide
field-of-view, and excellent image quality, theHSC becomes the most powerful survey imaging
camera in the world. The HSC survey is planned
to start from the middle of 2013, for 5 years duration.

symmetry and other new physics possibilities at
SuperKEKB, a high-luminosity electron-positron collider at the High Energy Accelerator Research Organization (KEK) in Tsukuba, Japan.
The experiment is being prepared by an international collaboration with approximately 400
researchers from 15 countries, and will start in2014. The Kavli IPMU team will participate inboth detector construction and physics analysis.
Important responsibilities of the Kavli IPMU in
Belle II includes establishment of a super-precise
assembly procedure of a silicon vertex detector,
which determines decay vertices of B mesons in
the precision of less than 100 micrometers.

Introduction

Introduction

At the end of JFY 2012, the Kavli IPMU has atotal of 236 core researchers including principal
investigators, faculty members, postdoctoral fellows, affiliate members, long-term visitors, andgraduate students. Their research activities aresupported by 38 administrative and researchsupport staff. Besides the core researchers, many
short-term visitors visit the Kavli IPMU. The
number of scientific papers published in refereed
journals in JFY 2012 amounted to 352.

Another important milestone of the Kavli
IPMU’s efforts to address fundamental questions of the universe is participation in the BelleII experiment in November, 2012. This is important for the Kavli IPMU because full-time
researcher in the field of accelerator-based highenergy physics had been missing since its establishment, though the mission of the institute has
to be pursued through assault on three fronts,
namely underground, sky, and accelerator, tiedwith theoretical physics and mathematics. The
Belle II experiment aims at investigating super-

Executive Board

The Kavli IPMU has a rather unique organization. While research is conducted in a flat-structure manner with loosely defined grouping, thedecision making is done in a top-down scheme
under the Director’s strong leadership. This
scheme minimizes the administrative load forthe researchers. It is also intended to maximally
extract young researcher’s creative and challenging minds as well as to encourage daily crossdisciplinary interactions.
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 otherhiring 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 hold the Executive Board (EB) regularly toensure smooth operation of the Institute. The EB
has direct access to the Office of the President
for consultations on both scientific and administrative matters.

The main laboratory building on the Kashiwa
Campus provides a basis for our researchers.
Even most of experimentalists who are involvedin 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 Kamioka
experiments. The Berkeley Satellite, besides
being a place for research, 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 wellas with other departments within the Universityof Tokyo.

Einstein’s theory of relativity unifies a 3-dimensional space and a 1-dimensional time as a spacetimeand describes gravity as a fabric of curved spacetime. This picture has been very successful in explaining and predicting many gravitational phenomena. Experimentally, however, we do not know how gravity behaves at distances shorter than 0.01 mm. At shorter distances, gravity may behave completely differently from what we expect. For example there may be hidden dimensions at short distances. In fact,many theories, including superstring theories and Mtheory, require the existence of such extra dimensions.
Extra dimensions may exist everywhere in our universe,
but they are somehow hidden from us. One possibility
recently investigated very actively is called the braneworld scenario. In this scenario our universe is supposed to be a 3-dimensional surface, called brane, floating in higher-dimensional space. Although we cannot
see extra-dimensions directly, we may hope to detectsome indirect evidence of extra-dimensions in highenergy experiments or cosmological observations.
Gravity at very long distances (for example, billions oflight-years) may also be as weird as at short distances.
Precision observational data recently revealed that the
expansion of our universe is accelerating. If Einstein’s
theory is correct, this requires that more than 70% of
our universe is filled with invisible, negative pressure,energy. This energy is named dark energy, but we do
not know what it really is. This situation reminds us ofa story in the 19th century: when the perihelion shift of
Mercury was discovered, some people hypothesized theexistence of an invisible planet called Vulcan, a so-tospeak dark planet, to explain the anomalous behaviorof Mercury. However, as we all know, the dark planet
was not real and the correct explanation was to change
gravity, from Newton’s theory to Einstein’s. With this inmind, the Alternative Gravity Theories Group wonder
if Einstein’s theory at long distances can be changed toaddress the mystery of dark energy.

High-energy phenomena naturally occurring in the universe provide a wealth of data and new valuable
insights into particle physics and cosmology. The Kavli IPMU researchers use the universe as a laboratory
for testing new theories of dark matter and new physics beyond the Standard Model, and for understanding
the basic properties of the universe. In the past year, several exciting developments in particle astrophysics
were initiated by the Kavli IPMU members.
Dark Matter
Its existence is supported by a substantial body of astrophysical evidence, but
the identity of the dark matter particle(or particles) remains a mystery. Since
one does not know the interactions ofdark matter particles, besides their gravitational interactions, one must pursue a
broad range of possibilities.
Dark matter plays a crucial role in formation of cosmic structures, such as
galaxies, clusters of galaxies, etc. Astronomical observations of such structureson the largest scales have helped one
narrow down the possibilities for darkmatter particles. Ongoing astronomical

ditional clues regarding the physicalproperties of dark matter. The interdisciplinary nature of the Kavli IPMU
makes it a perfect place for a multi-faceted, comprehensive effort to understand dark matter from both theastrophysical side and the particle physics side. Kamada and Yoshida, and their collaborators, studied how
the structures on the scales smaller than a galaxy would be affected by the so called warm dark matter inthe form of, e.g., sterile neutrinos. At the same time, Ibe, Kamada, and Matsumoto explored the signaturesof non-thermally produced supersymmetric dark matter on the cosmic structures.
In another example of synergy between particle physics and astrophysics, Loewenstein, Kusenko, andYanagida have proposed a new dark matter candidate and conducted a search for this form of dark matter using some dedicated observations with Suzaku, a Japanese X-ray telescope in space. Light scalar fields called
moduli arise from a variety of different models involving supersymmetry and string theory, and they present
a formidable, long-standing problem for cosmology: generically, they appear to dominate dramatically over

An intriguing possibility is that both dark matter and ordinary matter arise from the same process inthe early universe, in which supersymmetric fields form a condensate that splits into lumps called Qballs, which play an important role in generating a population of dark matter particles, as well as matterantimatter asymmetry of the universe. The common origin of dark matter and ordinary matter may be thekey for understanding why the amounts of the two types of matter in the universe are not very different.
This appealing scenario has led Kamada, Kawasaki, and Yamada to predict that dark matter could be thesupersymmetric partner of the W boson.

Henning and Murayama have examined the effects of relic dark matter annihilations on the predictionsof big bang nucleosynthesis, which can be a sensitive probe of new physics. Annihilation of dark matterparticles with a relatively low mass can disrupt the formation of nuclei in the early universe. Henning and
Murayama derived some very strong constrains on the properties of dark-matter particles, which help narrow down the range of possibilities.
Bhattacherjee, Choudhury, Harigaya, Matsumoto, and Nojiri performed a model independent analysis ofdark matter interactions with quarks, addressing an issue that is important for searching for dark-matterparticles at Large Hadron Collider.
Black holes, big and small
The appealing possibility that black holes can form in the early universe was investigated by Kawasaki,
Kitajima, and Yanagida. Curvaton cosmology can produce black holes with different masses. Black holes
with masses ∼ 1020 – 1038 g can account for dark matter in the universe, while more massive black holes,
about 105 solar masses, can serve as seeds of supermassive black holes observed in the centers of galaxies,
including Milky Way.

The LHC experiment enables us to systematically investigate the electroweak
symmetry breaking, to study quantum
chromodynamics (QCD), and to probe
new physics beyond the SM. Among several researches of collider phenomenology, most of the members in the group are
studying physics beyond the SM such as

The largest supermassive black holes, with masses of hundred million solar masses and beyond, are themost powerful sources of radiation in the universe. These giant black holes absorb gas and stellar matter inthe centers of active galaxies, spewing very high energy gamma rays and cosmic rays, which are accelerated in their powerful jets. The origin of these supermassive black holes is a long-standing unsolved problem, which may be solved by the 105 solar mass primordial seeds created by inflation.

High-energy neutrinos
PeV neutrinos, the most energetic neutrinos ever detected, were recently discovered by the IceCube collaboration. Their origin is a mystery, especially because they appear to have a relatively narrow spectrum.
The Kavli IPMU researchers have pursued two exciting possibilities: that these neutrinos originate fromsupermassive black holes, and that they come from decays of very massive dark-matter particles. New
data, expected later this year, will help interpret this exciting discovery and its ramifications for astroparticle physics.

Biplob Bhattacherjee

Collider phenomenology is now one of
the most important research-programs inparticle physics because the CERN Large
Hadron Collider (LHC) experiment has
been running since autumn 2009. In fact,
the LHC experiment has been providing
many precious data on the studies of thestandard model (SM) and physics beyond
the SM, and those are being used to test
various models of particle physics. The
members of the Kavli IPMU collider phenomenology group have therefore great
opportunities in exploring these physics,
and pursue a broad range of research.

Heavy gravitino dark matter can emerge from cosmological inflation naturally in a model proposed by
Kawasaki, Kitajima, Nakayama, and Yanagida.

TeV gamma rays from supermassive black holes in remote galaxies cannot travel large distances because
they lose energy in interactions with starlight and infrared light re-emitted by dust. Yet, some very energetic
gamma rays have been observed from some very distant objects. This created a puzzle. Lorentz invarianceviolation, as well as the existence of axion-like particles mixed with the photon, have been considered as possible explanations. However, Kusenko and collaborators showed that the observed spectra, as well as theirrelatively mild dependence on the redshift, can be explained by the secondary gamma-rays, which did not
originate at the source, but were produced in the cosmic ray interactions along the line of sight. This interpretation paves the way for measuring magnetic fields deep in the voids between galaxies, where the primordial
seed fields may have existed from the time of Big Bang. Furthermore, one can measure correctly the extragalactic background light, which reveals the history of star formation in the universe.

all the rest of the species in the universe. A new solution to this problem, supported by the discovery of a 125
GeV Higgs boson, automatically leads to dark matter in the form of moduli particles. This form of dark matter is consistent with the observed properties of structure formation, and it is amenable to detection with thehelp of X-ray telescopes. The first observations of the Draco and Ursa Minor dwarf spheroidal galaxies havenot produced a detection, but more observations are planned in the near future.

The LHC experiment is currently suggesting the existence of the higgs boson at about 125 GeV, while
no new physics signals have been discovered yet. These results are (and will be) used to have a deep understanding of physics beyond the SM at the TeV energy-scale.
It is also worth emphasizing that the study of the collider phenomenology at the Kavli IPMU has several
advantages, because the study is directly and indirectly influenced by other research-programs. Connections between the study of collider phenomenology and those of model buildings of particle physics,
dark matter searches, and cosmology are particularly of importance. As already mentioned in this report of other research-programs, the Kavli IPMU has many active researchers working on these topics.
It is thus possible for the members of the group to efficiently perform their studies.
In addition to collider phenomenology at the LHC experiment, some of the members are also studying
those at other collider experiments which are planned in near future. They are especially interested in thestudies of physics beyond the SM at High Luminosity-LHC (HL-LHC) experiment and future linear collider experiments such as the International Linear Collider (ILC) and Compact Linear Collider (CLIC).

Recent remarkable progress in cosmology is driven by vast observational data. Statistical analysis ofthese observational data constitutes an essential part of studies to explore physics behind the history andstructure of the Universe. In particular, proper use of statistical quantities is a central issue of cosmology, because cosmological information is encoded in the fluctuations of the spatial distributions of astronomical objects. While the initial fluctuations are known to follow Gaussian statistics, fluctuations in
the present Universe are quite non-Gaussian as a consequence of the evolution of the fluctuations via thegravitational instability, characterization of which requires the higher order statistics beyond the twopoint correlation function. This is a highly mathematical problem and is also one of the main themes in
the research program of the Cosmology and Statistics Group at the Kavli IPMU.
Another important problem in the comparison between theoretical models and observations is efficientparameter inference and model selection based on statistics. For example, Markov chain Monte Carlo
methods and Bayesian statistics have been introduced to cosmological analysis relatively recently, whichsignificantly advanced analysis of cosmological data. New large-area surveys such as Subaru HSC/PFS
will increase a tendency for applying sophisticated statistical techniques to the observational data. At
the Kavli IPMU, cosmologists and mathematicians work together to tackle this problem and explore
possible applications of new statistical techniques to cosmological analysis.

A 23% of all there is in the Universe is what we call Dark Matter. Dark because unlike normal matter(4% of all there is) it does not interact with light. So we cannot see it with our telescopes, although we
can clearly see its imprint on the distribution and movement of the visible stars and galaxies throughgravitational forces among them. But while in this way we can even map its distribution throughout theaccessible history of our universe, we have no clear hints yet as to its true nature.
One possibility is that Dark Matter takes part in the weak interaction of particle physics. As this particular possibility is very attractive also from the point of view of particle theory, it has given rise to avariety of dedicated experiments around the world. WIMP has become the shorthand for this type of
Dark Matter: Weakly Interacting Massive Particle.
The Kavli IPMU is involved in this effort through the XMASS experiment at its Kamioka branch.
In the XMASS detector one metric ton of xenon is kept as a liquid at minus 100 degree Celsius. The
dense liquid provides both a large target mass at its center as well as shielding against radioactive backgrounds. Fast neutrons from the surrounding rock are moderated and remaining muons tagged in an
800 ton active water shield in which the detector is immersed.
The first data was taken in fall 2011. After several improvements and further tuning of the detector system, the detector would become the world’s most sensitive detector for the direct detection of dark matter particles in our galaxy.

Experimental physics and observational astronomy rely on cuttingedge technologies to build detectorsthat push the frontier of knowledge
with the data they deliver. Data is
the lifeblood of science, as the scientific method demands that every
insight be tested against the hard
evidence of experimental data. The
art of experimentation is to provide
both reliable and pertinent data totest the theories that the disciplined
use of knowledge and imagination
conjure from the massive body ofscientific data already accumulated.
Act ive detector development
provides the means to extend thereach of current and future experiments – and very possibly newtechnology that may well find its
way back into your living room or workshop. It is a vital ingredient in our quest to understand the Universe.
The detector developments that are taking place at the Kavli IPMU are as diverse as the problems encountered and the individuals working on them.
• Developing‌a reliable scheme to add water-soluble gadolinium into the ultra-pure water volume ofSuper-Kamiokande. If successful, it can drastically lower the energy threshold and background for thedetection of supernova relic neutrinos.
• Developing‌an innovative purification method of a large-volume liquid noble gas such as Argon and
Xenon. These gases are used for the time projection chambers in future measurements of dark matterand neutrinos.
• Developing‌a multi-object spectrograph that uses optical fiber for the Subaru telescope. It allows spectroscopic analysis of many galaxies simultaneously and, therefore, is a powerful tool for large-scale
galaxy survey.
• ‌Developing techniques for assembling and optimizing the silicon vertex detector that measures the
decay vertices of B mesons with high resolution. Success of the Belle II experiment heavily relies on
this R&D.
• Exploring‌ways to significantly improve the sensitivity for the dark matter search: developing highpurity germanium detector, developing techniques for coupling the photomultiplier tube with thescintillating crystals such as sodium iodide and cesium iodide at the liquid nitrogen temperature, anddeveloping a dark matter detector module based on ultra-pure NaI(Tl) crystals.

Heavy Flavor Physics

Success of the Belle experiment at K EK was
highlighted by an overwhelming confirmationof Kobayashi-Maskawa mechanism for CP violationin 2001, for which the two were awarded the 2008
Nobel Prize. It established that the CP violation arises
from the quark mixing in the Standard Model. However, somewhat under-stressed but equally important
accomplishments by this experiment was to overconstrain the Cabibbo-Kobayashi-Maskawa unitarymatrix through high precision measurements of avariety of B-meson decays, providing a detailed phenomenological description of the flavor sector in theStandard Model.

Research Program

5.6

Although the statistics is limited, some of these measurements seem to be deviated from the Standard
Model prediction. They suggest possible existence of a hidden mechanism at a high energy scale. It isalso pointed out by several other experimental and theoretical studies.

Flavor physics has provided several critical breakthroughs in the history of establishing the Standard
Model. In particular, the Flavor-Changing Neutral Current (FCNC) processes, which appear only inquantum loop corrections, proved powerful for observing effects of heavier particles. Study of B-meson
decays is a natural place to investigate a wide range of the FCNC processes because the b quark belongs
to the third generation and hence its decay is involved with all existing generations of quarks. Powerfulness of flavor physics to elucidate physics beyond the Standard Model should be fully exploited, and thissituation remains the same even after energy frontier machines discover new particles. In addition to the
B-meson decay studies, search for a lepton-flavor violating decay in τ-lepton decays is also important.
The lepton-flavor violating decay is highly suppressed within the Standard Model, but a new physics
may enhance the process to a detectable level. Specifically one needs to address:• Is there any new CP-violating phase?
• Is there any new right-handed current?
• Is there any effect from new Higgs fields?
• Is there any new flavor violation such as lepton-flavor violation?
• Is there any new flavor symmetry that explains the CKM hierarchy?
The Belle II experiment at the SuperKEKB accelerator offers an excellent opportunity for further exploration into flavor physics. The SuperKEKB is an asymmetric-energy e +e− collider, expected to becommissioned in 2014. It operates at the Υ(4S)-resonance energy with the luminosity 40 times higher
than the KEKB accelerator and produces 50 times more B and anti-B-meson pairs in a boosted centerof-mass frame. The boost allows to measure the decay time of each B meson. The original Belle detector is being upgraded into Belle II so that it can maximally exploit the high luminosity operation of theSuperKEKB.
At the moment, the Kavli IPMU team plays a central role for assembling the silicon vertex detector thatis used to measure the decay vertices of B mesons. Once the construction period is over, the group will
study a wide range of subjects in flavor physics and search for a hint of new physics beyond the Standard Model.

Credit: NASA/WMAP Science TeamThe Universe is expanding; the further away a galaxy is, the faster it is moving, which is known as the
Hubble’s law. This observational fact implies that, if we go back in time, the Universe was small, dense
and extremely hot. The evolution of the early universe is described by the Friedmann-Lemaitre-Robertson-Walker (FLRW) universe, a homogeneous and isotropic solution of the Einstein equations of thegeneral relativity, and the standard big bang theory is based on the FLRW universe. The Hubble’s law,
the big bang nucleosynthesis (BBN), the comic microwave background (CMB) radiation provide key
support for the standard big bang theory. Those three observations still remain important probes of theearly Universe.
Despite its great success the big bang theory is plagued with serious theoretical issues such as the horizon problem, the flatness problem, and the monopole problem. Those problems are beautifully solved
by introducing an inflationary expansion at the very early stage of the Universe. What is more important about inflation is that quantum fluctuations of a scalar field driving the inflation (called an inflaton)
generate tiny density perturbations, which can account for the seed of the structures such as galaxies
and clusters of the galaxies seen in the current Universe. The properties of the density perturbations
depend on the inflation models, which can be probed by studying tiny inhomogeneities in the CMB
temperature anisotropy.
The recent progress in observational techniques has enabled us to study the evolution of the early universe with unprecedented precision, and our understanding of the Universe has significantly increased.
Nevertheless it is not fully known how the inflation occurred, how the universe was reheated after inflation, how the dark matter as well as the baryon asymmetry was created, whether there is large nonGaussianity in the density perturbations or not, and so on. The Inflation and Early Universe Groupwould like to tackle those questions in order to reveal how the universe evolved from the inflationary
epoch into what it looks like at present.

One can say that the history of mathematics is more or less equivalent to the history of mankind attacking
problems in reason or knowledge. Mathematics abstracts the truth behind generalities. It began as a useful toolin everyday physics in the sense that we count numbers, we measure length and volume. Then as seen in Euclidean geometry of Euclid or in the problem of determining the existence or non-existence of roots in algebraic
equations, the practical side became lost and mathematics becomes pure pursuit of knowledge of human kind.
Diophantine equations, Fermat’s lifework, do not affect our life at all whether they had integral solutions or not.
In the 17th century, Newton found differential and integral calculus, giving a language and method to describe
the law of dynamics in nature, so then mathematics encountered physics. This is a good example of mathematics providing the scientific community, and sometimes society in general, with a common language andmethod to describe phenomena in their study. This in turn helps to establish mathematician’s original concepts. Particularly in recent years the interaction between mathematics and physics has been in full flow.
This interaction is more important than ever, and mathematics of the 20th century developed through an enormous influence from physics. Gauge theory, quantum field theory, general relativity, and superstring theory
Kavli IPMU Annual Report 201225

Research Program

Although the influence is great, mathematicians have been and will be working on those problems in mathematics which arose, and are to be solved purely within mathematics. A prominent recent example is the resolution of Fermat’s last theorem. Notably, there exist examples where those tools developed purely mathematically have interesting applications in physics.
The Kavli IPMU is a very exceptional research environment for mathematicians, in that there always are
physicists nearby. The mathematicians at the Kavli IPMU are to develop both physics and mathematics
through much discussion with the physicists. However, the emphasis is on that the true interest of mathematics is in mathematics, so the researchers undertake their research with their top priority in the field ofmathematics.
Geometry:
Geometry is a collection of branches of mathematics, which studies mathematically defined geometric objects. For instance, geometric objects include topological spaces, differentiable manifolds, Riemannian manifolds, symplectic manifolds, complex manifolds, and algebraic varieties. These are not only geometric figures
but also have important mathematical structures, which make the theories behind them very rich. Also thegeometry plays an important role in describing our universe, and has contributed much to physics. For instance, Riemannian geometry is necessary in developing Einstein’s theory of general relativity. On the other
hand, by the influence of string theory, it has been found recently that there are deep connections among thesegeometric theories. The most significant example is the mirror symmetry, which predicts a duality between
symplectic manifolds and algebraic varieties. These have been developed as different mathematical fields, but
are now expected to be equivalent by the duality between the two different types of string theories. The mirror
symmetry is one of the themes of the study of geometry at the Kavli IPMU.
In the theory of mirror symmetry, a Calabi-Yau 3-fold plays an important role. It is an algebraic manifoldof complex dimension three (real dimension six), with a Ricci flat metric. In string theory, our universe isconsidered to be 10 dimensional, and a Calabi-Yau 3-fold appears as an extra six dimensional space. The mirror symmetry predicts an equivalence between period integrals on a Calabi-Yau 3-fold and a curve counting
theory (Gromov-Witten theory) on its mirror manifold. At the Kavli IPMU, there are specialists in each side,and the mirror symmetry is studied vigorously. K. Saito has studied the theory of periods for a long time, andfound the notion of Frobenius structures on the deformation spaces of the singularities. This Frobenius structure is now an essential tool in describing the mirror symmetry. T. Milanov is an expert in Gromov-Witten
theory, and studies the Frobenius structures determined by Gromov-Witten invariants.
Another way to describe the mirror symmetry is to use the homological algebra. This was proposed by Kontsevich in 1994, and it is formulated as an equivalence between the derived category of coherent sheaves on a
Calabi-Yau 3-fold and the derived Fukaya category on its mirror manifold. A. Bondal is a leading expert inderived categories of coherent sheaves, and invented the notions of exceptional collections, enhancement of
the derived category. These notions are now essential in the study of derived categories. Y. Toda studies stability conditions on derived categories, and Donaldson-Thomas type invariants counting stable objects in the derived categories. This corresponds to “BPS state counting” in string theory, and an interesting research subject
also in string theory.

In the 19th century, Évariste Galois discovered a symmetry hidden in such equations, which led to the invention of the notion of a group. After this discovery, the focus of the field of algebra shifted to understanding
deep hidden structures.
Homological algebra is one such example. Homological algebra stems from geometry and was originally a way
to count the number of holes of, say, doughnuts. Once geometric notions are abstracted to homological algebra, many new invariants which do not necessarily have an obvious geometric interpretation appear naturally.
Derived categories are one such example. Derived categories were originally invented as a tool for efficiently
computing (co)homologies, but today they are considered interesting in their own right. Mathematicians at the
Kavli IPMU are pursuing a number of interests in the field of derived categories. For example, one question ofinterest is how much information on a given variety the derived category of coherent sheaves over that variety
possesses. This question is currently – with the relation to mirror symmetry in mind – being actively studied by
A. Bondal and Y. Toda, as was written in Geometry section above. The Mathematics Group are also trying toconstruct additional frameworks, such as differential graded algebra for example, to encode more information
on a variety by enhancing the structures on its derived category or its abstraction, the triangulated category.
Another field of interest is groups or group actions. Groups were originally a language for describing symmetries behind solutions of equations, but nowadays, they are an indispensable tool not only in mathematics but
also in many areas of physics such as crystallography or gauge theory. Often, groups are studied through theirrepresentation theory. K. Saito considers sets of vanishing cycles coming from geometry as a generalization ofroot systems, and applies the corresponding theory of infinite dimensional Lie algebras and its representations
to geometry. In T. Kobayashi’s new theory of global analysis for minimal representation and visible action oncomplex varieties, which are his recent themes, groups appear as “leit motiv”, and the theory is expanded ina way special cases are connected to infinite dimensional representation theory. A. Tsuchiya studies the algebraic structures of logarithmic conformal field theory such as the representation theory of the chiral algebra
and conformal blocks. T. Kohno studies monodromy representations of braid groups appearing in conformal
field theory from the point of view of hypergeometric integrals.

Research Programin physics have provided major impetus in the field of mathematics such as algebraic geometry, differential
geometry, topology, representation theory, algebraic analysis, and number theory.

Some researchers at the Kavli IPMU also study equations, one of the original goals of algebra. One of theultimate goals of modern arithmetic is a framework called the Langlands program, which predicts that two
seemingly completely different looking sets of representations coming from arithmetic coincide in a naturalsense. This vast conjecture includes even Fermat’s last theorem as a very small part. It is therefore not surprising that this program is thought to be very difficult to realize, however a number of simpler variants exist. S.
Kondo and T. Abe are working on the local Langlands program and the Langlands program for function fields
for example. Yet another variant of the Langlands program, for which a connection to S-duality in physics has
been observed, is the geometric Langlands program. The Langlands program and its variants have therefore
become very active and important modern topics of research.
As one can see, the Mathematics Group study many branches of algebra here at the Kavli IPMU. Algebra may
not necessarily directly deal with understanding the universe and moreover most of the algebraists at the Kavli
IPMU are interested in mathematics in and of itself, not in its application to other fields. However, when theefforts of practitioners of different disciplines align, the benefit to all fields involved is huge. The daily effortsof the Mathematics Group in understanding the structures ubiquitous to mathematics feed directly into efforts
directed at understanding the most fundamental phenomena of nature. The Mathematics Group therefore
await the next great breakthrough rivaling Galois’ discovery of groups.

The study of the geometry at the Kavli IPMU does not restrict to the mirror symmetry, and the geometry is
studied from various viewpoint. T. Kobayashi studies the action of discrete groups on non-Riemannian homogeneous spaces, and develops an original theory from a new geometric viewpoints. He discovered that local
rigidity may fail even in higher dimensions for indefinite-Riemannian symmetric spaces, and is challenging todevelop spectral theory in connection with their deformation theory. Also T. Kohno studies quantum invariants on low dimensional manifolds, which are related to integrable systems and the conformal field theory. He
revealed a quantum group symmetry for homological representations of braid groups and described the imageof quantum representations of mapping class groups. In this way, there are various studies of the geometry at
the Kavli IPMU, and the Mathematics Group aim to have a further breakthrough by combining these studies.
Algebra:Algebra was originally the field of mathematics that studied numbers and equations. In fact, in the Middle
Ages, a central problem in algebra was solving algebraic equations of higher degrees.

Recent reports of excess in high-energy cosmic ray fluxes, deviation from the Standard Model
prediction of the anomalous magnetic moment of muon, and some other reports of deviations
from the Standard Model predictions may also be indications of some physics beyond the Standard Model. The Models beyond the Standard Model Group therefore seek for theoretical models
that account for these phenomena.

Standard Model

This Group also address the following problems. The Standard Model is described by a quantum field
theory with about 30 parameters, and the values of these parameters can be determined only by measuring them experimentally. Would it be possible to determine them theoretically, by considering theoretical frameworks that contain the Standard Model?
The thermal history of early universe is described very well by the Standard Model at least back to theera with the temperature of order MeV, but it is only with several input parameter values of the initialcondition of the universe. Those initial condition parameters include baryon asymmetry, normalizationof density contrast, and the amount of dark energy. How are these initial condition parameters set? Onceagain, it is impossible to think about such problems without a model that extends the Standard Model.

Electroweak Symmetry Breaking
Deviation from the SM
Experimental Deviations

The origin of the masses of the weak bosons is not the only puzzle of the Standard Model. It is known
that huge fraction of the universe consists of dark matter and dark energy. It is very unlikely that dark
matter is actually the ordinary matter particles in the Standard Model. This is where we find anothermotivation to extend the Standard Model. Our universe may have become so large because of an inflationary process in the early universe, and quantum fluctuations of a scalar field may become the fluctuations of density in the early universe, which eventually become galaxies and clusters of galaxies. So,
here is another motivation to introduce a new degree of freedom and extend the Standard Model. Suchcosmological issues as inflation, primordial density perturbations, and dark matter motivate extensionsof the Standard Model, and models in quantum field theories are the appropriate framework in order towork on these issues.

Research Program

5.10

In order to solve these questions theoretically, various models beyond the Standard Model have been
constructed so far, and we still continue to do so in quest of a better solution to these problems. Once wehave concrete models, we can examine whether such models are really consistent with all the available
experimental data, predict what kind of signals can be expected in future experiments, and even propose experiments to confirm such models.

Technicolor

Up to now, we have seen that a quantum field theory with quarks, leptons and vector bosons for threedifferent forces describes reasonably well all the experimental data available so far. Among the vectorbosons, however, those corresponding to the weak force (which is responsible for the β-decay of nucleons) are known to have masses. There are three such vector bosons, and they are called W +, W − andZ bosons, or weak bosons, as a whole. From the consistency of quantum field theories, it is known thatsomething must be behind the non-zero masses of these vector bosons.

For non-experts
After kB, c and ħ are set to unity, [length] = [energy] −1 is the only dimension left in physics. The
fundamental law of physics in nature has been probed down to the length scale of order 10−3 fm =10−8 Å, which is equivalent to the energy scale of order 102 GeV = 1011 eV. Nothing is known forsure yet, however, on what is happening at even shorter distance scales.

What is called the Standard Model provides a simple theoretical idea how the weak bosons acquiremasses. According to the Standard Model, the masses originate from condensation of quanta of a new
scalar boson, called Higgs boson. The Higgs boson was the last missing piece of the Standard Model,
and was discovered in LHC experiments in this year. The observed mass about 125 GeV is consistent
with the mechanism predicted by the Standard Model. This mass is also consistent with our prediction
in supersymmetric standard model with relatively large SUSY breaking at 10 ­– 100 TeV.
Is that the end of the story? Maybe ..., but maybe not. Let us think about the following questions.
• The‌Higgs boson is the only scalar field in the Standard Model; all other dynamical degrees of freedom in the Standard Model are either fermions or vector fields. Why does the Standard Model have
one scalar field, and just one? Why does its condensation develop?
•T‌ he Newton constant G N ≃ 6.7 × 10−11 m3kg/s2 corresponds to an energy scale 1/ G N ħ /c3 〜 1019
GeV. Why is there a huge hierarchy of order 1017 between this energy scale and theweak boson massesof order 102 GeV, and how can the weak boson masses remain so small under quantum corrections?

The Super-Kamiokande [Super-K] detector is a 50,000 ton tank of water buried deep under the JapaneseAlps. By studying neutrinos generated by cosmic ray interactions in the Earth’s atmosphere, in 1998
Super-K made the stunning discovery that different types of neutrinos can spontaneously transformfrom one type to another, a process known as neutrino oscillation. This also implied that at least two of
the three neutrinos have a small, but non-zero mass, something not predicted by the Standard Model.
This was the first time since its inception that the Standard Model needed to be revised based on solid
experimental data. In 2001 Super-K made a crucial contribution to the solution of the solar neutrino
problem by indicating that solar neutrinos produced by the Boron-8 reaction in the Sun could change
their flavor while in flight, and uniquely selected the large mixing angle solution to the problem. the Kavli IPMU members are now working on GADZOOKS!, an initiative to enrich the ultra-pure water inside Super-Kamiokande with the element gadolinium. This will greatly reduce backgrounds and, among
many other physics benefits, should allow the first-ever detection of a constant stream of neutrinos fromdistant supernovas.

What are the building blocks of nature? Most people have heard of electrons, which are indeed (as far
as we can tell) fundamental particles, as well as protons and neutrons, which are themselves composite
objects composed of much smaller fundamental particles called quarks. But there are much more unusual fundamental particles, too, and perhaps the most mysterious of these are the neutrinos.
The Standard Model of particle physics contains three generations of fundamental particles. In each ofthese generations, or families, there are two quarks and two much less massive particles called leptons.
In the first family one such lepton is the electron, which carries an electric charge, and the other firstgeneration lepton is called the electron neutrino, which is electrically neutral. The second generation
contains two more types of quarks, a charged lepton called the muon, and the muon neutrino, while thethird family contains a final pair of quarks, a charged lepton called the tau, and a tau neutrino.
The three types of neutrinos, the electron neutrino, the muon neutrino, and the tau neutrino, are exceedingly challenging to study, because they hardly interact with matter at all. That means neutrino
detectors need to be very big, very sensitive, or both. At the Kavli IPMU there are teams of researchers
working on some of the best and most famous neutrino detectors in the world.

Kavli IPMU Annual Report 2012

The KamLAND neutrino detector is located in the same ancient zinc mine as Super-Kamiokande, butinstead of water it is filled with 1,000 tons of liquid scintillator. This makes it very sensitive, especiallyto low energy neutrinos from nuclear reactors and those generated by radioactive decays within the
Earth itself. In 2002 KamLAND was the first experiment to observe disappearance of reactor neutrinos,
which matched other experiments’ solar neutrino data in spectacular fashion. After lowering the energy
threshold at which their data could be analyzed, in 2005 KamLAND was the first experiment to detect
Geo-neutrinos, ushering in an entirely new way to study the Earth’s interior. Also in 2005, KamLAND
saw evidence of spectral distortions in the reactor neutrino signal; clear proof of neutrino oscillations.
Whether neutrino is a Majorana particle or not (i.e., if neutrino coincides with its anti-particle or not)is critical for understanding the mechanism that created a small excess of matter in the early universe,
leading to the matter-dominated present-day universe. If neutrino is the Majorana particle, the double
beta-decay, which ordinarily emits two neutrinos or two anti-neutrinos, can proceed without neutrino or
anti-neutrino emission. This process is called neutrinoless double beta-decay. The Kavli IPMU members
are focusing on KamLAND-Zen project aimed at detection of neutrinoless double beta-decay of Xenon-136 using KamLAND. The first batch of data accumulated in 2011-2012 produced the most precise
measurement of ordinary double beta-decay half-life and the most stringent limit on the neutrinolessdouble beta-decay (including the most stringent limit on the Majoron coupling to the neutrino).
As we continue to understand the mysterious neutrinos, as well as the varied processes which produce
them within the Earth, upon the Earth, above the Earth, within the Sun, and inside exploding stars, theKavli IPMU researchers are using these tiniest of particles to probe the most inaccessible places andfarthest reaches of the universe itself.

Understanding the nature and origin of large-scale
structure in the Universe is one of the most compelaccelerated expansion
ling issues in observational cosmology. The curof the Universe
rently most conventional scenario is given by thecold dark matter (CDM) dominated model, where
gravitational instability mainly driven by spatial
telescope
inhomogeneities of CDM distribution amplifies
the seed density perturbations to form the presentgalaxy
day hierarchical structures. Therefore revealing
distribution and amount of CDM is crucial to understanding the formation of large-scale structure.
In addition the presence of dark energy drives theaccelerating cosmic expansion, and therefore affects
the growth of structure formation. The dark matter
distribution and the nature of dark energy can be explored from massive galaxy surveys.
The Observational Cosmology Group have been actively working both on the measurements using currently available telescope facilities and on the planning of future instruments. The two powerful investigative tools are the gravitational lensing effect and the baryon acoustic oscillation.
Gravitational lensing effect:
The path of light ray emitted by a distant galaxy is bent by gravitational force of intervening large-scale
structure during the propagation, causing the image to be distorted – the so-called weak lensing shear.
Conversely, measuring the coherent shear signals between galaxy images allows us to reconstruct the
distribution of invisible dark matter. Moreover, since the weak lensing shear deals with the light propagation on cosmological distance scales, the lensing strengths depend on the cosmic expansion history
that is sensitive to the nature of dark energy. Thus weak lensing based observables offer a powerful way
for studying the nature of invisible components, dark matter and dark energy. The Observational Cosmology Group are carrying out observational and theoretical studies of weak lensing phenomena using
their own Subaru data sets as well as simulations of large-scale structure.
Baryon acoustic oscillation:
To measure properties of dark energy, one needs to measure the expansion history of the Universe precisely. Because light travels at a finite speed, one can measure the expansion rate of the past by looking
far. Comparing the expansion rate at varying distances would reveal the expansion history. The expansion itself is relatively easy to measure. The light emitted by a distant galaxy is stretched by the expansion of space and becomes redder, which can be measured by any decent spectrograph.
32

Kavli IPMU Annual Report 2012

To measure the expansion history, however, one also needs to know how far back in time the light wasemitted from the galaxy, or equivalently, how far away it is. Measuring precise distances in cosmological scales is very challenging. Clustering of baryonic matter at a certain characteristic scale that is
imprinted by baryon acoustic oscillation (BAO), or propagation of acoustic waves, in the early universe
serves as a “standard ruler” for cosmological observations. This technique requires to study millions ofgalaxies in a wide field of view, and map the spatial distribution of luminous galaxies to detect the characteristic scale.
Hyper-Suprime Cam (HSC):The HSC is the project to replace the prime focus camera of Subaru Telescope (8.2 meter opticalinfrared telescope at the summit of 4,200 m high Mauna Kea, Hawaii) with a new camera that has wider
field-of-view than the previous one by a factor of 10. Fully utilizing the unique capabilities of HSC, its
survey speed and excellent image quality, a massive galaxy survey will be conducted covering an area ofa few thousands square degrees and reaching to the depth to probe the Universe up to redshifts of a few.
In fact these data sets will provide an ideal data sets for exploring the nature of dark matter and darkenergy via measurements of cosmological observables available from the data, weak lensing and galaxy
clustering statistics. The Kavli IPMU members are actively involved in this HSC project, and working
on the designing and planning of HSC galaxy survey and development of data analysis pipeline.

Sloan Digital Sky Survey III:In January 2011, the SDSS-III collaboration released the largest digital color image of the sky ever made.
The image has been put together over the last decade from millions of 2.8-megapixel images taken at the
2.5-meter telescope at the Apache Point Observatory in New Mexico, thus creating a color image of morethan a trillion pixels. This new SDSS-III data release, along with the previous SDSS-I and SDSS-II data
releases that it builds upon, gives astronomers the most comprehensive view of the night sky ever made.
SDSS data have already been used to discover nearly half a billion astronomical objects, including asteroids, stars, galaxies and distant quasars.
The Kavli IPMU has been a part of the SDSS-III and involved in the study of these rich images. But thefocus of the Observational Cosmology Group has been to conduct a new survey to a deeper universe with
the improved spectrograph. This survey, the Baryon Oscillation Spectroscopic Survey (BOSS), maps thespatial distribution of luminous galaxies and quasars to detect the characteristic scale imprinted by baryon
acoustic oscillations in the early universe. Using the acoustic scale as a standard ruler, the angular diameter distance to the galaxy redshift can be inferred. The BOSS has started to take data in 2009 and willcontinue until 2014. Its goal is to precisely measure how Dark Energy has changed over the recent historyof the Universe.
Prime Focus Spectrograph (PFS):The PFS project that mounts a next generation spectrograph on the Subaru telescope and is planned tostart data taking later this decade was overwelmingly endorsed at the Subaru Users meeting of January
2011. Using a wide angle view of Subaru telescope and the PFS, several thousand galaxies can be studied at the same time and the baryon acoustic oscillation technique can be used.
In addition to BAO, there are a number of other measurements to constrain the properties of dark energy using this instrument. Furthermore, this type of spectrograph with a large field of view and a massive multi-object capability will be unique among the largest telescopes in the world, allowing for unprecedented studies of formation and evolution of galaxies, as well as the assembly history of our own
Milky Way Galaxy.
The strength of this project comes from exploiting the data using the HSC. The combination of imaging
using HSC and spectroscopy using PFS is dubbed SuMIRe, Subaru Measurement of Images and Redshifts. The SuMIRe project is expected to repeat and exceed the tremendous success of Sloan Digital
Sky Survey (SDSS), but with a much deeper view of the Universe back to the era that formed early stars
and supermassive blackholes.

The stability of the proton represents one of the greatest
theoretical and experimental challenges in particle physics today. In most grand unified theories, particularly thosewith a TeV intermediate mass scale, the proton “wants” todecay. Experimentally, however, the proton seems determined to outlive us all. Beginning with the first large-scale
searches in the 1980’s, one promising theory after anotherhas floundered on the shoals of nucleon decay. To date, nohint of a nucleon decay signal has emerged.
In spite of this, the study of nucleon decay provides one of
the few approaches to the problem of confronting grandunified theories with experimental data, and any progress
toward this goal has unique value for the future development of physics. This program has already been a success.
The simplest unification model, minimal SU(5), has been
ruled out by the experimental results. Every subsequent
grand unification theory will remain only a mathematicalconstruct if further experimental information is not available.

The search for nucleon decay requires massive detectors. A search with a sensitivity of 1033 years, forexample, requires a detector with approximately 1033 nucleons. Since there are 6 × 1029 nucleons per tonof material, this implies detectors of multi-kiloton scale.
The “classical” proton decay mode, p → e+π0, can be efficiently detected with low background. At present, the best limit on this mode ( τ/β > 1.21 × 1034 yr, 90% CL, is the decay mode branching ratio)comes from a 206 kton·yr exposure of Super-Kamiokande. The detection efficiency of 45% is dominated by final-state π0 absorption or charge-exchange in the nucleus, and the expected background is 2
events/Mton·yr.
Supersymmetric theories favor the mode p → νK+, which is experimentally more difficult due to theunobservable neutrino. The present limit from Super-Kamiokande is the result of combining several
channels, the most sensitive of which is K+ → μ +ν accompanied by a de-excitation signature from theremnant 15N nucleus. Monte Carlo studies suggest that this mode should remain background free for theforeseeable future. The present combined limit is τ/β > 3.3 × 1033 yr (90% CL).
Recent theoretical work suggests that if super-symmetric SO(10) provides the framework for grandunification, the proton lifetime (into the favored νK + decay mode) must lie within about one order ofmagnitude of present limits. Similarly, SO(10) theories suggestτ/β(e + π0 ) ≈ 1035 years – about a factorof ten beyond the present limit. Thus, continued progress in the search for nucleon decay inevitably requires larger detectors.

In the past few hundred years, scientists havesearched for fundamental laws of nature by exploring phenomena at shorter and shorter distances. Does this progression continue indefinitely? Surprisingly, there are reasons to thinkthat the hierarchical structure of nature willterminate at 10 −35 meter, the so-called Planck
length. Let us perform a thought-experiment to
explain why this might be the case. Physicists
build particle colliders to probe short distances.
The more energy we use to collide particles,
the shorter distances we can explore. This has
been the case so far. One may then ask: can webuild a collider with energy so high that it canprobe distances shorter than the Planck length?
The answer is no. When we collide particles
with such high energy, a black hole will form and its event horizon will conceal the entire interaction
area. Stated in another way, the measurement at this energy would perturb the geometry so much thatthe fabric of space and time would be torn apart. This would prevent physicists from ever seeing what
is happening at distances shorter than the Planck length. This is a new kind of uncertainty principle.
The Planck length is truly fundamental since it is the distance where the hierarchical structure of nature will terminate.

Space and time do not exist beyond the Planck scale, and they should emerge from a more fundamental
structure. Superstring theory is a leading candidate for a mathematical framework to describe physics at
the Planck scale since it contains all the ingredients necessary to unify general relativity and quantum
mechanics and to deduce the Standard Model of particle physics. Superstring theory has helped us solve
various mysteries of quantum gravity such as the information paradox of black holes posed by Stephen
Hawking. The theory has given us insights into early universe cosmology and models beyond the Standard Model of particle physics. It provides powerful tools to study many difficult problems in theoretical physics – often involving strongly interacting systems – such as QCD (theory of quark interactions),
quantum liquid and quantum phase transitions. It has also inspired many important developments inmathematics. All of these aspects of string theory are vigorously investigated at the Kavli IPMU.

Moreover, the enormous mass and exposure required to improve significantly on existing limits (andthe unknowable prospects for positive detection) underline the importance of any future experiment’s
ability to address other important physics questions while waiting for the proton to decay. Proton decay
experiments have made fundamental contributions to neutrino physics and particle astrophysics in thepast, and any future experiment must be prepared to do the same.

There are rich structures in the present-day universe, such as stars, galaxies, and large scale structure.
The Structure Formation Group study how these objects are formed using large computer simulations
and sophisticated theoretical models.
The standard Big Bang model posits that the universe was nearly homogeneous and very hot when it
was born. Tiny “ripples” in the distribution of matter were generated through a rapid expansion phasecalled inflation in the very early universe. These primeval density fluctuations grew by the action ofgravity, eventually forming luminous objects such as galaxies.
The energy content of the universe and basic statistic that describe the condition of the early universe
have been determined with great accuracy from recent observations of cosmic microwave backgroundradiation, large-scale galaxy distribution and distant supernovae. Cosmology is now at a stage where
theory can make solid predictions, whereas a broad class of observations can be directly used to verify
them. The ongoing large-scale galaxy survey, the Sloan Digital Sky Survey III, and the planned Hyper
Suprime-Cam Survey will provide rich information on the nature of dark matter and dark energy. Accurate theoretical predictions are needed to make the full use of the observational data.
The primary interests of the Structure Formation Group are in primordial star formation in the early
universe, the formation and evolution of galaxies, and the formation of large-scale structure. Resultsfrom these studies are used for making plans for Subaru-HSC/PFS dark energy survey.

Supernovae are explosions of stars
at the end of their lives. Corecollapse supernovae (Type II, Ib,
and Ic) are the outcome of thegravitational collapse of massive
stars (i.e., more than eight times
as massive as the Sun), followed
by formation of a neutron star ora black hole, announced by a hugeamount of neutrinos and probably
gravitational wave. Thermonuclear
supernovae (Type Ia) are explosions driven by nuclear reactions
within a white-dwarf star.

in the Universe would be onlyhydrogen, helium and some minor elements, although in reality the Universe is filled with about a hundred different sorts of elements.
Their energy produced at the explosions is huge, and supernova explosions could play important roles
even in formation and evolution of galaxies. They are among the brightest objects in the Universe, highlighted by recently discovered super-luminous supernovae, and as such they can be used as a beacon toprobe the high redshift Universe. Finally, importance of understanding their natures is highlighted bytheir use as cosmological distance indicators, leading to the discovery of the Dark Energy.
Our understanding of the above issues is still far from satisfying, with various issues still under investigation. At the Kavli IPMU, a wide range of topics related to supernovae both in theory and observation/experiment are covered; Evolution of stars toward supernovae, theory of explosions, attempt todetect these neutrinos at Kamioka, nucleosynthesis of elements up to iron and beyond, formation of dust
grains, theory of optical emission from supernovae and evaluation of their use as cosmological distanceindicators, and observations using the Subaru telescope including future large survey planning with the
HSC. By unifying these attempts, The Supernova Group aim to comprehensively understand supernovae and their influences on the evolution of the Universe.

6.1 ‌Results from the First Phase of KamLAND-Zen

The KamLAND-Zen Collaboration has converted this combined half-life limit to a 90% C.L. upper limit of 〈 mββ〉 < (120 − 250) meV using NME calculations. The constraint from this result on thedetection claim is shown in the figure for different NME estimates. The combined result for 136Xe refutes the 0νββ detection claim in 76Ge at > 97.5% C.L. for all NMEs considered assuming that 0νββdecay proceeds via light Majorana neutrino exchange.

Double-beta (ββ) decay, in which two neutrons
are simultaneously transformed into two protons,
occurs rarely in even-even nuclei, for which
ordinary beta decay is energetically forbidden
or highly suppressed. It is a second-order weakinteraction process emitting two electron antineutrinos and two electrons and therefore denoted by 2νββ.

The KamLAND-Zen result is still limited by the unexpected background caused by 110mAg (β-decay, τ =360 days, Q = 3.01 MeV) which may originate from either Fukushima-I fallout or cosmogenic productions
by Xenon spallation. In order to remove 110mAg, KamLAND-Zen Collaboration is going to distill the liquid
scintillator and pursue other options such as IB replacement and further upgrades on the detector.

The experimental search for 2νββ had been pursued
over the past decades by small research groups withvery limited resources. This situation has changed
dramatically since the discovery of a non-zeroneutrino mass in a number of neutrino oscillation experiments, and today the search for ββdecay is conducted by several large-scale ββ experiments using different techniques. Experimental observation of 2νββ decay has now become
reality, and main efforts have been shifting
towards the search for hypothetical ββ decay
modes forbidden in the Standard Model.

Spontaneous Symmetry Breaking is a very universal concept applicable for a wide range of systems:
crystal, superfluid, neutron stars, Higgs boson, magnets, even why there are more right-handed people
with hearts on the left-hand side and many others. In particular, continuous symmetries produce gapless Nambu-Goldstone bosons that govern the phenomena at long wavelengths and small energies.
Yet there is a variety in the spectra of gapless excitations even when the symmetry breaking patterns
are the same. The original Nambu theory proposed in 1961 was constructed in the framework of aquantum field theory for elementary particles, assuming their interactions in vacuum at the absolute
zero temperature, and hence Lorentz-invariance. Therefore, this theory cannot be directly applied to
the Lorentz-non-invariant cases with finite temperature and density. Then truly basic questions, suchas the number of Nambu-Goldstone bosons or their dispersion relations, had been studied only on
case-by-case basis without a general framework. Kavli IPMU Director Hitoshi Murayama and his collaborator Haruki Watanabe recently proposed a framework to understand Nambu-Goldstone bosons
in a unified way by representing all known examples in a single-line Lagrangian of the low-energy
effective theory, thus extending the celebrated Nambu-Goldstone theorem to Lorentz-non-invariant
systems (Phys. Rev. Lett. 108, 251602 (2012), chosen for Editor’s Suggestion and Physics Sypnosis).
In Lorentz-invariant systems, the number of Nambu-Goldstone bosons n NGB is always equal to thenumber of broken symmetry generators nBG. All of them have the identical linear dispersion ω = c|k|.
However, once the Lorentz invariance is discarded, the situation varies from one system to another.
Murayama and Watanabe proved a general theorem that relates nNGB and nBG. It is shown that the number of Nambu-Goldstone bosons nNGB is less than the number of broken generators nBG when some ofthem form canonically conjugate pairs. The pairing occurs when the generators have a nonzero expectation value of their commutator. This result applies to all dynamical systems subject to spontaneous
symmetry breaking, under the assumption made, namely, there are no gapless excitations other thanNambu-Goldstone bosons. In particular, it is the first result showing the implications of spontaneous
symmetry breaking on the low energy spectrum in general, and is applicable to non-relativistic systems of interest in condensed-matter physics.
There is a clear geometrical picture behind this framework. The spontaneous symmetry breaking isalways characterized by a homogeneous space G/H. In Lorentz-invariant systems to the leading orderin energy and momenta, all that needs to be specified is G-invariant metric on G/H. Once Lorentz invariance is dropped, one also needs to specify a presymplectic structure on G/H, namely G-invariant

cal emission and radio observations of SN2011dh, some studies claimed that the actual progenitor musthave been a compact object. Therefore, the detected YSG star could have been a companion of the exploded star, or even an unrelated object that accidently matched the projected supernova location.
However the Kavli IPMU researchers presented evidence that the progenitor was an extended objectof radius compatible with that of a YSG star. This was done by modeling its early-time optical emission using hydrodynamical calculations. As shown in Figure 1, the early observed emission is only
reproduced based on the YSG star hypothesis. In March 2013, the HST imaging observational resultthat showed the disappearance of the YSG star was announced (Figure 2). The prediction by the Bersten group that the YSG would not be found was eventually confirmed by the observation.
The findings from hydrodynamical calculations
have led to two new questions that the Bersten etal. research group set out to answer: (1) how did thestar lose most of its hydrogen envelope? and (2) how
could a YSG star of those characteristics explode?

In this table, “Kaon” means a model describing kaon condensation. It
was discussed by T. Schäfer et al. [Phys. Lett. B 522, 67 (2001)]. To
deal with finite density, this model introduces the chemical potential μ,and Lorentz invariance is explicitly violated. “BEC” means F=1 spinor
Bose-Einstein condensate. There are ferromagnetic BEC and planar
BEC. The “Wigner Crystal” listed here corresponds the case in which
there is a magnetic field along the z direction.

6.3 A‌ Yellow Supergiant Star Was Found to Be
a Progenitor of a Type Ⅱb Supernova
A group of researchers including Melina Bersten, Ken’ichi Nomoto, Gaston Folatelli and Keiichi
Maeda of Kavli IPMU) presented evidence that a yellow supergiant (YSG) star found at the locationof supernova SN 2011dh in the famous nearby galaxy M51 was indeed the star that exploded. The
study of YSG progenitors had been controversial because they could not easily fit the theory of stellar
evolution. However, a confirmation on this topic came in March 2013 with an announcement of thedisappearance of a YSG star in images collected by the Hubble Space Telescope (HST) while the SN
faded enough. Bersten and collaborators have already predicted that the explosion should leave behinda very blue star that was the binary companion of exploded YSG. Their efforts now aim at confirming
the proposed model by detecting the blue companion in future HST observations.

Figure 1: Theoretical light curve for a yellow supergiant (yellow) and blue compact (blue) progenitor compared with the observations of SN 2011dh (cyanpoints). From the figure it is clear that the progenitor of SN 2011dh should be ayellow supergiant in order to reproduce the observation.

The nature and diversity of progenitor stars or progenitor systems of core-collapse supernovae are important open questions in the field of astrophysics. It is believed that most massive stars explode when
they become red supergiants, or, alternatively, blue compact stars (so-called Wolf-Rayet stars). Recent
detections of YSG stars as possible progenitors of supernovae have posed serious questions on our understanding of the evolution of massive stars.
Due to its proximity, SN 2011dh in M51 was one of the brightest and best studied supernovae of 2011
(See figure on page 37). It was classified as a type IIb supernova, that is, it showed hydrogen lines in
its initial spectrum which later evolved into a helium-dominated spectrum. This is indicative of a progenitor star that has lost most of its hydrogen-rich envelope prior to the explosion.
By searching through archival images taken by the Hubble Space Telescope before the supernova explosion, two groups of astronomers independently detected a source at a location closely matching thatof the supernova. Photometry of this pre-supernova source was compatible with a YSG star. The question then arose as to how such a star could undergo a supernova explosion. Stellar evolutionary models
predict that stars, which become massive enough to produce a supernova explosion by core collapse,
should end their lives as red supergiants – for the lower mass range – or as a blue compact star – forthe larger masses. The YSG phase is an intermediate, short-lived stage in the evolutionary models of
single stars; no supernova explosion is expected to occur at this stage. Moreover, based on early opti-

Figure 2: HST images obtained several years before (left) and almost two
years after (right) the explosion of SN 2011dh. From the comparison between
these two images it is evident that the yellow supergiant star present in the preexplosion image has disappeared, and we now see a dimmer remnant of thesupernova. This was reported in the Astronomical Telegram #4850 by Schuyler
D. Van Dyk (IPAC/Caltech), Alexei V. Filippenko, Ori Fox, Patrick Kelly (UCBerkeley), and Nathan Smith (University of Arizona)[http://www.astronomerstelegram.org/?read=4850].

Related with the question (1), there are two main
mechanisms proposed for stars to lose their outerlayers: the strong winds and the mass transfer ininteracting binary systems. For the former mechanism, it is believed that a star should have a mass at
the time of birth, which is larger than approximately
25 times the mass of the Sun to generate winds
strong enough to blow off its outer layers. Hydrodynamical models, however, set a strong constraint on
the mass of a progenitor star. The findings showedthat its core could have not been more massive than
8 times the mass of the Sun, which implies that theinitial mass of the entire star should be less than 25
times the mass of the Sun. Thus, with the possibilityof the winds ruled out, they tested the latter mechanism in which a progenitor transfers its mass to aclose companion, thereby losing most of its outerenvelope. The binary scenario has the advantage ofintroducing a reasonable mechanism for lower mass
stars to expel their envelopes.

closed two-form, which corresponds to the expectation
value of the commutators among the generators. In all
physically relevant cases, G/H has a projection π down
to a symplectic homogeneous space B, whose symplectic
structure ω is pulled back to G/H as π*ω. The 2nB generators on B form canonically conjugate pairs, giving rise
to nB Nambu-Goldstone bosons of Type-B. The remaining
generators on the fiber are not paired, corresponding to nA
Nambu-Goldstone bosons of Type-A. The total number ofbroken generators are nBG = nA + 2nB, while the total numberof Nambu-Goldstone bosons is nNGB = nA + nB ≤ nBG. Generically Type-A NGBs have linear dispersionsω∝ |k|, while
Type-B quadratic dispersionsω∝ |k|2. The authors verified these universal results in a vast number of examples in
the literature. Future studies include extra “light” degrees of
freedom beyond the Nambu-Goldstone bosons, spacetime
symmetries, pseudo-Nambu-Goldstone bosons when somesymmetries are explicitly broken, and quantum numbers of
topological defects.

With the aim of solving both questions (1) and (2),the Bersten et al. research team carried out stellar
evolution calculations for a system of two massive
stars in a close orbit, in which phases of mass transfer occur. By assuming a system of stars with initial
masses of 16 and 10 times the mass of the Sun andan initial period of 125 days (Figure 3), they wereable to obtain a configuration for the mass-donor star
– the one that eventually explodes – which closely
matches the observations of the YSG object in presupernova images and has a core mass consistent
with their hydrodynamical modeling. Moreover, theamount of hydrogen left in the envelope of the exploding star was in the correct range to classify thesupernova as type IIb.
With the explosion of the YSG star confirmed, there
is one last piece of the puzzle that still needs to befound: the existence of its companion star predicted

6.4   ‌Prediction of a Novel Phase Transition Inspired by
Axion Search – An Interdisciplinary Collaboration
between Researchers at the Kavli IPMU and theInstitute of Solid State Physics (ISSP)
The axion is a hypothetical elementary particle beyond the Standard Model of Particle Physics, proposed to solve the problem of CP violation in strong interactions. The axion is also one of leading candidates for the dark matter of the universe.
Many attempts have been made to detect the axion, for example, by applying a strong magnetic field,by converting the axion to the photon in a crystal of germanium, or by injecting high intensity laser
beams in a strong magnetic field. However, none of the experiments has identified a positive signatureof the axion yet. Hirosi Ooguri, Principal Investigator of the Kavli IPMU, introduced a new strategy todetect the axion, which involves a strong electric field instead of magnetic field. However, the required
electric field turned out to be too strong to realize his idea with existing experimental technologies.
It was when Ooguri had a chance encounter with Professor Masaki Oshikawa of the Institute for Solid
State Physics, that led Ooguri’s idea applied to condensed matter physics.
Quantum field theory is a basic mathematical framework of elementary particle physics; this framework is also used to study critical phenomena in condensed matter systems. For example, the Isingmodel in two dimensions at criticality is described by a massless free fermion. Remarkably, there is acondensed matter system whose low energy description involves a coupled system of the axion and theelectromagnetic field of the axion electrodynamics.
A topological insulator is a new type of material that behaves as an insulator in its interior but whose
surface contains conducting states. Its existence was predicted by theorists in 2005 and actual materials realizing this mechanism were discovered recently. It turns out that magnetic fluctuation in a
topological insulator can be effectively described by a system involving the Maxwell field, which is
coupled to a particle behaving like the axion. This axion like particle is not the same as the axion inparticle physics, but it shares many characteristics with the elementary particle axion.
Ooguri and Oshikawa studied the axion electrodynamics in the presence of a background electricfield. They theoretically found that system possesses instability in a strong electric field, which leads
to a phase transition as shown in the figure. Beyond the transition, the electric field is screened above a42

certain field strength and excess energy converted to a magnetic field. This phenomenon had not been known before their paper published. Furthermore, they
pointed out the possibility of observation of this phenomenon experimentally inthe solid state, using topological and other insulators.
In contrast to the elementary particle axion, whose parameters should be determined by the nature, physical parameters of the axion field in the condensed
matter experiments can be selected by adjusting doping materials. Especially,
when the effective mass of the axion is reduced, the possibility to observe thephase transition will be raised. It is pointed out that such new phenomena willappear also in the usual (non-topological) insulator depending on the combination of magnetic and electric fields.
Their research result was published in Physical Review Letters (Phys. Rev. Lett.
108, 161803 (2012)) as the first publication by a joint research between Kavli
IPMU and ISSP. The paper was selected for Editors Suggestion “based on the potential interest in the results presented and, importantly, on the success of the paper
in communicating its message, in particular to readers from other fields”.
In the absence of an externally-applied magnetic field, no magnetic field (B) exists before
the axion phase transition takes place. As aconsequence of the axion phase transition, amagnetic field appears. The direction of themagnetic field is perpendicular to the surfaceof the material and can be either upwards or
downwards.

This new discovery is the result of the accumulation of research knowledge in bothof these fields and was made possible by the cooperation of the Kavli IPMU and
ISSP, both at the Kashiwa campus. Such on-campus interdisciplinary exchanges
are expected to stimulate many more great research achievements in the future.

by the binary model. According to the calculations, the companion should become amassive blue star at the moment of the supernova explosion. Due to its high surface
temperature, this star should emit radiation
mostly lying in the ultraviolet range, withnegligible contribution to the total flux of thesystem in the optical range. The companion
was faint enough so that it was not detected in
pre-supernova images of the space telescope.
However, in the near future, as the supernova
continues to fade, a relatively faint companion
star should be discovered. The group at Kavli
IPMU has thus proposed to perform deep
ultraviolet observations with the HST in 2014
to provide a definitive test for the validity of
their models.

6.5   ‌Extraordinary Magnification of a Type Ia Supernova
A research team at the Kavli IPMU has identified the first ever Type Ia supernova (SNIa) magnified
by a strong gravitational lens. The discovery provides the first glimpse of the science that will sooncome out of deep, wide-field surveys with the Subaru Hyper Suprime-Cam and the Large Synoptic
Survey Telescope (LSST).
The supernova, named PS1-10afx, was uncovered by the Panoramic Survey Telescope & Rapid Response System 1 (Pan-STARRS1). Soon after it appeared, a team of scientists led by researchers at theHarvard-Smithsonian Center for Astrophysics realized that this supernova was special. Because theexpansion of the Universe results in “redshift” that stretches short wavelength (blue) light to longer (red)wavelengths, the very red color of PS1-10afx suggested a very distant source. A spectrum taken a few
days after discovery shows the telltale signature of interstellar gas near the supernova, and this sets
the redshift firmly at z=1.3883, which corresponds to a distance of 9 billion light years – far further
than typical Pan-STARRS1 discoveries.
Based on this distance and its relatively bright appearance, the Harvard team concluded that PS110afx was intrinsically very luminous. The inferred luminosity, about 100 billion times greater thanour Sun, is comparable to members of a new, rare variety of superluminous supernovae (SLSNe), butthat is where the similarities end. SLSNe typically have blue colors, and their brightness changes relatively slowly with time. PS1-10afx on the other hand was rather red even after correcting for its redshift, and its brightness changed as fast as normal supernovae. There is no known physical model thatcan explain how a supernova could simultaneously be so luminous, so red, and so fast.
Soon after the Harvard team announced their findings, Robert Quimby, a postdoctoral researcher at
Kavli IPMU, independently analyzed the data. Quimby is an expert in SLSNe and has played a key

Research Highlights

SNIa’s have a very useful property that has enabled cosmologists to chart the expansion of our Universe
over the last several billion years: there is a tight relation between how slowly SNIa’s change in brightness with time and how intrinsically luminous they are. Higher luminosity SNIa’s have broader light
curves (a graph of their brightness curves over time), and fainter SNIa’s have shorter light-curve widths.
So how does the light curve of PS1-10afx compare to a SNIa? After correcting for time dilation (anotherconsequence of our expanding Universe), the light-curve width of PS1-10afx is perfectly consistent
with a SNIa of normal luminosity, but the observed brightness of PS1-10afx is far too high for such a
distant SNIa (see the first figure).
Tapping into the mathematical and astrophysical know-how at Kavli IPMU, Quimby’s team found an
explanation: the anomalously high brightness could indicate that PS1-10afx was gravitationally lensed
by an object between us and the supernova. While light travels through space in “straight” lines, massive objects warp space and thus cause rays of light to “bend” around them. Thus if there is a sufficiently massive object aligned between us and PS1-10afx, light rays that would have gone off to otherparts of the cosmos will be focused on us, making PS1-10afx appear brighter (see the second figure).
This does not change the colors or spectra of the lensed object, nor does it change how fast the supernova evolves. The supernova simply appears brighter than it would otherwise be, just as was observedfor PS1-10afx.
The Kavli IPMU team’s identification of the first strongly lensed SNIa is unprecedented but not entirely unexpected. Masamune Oguri, one of the co-authors of Quimby’s team, took the lead in writinga paper a few years ago predicting that Pan-STARRS1 was capable of discovering strongly lensed
SNIa’s. He has also shown that such objects may be exploited to place precise constraints on the cosmology of the Universe. Now that Quimby’s team has shown how to identify them, next generation
surveys with the Hyper Suprime-Cam on Subaru and the planned LSST can be tuned to discover evenmore strongly lensed SNIa’s. These discoveries can be used to study the nature of dark mater, test
theories of gravity, and help reveal what our universe is made of.

The light curve of PS1-10afx compared to anormal SNIa.
The blue dots show the observations of PS110afx through a red (i-band) filter, which corresponds to ultra-violet (UV) light in the rest
frame of the supernova. The red squares
show UV observations of the nearby SNIa,

axis to match the width of PS1-10afx in its rest
frame. The dashed lines show a fit to the SN
2011fe data and this same curve shifted by aconstant factor of 30. The good agreementwith the PS1-10afx data shows that PS1-10afx
has the light curve shape of a normal SNIa,
but it is 30 times brighter than expected.

6.6   ‌The Pure Gravity Mediation Model
After the discovery of a new boson at the Large Hadron Collider (LHC) experiment, which seems
strongly to be the higgs boson predicted by the standard model (SM), people has again started considering new physics beyond the SM carefully. One of the most striking results in this discovery is thatits mass is observed at about 125 GeV, which means that the new physics is presumably described bya weakly interacting theory. Among several weakly interacting theories, supersymmetry (SUSY) is
the most promising candidate for the new physics. When SUSY particles exist within a TeV range as
expected in the pre-LHC era, however, the higgs mass of 125 GeV is difficult to be achieved. This factmeans that rather large SUSY breaking effects to the higgs self-coupling are mandatory and requiresa typical mass scale of sparticles such as squarks and slepton to be around 100 TeV. Interestingly, thispossibility was pointed out by Okada, Yamaguchi, and Yanagida more than twenty years ago. Suchhigh-mass sparticles are very compatible with non-observation of SUSY signals at the LHC and of
FCNC processes at flavor-related experiments.

role in their discovery. He quickly confirmed a part, but not all of the Harvard team’s conclusions.
PS1-10afx was indeed rather distinct from all known SLSNe, but the data struck Quimby as oddly familiar. He compared the features seen in the spectra of PS1-10afx to normal supernova, and, surprisingly, found an excellent match. The spectra of PS1-10afx are almost identical to normal SNIa.

As a downside of the high-mass sparticles, we lose a good candidate for dark matter in the SUSY
standard model. That is, when dark matter is one of the sparticles with a mass at around the 100 TeV
scale, energy density of dark matter is too high and not consistent with the recent observation of
the dark matter relic density in our universe. This problem is, however, naturally resolved when we
consider the simplest setup of SUSY breaking. Suppose that the breaking is caused by a non-singlet
SUSY breaking field with the gravitino mass being O(100) TeV and its effect is simply mediated bysupergravity interactions. Then all scalar sparticles and higgsinos acquire their masses at tree level
and those are predicted to be O(100) TeV. On the other hand, gaugino masses come from the one-loop
anomaly mediated contribution, as already discussed by Giudice, Luty, Murayama, and Rattazzi fifteen years ago.
This model is very attractive from the viewpoint of cosmology. First, neutral gauginos can be a goodcandidate for dark matter because their masses are suppressed by one-loop factor compared to thegravitino mass. Second, we are free from the gravitino problem because the gravitino with the massof O(100) TeV decays well before the big-bang nucleosynthesis. Third, the so-called Polonyi problem
does not exist because there is no singlet field in the SUSY breaking sector. Finally, the model is consistent with the leptogenesis scenario proposed by Fukugita and Yanagida, which is now regarded as
the most successful mechanism to generate the baryon asymmetry of the universe with being consistent with tiny neutrino masses and their mixings. This model is now called the pure gravity mediation
model (PGM).
Basic framework and the fact that the PGM is compatible with the higgs mass of 125 GeV were first
discussed by Ibe and Yanagida. Soon after that, the entire framework of the PGM and its certain phenomenological aspects were discussed by Ibe, Matsumoto, and Yanagida. Both two studies have been

done at Kavli IPMU. One of the important predictions of the PGM is that all gauginos are at or lessthan O(1) TeV and are within the accessible range of current and future collider experiments, while allother sparticles are much beyond this range.
Another important prediction is that the neutral wino is the lightest supersymmetric particle, namely acandidate for dark matter, in the most of parameter region of the PGM. The neutral wino is highly degenerate with the charged wino in mass. The charged wino has therefore a long decay length of O(110) cm, which provides distinct signatures of the PGM at collider experiments. Due to a high experimental sensitivity to the mass degeneracy, a precise calculation of the mass difference between these
two was found to be important and was recently performed at the two-loop level by Ibe, Matsumoto,and Sato at Kavli IPMU.

For the collider (LHC) physics, the following three processes are expected at the LHC to test the
PGM. The first one is the inclusive process of gluino pair productions, where a gluino decays intoa neutral or charged wino by emitting two quarks. This process currently gives a lower limit on thegluino mass as mgluino > 1.2 TeV. When the LHC accumulates 300 fb −1 data at the 14 TeV run, theprocess will cover the gluino mass up to 2.3 TeV. The next one is again the process of gluino pair productions but now with a disappearing track signal of charged wino decays. Though this process is notstronger than the inclusive one at present, it will play an important role in near future. The last one isthe direct production of the charged wino through electroweak interactions, where the disappearing
track signal is again considered. It currently gives a lower limit on the wino mass as mwino > 110 GeV.
All these analyses have been performed by Bhattacherjee, Feldstein, Ibe, Matsumoto, and Yanagida at
Kavli IPMU. The first figure shows some details of the results obtained in these analyses.

Research Highlights

After the model-building of the PGM, some detailed studies on its phenomenology were also carriedout at Kavli IPMU, and the following results have been obtained.

Present LHC constraints on wino and gluino masses are shown,
where the shaded regions have already been excluded at 95%
confidence level. Future expected sensitivities for an inclusive
process and those using the disappearing track are also shown,
where the date corresponding to an integrated luminosity of 300
fb −1 at 14 TeV run is assumed.

Another interesting phenomenology of the PGM is found in dark matter detections, because themodel predicts a neutral wino dark matter which has an annihilation cross section highly boosted by
the Sommerfeld enhancement, as pointed out by Hisano, Matsumoto and Nojiri about ten years ago.
As a result, the PGM can be tested in indirect detection experiments of dark matter such as FermiLAT, PAMELA and AMS-02. The detection using cosmic-ray anti-protons was discussed in the study
mentioned above, and it turned out that the AMS-02 will cover the whole parameter region of the
PGM. The detection using gamma-rays from Milky Way satellites has also been studied recently by
Bhattacherjee, Ibe, Ichikawa, Matsumoto and Nishiyama very carefully, and it has been found that thewhole parameter region can be covered at the Fermi-LAT when kinematical data of ultra-faint dwarf
spheroidals are sufficiently increased. Currently, this detection gives the most severe limit on the winomass as mwino > 300 GeV. The second figure shows some details obtained in these studies. It is also
worth noting that Ibe, Kamada, and Matsumoto pointed out that the wino dark matter may have somefraction of warm component if its mass is less than 500 GeV; it may be detected in future 21cm observations.
The PGM is now known to be one of the most interesting candidates for new physics beyond the SM,
and in fact it is frequently cited all over the world. As already mentioned above, the model was built
based on several of the important past studies on SUSY made by those who are now at Kavli IPMU.
In addition, much of the recent progress on this model is currently being made at Kavli IPMU.
For further details, see M. Ibe, S. Matsumoto, and R. Saito, Phys. Lett. B 721, 252 (2013).

Awards
David Spergel (left) and Eiichiro Komatsu (right) wereamong the twenty six members of the WMAP (Wilkinson
Microwave Anisotropy Probe) team that won the Gruber
Foundation’s 2012 Cosmology Prize, jointly with Charles
L. Benett of Johns Hopkins University. The WMAP project brought precise and accurate understandings of theage, content, geometry and origin of the universe, andled to the firm foundation of the Standard CosmologicalModel. The citation recognized that the exquisite specificity of these results had helped transform cosmology itself
from “appealing scenario into precise science.”
Komatsu also won the 2012 Lancelot M. Berkeley – New York Community
Trust Prize for Meritorious Work in Astronomy. The prize is given annually tohighly meritorious work in advancing the science of astronomy during the previous year. He received the prize for his paper, “Seven-Year Wilkinson Microwave
Anisotropy Probe (WMAP) Observations: Cosmological Interpretation.” Komatsu has been a member of the WMAP team since 2001 and was the first authorof the papers presenting the cosmological interpretation of their five- and sevenyear data sets.
Hirosi Ooguri won the Inaugural Simons Investigator Award. Ooguri receives
more than 1.3 million US dollars over the next ten years for his research. The
goal of this new program is “to provide a stable base of support for outstanding
scientists in their most productive years, enabling them to undertake long-term
study of fundamental questions.” Nine theoretical physicists, seven mathematicians, and five computer scientists were appointed as Simons Investigators. Each
recipient will be granted funds to be applied to their individual research, theirdepartment, and their institution for an initial period of five years, beginning
August 2012. The foundation anticipates renewing the grants for an additional
five years in 2017. Ooguri was recognized in the citation as a “mathematicalphysicist and string theorist of exceptional creativity and breadth.” He was chosen as an investigator for his “innovations in the use of topological string theory
to compute Feynman diagrams in superstring models,” as well as for his cuttingedge work on the relationship of supersymmetric gauge theories to string theory
and to gravity.
Ooguri was also selected to join the inaugural group of Fellows of the American
Mathematical Society (AMS). The AMS Fellows program recognizes members
who have made outstanding contributions to the creation, exposition, advancement, communication, and utilization of mathematics. The responsibilities ofFellows are to take part in the election of new Fellows, to present a “public face”
of excellence in mathematics, and to advise the President and the Council on
public matters when requested.
The 2012 Geometry Prize of the Mathematical Society of Japan is awarded to
Yukinobu Toda for “The study of the Donaldson-Thomas invariants by stability
conditions in derived categories.” The Geometry Prize was established in 1987
by the donation by a group of researchers in geometry. This prize is awarded
to researchers who have contributed to the development of geometry in a broad
sense by obtaining outstanding results.

Kunio Inoue won the 2012 Nishina Memorial Prize. He has been playing a leading role in the KamLAND (Kamioka liquid scintillator anti-neutrino detector)
experiment, and, in particular, he has been making efforts to reduce various
backgrounds in the KamLAND detector by substantially improving it. These efforts have led to the first observation of terrestrial anti-neutrinos (geoneutrinos)
originating from radioactive decays of uranium and thorium inside the earth in2005. Subsequently in 2011, the KamLAND experiment measured substantiallyless radiogenic heat production in the earth with respect to the surface heat flow,
and consequently showed direct evidence for secular cooling of the earth. The
Foundation said, “His successful works explore interdisciplinary researches using neutrinos and are the foundations of development of neutrino geophysics bydirect observation of inside the earth.”
He was also awarded the 4th Yoji Totsuka Memorial Prize jointly with Atsuto
Suzuki, Director General of High Energy Accelerator Research Organization(KEK), for “Neutrino research with liquid scintillator, observation of geologically produced anti-neutrinos”. This prize has been awarded annualy since 2010by the Heisei Foundation for Basic Science.

Brice Ménard was selected by the Maryland Academy of Sciences as the 2012
Outstanding Young Scientist. He was recognized for his research in extragalactic astrophysics and cosmology. The award program was established in 1959
to recognize and celebrate the extraordinary contributions of young Maryland
researchers across all fields of science.
