IIB Duals of D=3 N=4 Circular Quivers

We construct the type-IIB $AdS_4\times K$ supergravity solutions which are
dual to the three-dimensional ${\cal N}=4$ superconformal field theories that
arise as infrared fixed points of circular-quiver gauge theories. These
superconformal field theories are labeled by a triple $(\rho,\hat \rho,L)$
subject to constraints, where $\rho$ and $\hat \rho$ are two partitions of a
number $N$, and $L$ is a positive integer. We show that in the limit of large
$L$ the localized five-branes in our solutions are effectively smeared, and
these type-IIB solutions are dual to the near-horizon geometry of M-theory
M2-branes at a $\mathbb{C}^4/(Z_k\times Z_{\hat k})$ orbifold singularity. Our
IIB solutions resolve the singularity into localized five-brane throats,
without breaking the conformal symmetry. The constraints satisfied by the
triple $(\rho,\hat\rho,L)$, together with the enhanced non-abelian flavour
symmetries of the superconformal field theories, are precisely reproduced by
the supergravity solutions. As a bonus, we uncover a novel type of "orbifold
equivalence" between different quantum field theories and provide quantitative
evidence for this equivalence.Comment: 53 pages, 16 figures. Added several comments and some extra

First Glimpses at Higgs' face

The 8 TeV LHC Higgs search data just released indicates the existence of a
scalar resonance with mass ~ 125 GeV. We examine the implications of the data
reported by ATLAS, CMS and the Tevatron collaborations on understanding the
properties of this scalar by performing joint fits on its couplings to other
Standard Model particles. We discuss and characterize to what degree this
resonance has the properties of the Standard Model (SM) Higgs, and consider
what implications can be extracted for New Physics in a (mostly)
model-independent fashion. We find that, if the Higgs couplings to fermions and
weak vector bosons are allowed to differ from their standard values, the SM is
~ 2 sigma from the best fit point to current data. Fitting to a possible
invisible decay branching ratio, we find BR_{inv} = 0.05\pm 0.32\ (95% C.L.) We
also discuss and develop some ways of using the data in order to bound or rule
out models which modify significantly the properties of this scalar resonance
and apply these techniques to the global current data set.Comment: 26 pages, 7 figures, v2 post ICHEP data updat
Topologically gauged superconformal Chern-Simons matter theories

By coupling {\cal N}=8 superconformal matter to {\cal N}=8 superconformal
Chern-Simons gravity in three dimensions we obtain theories with novel terms in
the scalar potential leading to AdS_3 solutions and superconformal symmetry
breaking. If we start from the theory derived by Bagger, Lambert and
Gustavsson, our coupled theory either inherits the SO(4) gauge group or reduces
it to SO(3). If the construction is instead based on a free matter theory we
find that the gravitational topological gauging also requires the introduction
of a Chern-Simons gauge sector resulting in a consistent theory for any SO(N)
gauge group.Comment: 46 pages, typos corrected, references added, discussion on background

Parent formulations, frame-like Lagrangians, and generalized auxiliary
  fields

We elaborate on the recently proposed Lagrangian parent formulation. In
particular, we identify a natural choice of the allowed field configurations
ensuring the equivalence of the parent and the starting point Lagrangians. We
also analyze the structure of the generalized auxiliary fields employed in the
parent formulation and establish the relationship between the parent Lagrangian
and the recently proposed Lagrange structure for the unfolded dynamics. As an
illustration of the parent formalism a systematic derivation of the frame-like
Lagrangian for totally symmetric fields starting from the Fronsdal one is
given. We also present a concise and manifestly sp(2)-symmetric form of the
off-shell constraints and gauge symmetries for AdS higher spin fields at the
nonlinear level.Comment: 36 pages, typos corrected, references added, extra comment on page 32

Irregular singularities in Liouville theory

Motivated by problems arising in the study of N=2 supersymmetric gauge
theories we introduce and study irregular singularities in two-dimensional
conformal field theory, here Liouville theory. Irregular singularities are
associated to representations of the Virasoro algebra in which a subset of the
annihilation part of the algebra act diagonally. In this paper we define
natural bases for the space of conformal blocks in the presence of irregular
singularities, describe how to calculate their series expansions, and how such
conformal blocks can be constructed by some delicate limiting procedure from
ordinary conformal blocks. This leads us to a proposal for the structure
functions appearing in the decomposition of physical correlation functions with
irregular singularities into conformal blocks. Taken together, we get a precise
prediction for the partition functions of some Argyres-Douglas type theories on
the four-sphere.Comment: 84 pages, 6 figure
Black holes in Truncated Higher Spin AdS$_3$ Gravity

We study the higher spin black holes in a truncated version of higher spin
gravity in $AdS_3$. This theory contains only finite number of even spins
s=2,4,...,2N. We mainly focus on the simplest case, so-called (Type I and II)
spin ${\tilde 4}$ gravity, which contains only spin 2 and spin 4 fields. This
spin ${\tilde 4}$ gravity is as simple as spin 3 gravity, thus provides another
example to test various ideas on higher spin gravity. We find that the
asymptotical symmetry of this spin ${\tilde 4}$ gravity is a classical
W(2,4)-symmetry. Moreover, we study the black hole solution with pure spin 4
hair and discuss its thermodynamics. One important feature of this black hole
is that its entropy could be written in compact forms. Furthermore, we
investigate a $G_2$ generated higher spin gravity. This higher spin gravity
only contains spin 2 and spin 6 fields which makes it different from other
kinds of higher spin gravity. We find the corresponding black hole with spin 6
hair, and discuss its thermodynamics analytically. It turns out that the black
holes with spin 4 or spin 6 hair constructed in this paper are the only black
holes with single higher spin hair, besides the spin 3 black hole found in
arXiv:1103.4304.Comment: 23 pages;minor revision, references added; published versio
Predictions from Heavy New Physics Interpretation of the Top
  Forward-Backward Asymmetry

We derive generic predictions at hadron colliders from the large
forward-backward asymmetry observed at the Tevatron, assuming the latter arises
from heavy new physics beyond the Standard Model. We use an effective field
theory approach to characterize the associated unknown dynamics. By fitting the
Tevatron t \bar t data we derive constraints on the form of the new physics.
Furthermore, we show that heavy new physics explaining the Tevatron data
generically enhances at high invariant masses both the top pair production
cross section and the charge asymmetry at the LHC. This enhancement can be
within the sensitivity of the 8 TeV run, such that the 2012 LHC data should be
able to exclude a large class of models of heavy new physics or provide hints
for its presence. The same new physics implies a contribution to the
forward-backward asymmetry in bottom pair production at low invariant masses of
order a permil at most.Comment: 11 pages, 6 figures. v2: added remarks on EFT validity range, dijet

NNLO corrections to top-pair production at hadron colliders: the
  all-fermionic scattering channels

This is a second paper in our ongoing calculation of the
next-to-next-to-leading order (NNLO) QCD correction to the total inclusive
top-pair production cross-section at hadron colliders. In this paper we
calculate the reaction $q\bar q \to t\bar t + q\bar q$ which was not considered
in our previous work on $q\bar q \to t\bar t +X$ due to its phenomenologically
negligible size. We also calculate all remaining fermion-pair-initiated
partonic channels $qq', q\bar q'$ and $qq$ that contribute to top-pair
production starting from NNLO. The contributions of these reactions to the
total cross-section for top-pair production at the Tevatron and LHC are small,
at the permil level. The most interesting feature of these reactions is their
characteristic logarithmic rise in the high energy limit. We compute the
constant term in the leading power behavior in this limit, and achieve
precision that is an order of magnitude better than the precision of a recent
theoretical prediction for this constant. All four partonic reactions computed
in this paper are included in our numerical program Top++. The calculation of
the NNLO corrections to the two remaining partonic reactions, $qg\to t\bar t+X$
and $gg\to t\bar t+X$, is ongoing.Comment: 1+16 pages; 3 figure
Gamma Lines without a Continuum: Thermal Models for the Fermi-LAT 130
  GeV Gamma Line

Recent claims of a line in the Fermi-LAT photon spectrum at 130 GeV are
suggestive of dark matter annihilation in the galactic center and other dark
matter-dominated regions. If the Fermi feature is indeed due to dark matter
annihilation, the best-fit line cross-section, together with the lack of any
corresponding excess in continuum photons, poses an interesting puzzle for
models of thermal dark matter: the line cross-section is too large to be
generated radiatively from open Standard Model annihilation modes, and too
small to provide efficient dark matter annihilation in the early universe. We
discuss two mechanisms to solve this puzzle and illustrate each with a simple
reference model in which the dominant dark matter annihilation channel is
photonic final states. The first mechanism we employ is resonant annihilation,
which enhances the annihilation cross-section during freezeout and allows for a
sufficiently large present-day annihilation cross section. Second, we consider
cascade annihilation, with a hierarchy between p-wave and s-wave processes.
Both mechanisms require mass near-degeneracies and predict states with masses
closely related to the dark matter mass; resonant freezeout in addition
requires new charged particles at the TeV scale.Comment: 17 pages, 8 figure
Distinguishing Various Models of the 125 GeV Boson in Vector Boson
  Fusion

The hint of a new particle around 125 GeV at the LHC through the decay modes
of diphoton and a number of others may point to quite a number of
possibilities. While at the LHC the dominant production mechanism for the Higgs
boson of the standard model and some other extensions is via the gluon fusion
process, the alternative vector boson fusion is more sensitive to electroweak
symmetry breaking through the gauge-Higgs couplings and therefore can be used
to probe for models beyond the standard model. In this work, using the well
known dijet-tagging technique to single out the vector boson fusion mechanism,
we investigate its capability to discriminate a number of models that have been
suggested to give an enhanced inclusive diphoton production rate, including the
standard model Higgs boson, fermiophobic Higgs boson, Randall-Sundrum radion,
inert-Higgs-doublet model, two-Higgs-doublet model, and the MSSM. The rates in
vector-boson fusion can give more information of the underlying models to help
distinguishing among the models.Comment: 31 pages, 3 figures; in this version some wordings are change
It is a Graviton! or maybe not

The discovery of Kaluza-Klein (KK) gravitons is a smoking gun of extra
dimensions. Other scenarios, however, could give rise to spin-two resonances of
a new strongly-coupled sector and act as impostors. In this paper we prove that
a spin-two resonance does not couple to the Standard Model through
dimension-four operators. We then show that the massive graviton and its
impostor both couple to the Standard Model through the same dimension-five
operators. Therefore the spin determination is identical. Nevertheless, we also
show that one can use the ratio of branching ratios to photons and to jets for
distinguishing between KK gravitons and their impostors. The capacity to
distinguish between KK gravitons and impostors is a manifestation of the
breakdown of the duality between AdS and strongly-coupled theories.Comment: 14 pages, 3 figures, 1 table. References added, typos correcte
Yukawa-unified natural supersymmetry

Previous work on t-b-\tau Yukawa-unified supersymmetry, as expected from SUSY
GUT theories based on the gauge group SO(10), tended to have exceedingly large
electroweak fine-tuning (EWFT). Here, we examine supersymmetric models where we
simultaneously require low EWFT ("natural SUSY") and a high degree of Yukawa
coupling unification, along with a light Higgs scalar with m_h\sim125 GeV. As
Yukawa unification requires large tan\beta\sim50, while EWFT requires rather
light third generation squarks and low \mu\sim100-250 GeV, B-physics
constraints from BR(B\to X_s\gamma) and BR(B_s\to \mu+\mu-) can be severe. We
are able to find models with EWFT \Delta\lesssim 50-100 (better than 1-2% EWFT)
and with Yukawa unification as low as R_yuk\sim1.3 (30% unification) if
B-physics constraints are imposed. This may be improved to R_yuk\sim1.2 if
additional small flavor violating terms conspire to improve accord with
B-constraints. We present several Yukawa-unified natural SUSY (YUNS) benchmark
points. LHC searches will be able to access gluinos in the lower 1-2 TeV
portion of their predicted mass range although much of YUNS parameter space may
lie beyond LHC14 reach. If heavy Higgs bosons can be accessed at a high rate,
then the rare H, A\to \mu+\mu- decay might allow a determination of
tan\beta\sim50 as predicted by YUNS models. Finally, the predicted light
higgsinos should be accessible to a linear e+e- collider with \sqrt{s}\sim0.5
TeV.Comment: 18 pages, 7 figures, pdflatex; 3 references adde
E11, generalised space-time and equations of motion in four dimensions

We construct the non-linear realisation of the semi-direct product of E11 and
its first fundamental representation at low levels in four dimensions. We
include the fields for gravity, the scalars and the gauge fields as well as the
duals of these fields. The generalised space-time, upon which the fields
depend, consists of the usual coordinates of four dimensional space-time and
Lorentz scalar coordinates which belong to the 56-dimensional representation of
E7. We demand that the equations of motion are first order in derivatives of
the generalised space-time and then show that they are essentially uniquely
determined by the properties of the E11 Kac-Moody algebra and its first
fundamental representation. The two lowest equations correctly describe the
equations of motion of the scalars and the gauge fields once one takes the
fields to depend only on the usual four dimensional space-time
The static quark potential from a multilevel algorithm for the improved
  gauge action

We generalize the multilevel algorithm of Luescher and Weisz to study SU(N)
Yang-Mills theories with the tree-level improved gauge action. We test this
algorithm, comparing its results with those obtained using the Wilson action,
in SU(3) and SU(4) Yang-Mills theories in 2+1 and 3+1 dimensions. We measure
the static quark potential and extract the Luescher term, predicted by the
bosonic string theory.Comment: 26 pages, 10 figures. V2: Restructured subsection 2.2, added

Back-reaction of Non-supersymmetric Probes: Phase Transition and
  Stability

We consider back-reaction by non-supersymmetric D7/anti-D7 probe branes in
the Kuperstein-Sonnenschein model at finite temperature. Using the smearing
technique, we obtain an analytical solution for the back-reacted background to
leading order in N_f/N_c. This back-reaction explicitly breaks the conformal
invariance and introduces a dimension 6 operator in the dual field theory which
is an irrelevant deformation of the original conformal field theory. We further
probe this back-reacted background by introducing an additional set of probe
brane/anti-brane. This additional probe sector undergoes a chiral phase
transition at finite temperature, which is absent when the back-reaction
vanishes. We investigate the corresponding phase diagram and the thermodynamics
associated with this phase transition. We also argue that additional probes do
not suffer from any instability caused by the back-reaction, which suggests
that this system is stable beyond the probe limit.Comment: 56 pages, 8 figures. References updated, improved discussion on

On Nontrivial Solutions around a Marginal Solution in Cubic Superstring
  Field Theory

We construct tachyon vacuum and half-brane solutions, using an extension of
KBc algebra, in the theory around a type of identity-based marginal solutions
in modified cubic superstring field theory. With explicit computations, we find
that their vacuum energies are the same as those of corresponding solutions
around the original theory. It implies that the vacuum energy for the
identity-based marginal solution vanishes although straightforward computation
of it is subtle. We also evaluate the gauge invariant overlaps for those
nontrivial solutions. The values for them are deformed according to the
marginal solution in the same way as the case of bosonic string field theory.Comment: 23 pages; v2:minor correction
Time-dependent angular analysis of the decay B0 s → J / ψ φ and extraction of ΔΓ s and the CP-violating weak phase φ s by ATLAS

Journal of High Energy Physics 2012.12 (2012): 072 reproduced by permission of Scuola Internazionale Superiore di Studi Avanzati (SISSA)Artículo escrito por un elevado número de autores, solo se referencian el que aparece en primer lugar, el nombre del grupo de colaboración, si le hubiere, y los autores pertenecientes a la UAMA measurement of B0 s → J /ψφ decay parameters, including the CP -violating weak phase φ s and the decay width difference ΔΓ s is reported, using 4.9 fb-1 of integrated luminosity collected in 2011 by the ATLAS detector from LHC pp collisions at a centre-of-mass energy √s = 7 TeV. The mean decay width Γs and the transversity amplitudes |A 0(0)|2 and |AІІ(0)|2 are also measured. The values reported for these parameters are: φs = 0.22 ± 0.41 (stat) ± 0.10 (syst) rad} ΔΓ s = 0.053 ± 0.021 (stat) ± 0.010 (syst) ps-1 Γ s = 0.677 ± 0.007 (stat) ± 0.004 (syst) ps-1 |A0(0)|2 = 0.528 ± 0.006 (stat) ± 0.009 (syst) |AІІ(0)|2 = 0.220 ± 0.008 (stat) ± 0.007 (syst) where the values quoted for φ s and ΔΓ s correspond to the solution compatible with the external measurements to which the strong phase δ⊥ is constrained and where ΔΓ s is constrained to be positive. The fraction of S-wave KK or f 0 contamination through the decays B0 s→ J /ψK + K-  (f0) is measured as well and is found to be consistent with zero. Results for φ s and ΔΓ s are also presented as 68%, 90% and 95% likelihood contours, which show agreement with Standard Model expectation
Octet baryon masses in next-to-next-to-next-to-leading order covariant
  baryon chiral perturbation theory

We study the ground-state octet baryon masses and sigma terms using the
covariant baryon chiral perturbation theory (ChPT) with the
extended-on-mass-shell (EOMS) renormalization scheme up to
next-to-next-to-next-to-leading order (N$^3$LO). By adjusting the available 19
low-energy constants (LECs), a reasonable fit of the $n_f=2+1$ lattice quantum
chromodynamics (LQCD) results from the PACS-CS, LHPC, HSC, QCDSF-UKQCD and
NPLQCD collaborations is achieved. Finite-volume corrections to the lattice
data are calculated self-consistently. Our study shows that N$^3$LO BChPT
describes better the light quark mass evolution of the lattice data than the
NNLO BChPT does and the various lattice simulations seem to be consistent with
each other. We also predict the pion and strangeness sigma terms of the octet
baryons using the LECs determined in the fit of their masses. The predicted
pion- and strangeness-nucleon sigma terms are $\sigma_{\pi N}=43(1)(6)$ MeV and
$\sigma_{s N}=126(24)(54)$ MeV, respectively.Comment: 28 pages, 6 figures, minor revisions, typos corrected, version to

Majorana Zero-modes and Topological Phases of Multi-flavored
  Jackiw-Rebbi model

Motivated by the recent Kitaev's K-theory analysis of topological insulators
and superconductors, we adopt the same framework to study the topological phase
structure of Jackiw-Rebbi model in 3+1 dimensions. According to the K-theory
analysis based on the properties of the charge conjugation and time reversal
symmetries, we classify the topological phases of the model. In particular, we
find that there exist $\mathbf{Z}$ Majorana zero-modes hosted by the
hedgehogs/t'Hooft-Polyakov monopoles, if the model has a $T^2=1$ time reversal
symmetry. Guided by the K-theory results, we then explicitly show that a single
Majorana zero mode solution exists for the SU(2) doublet fermions in some
co-dimensional one planes of the mass parameter space. It turns out we can see
the existence of none or a single zero mode when the fermion doublet is only
two. We then take a step further to consider four-fermion case and find there
can be zero, one or two normalizable zero mode in some particular choices of
mass matrices. Our results also indicate that a single normalizable Majorana
zero mode can be compatible with the cancellation of SU(2) Witten anomaly.Comment: 29 pages, 3 figures; v2, typos correcte
Rotating black holes, global symmetry and first order formalism

In this paper we consider axisymmetric black holes in supergravity and
address the general issue of defining a first order description for them. The
natural setting where to formulate the problem is the De
Donder-Weyl-Hamilton-Jacobi theory associated with the effective
two-dimensional sigma-model action describing the axisymmetric solutions. We
write the general form of the two functions S_m defining the first-order
equations for the fields. It is invariant under the global symmetry group G_(3)
of the sigma-model. We also discuss the general properties of the solutions
with respect to these global symmetries, showing that they can be encoded in
two constant matrices belonging to the Lie algebra of G_(3), one being the
Noether matrix of the sigma model, while the other is non-zero only for
rotating solutions. These two matrices allow a G_(3)-invariant characterization
of the rotational properties of the solution and of the extremality condition.
We also comment on extremal, under-rotating solutions from this point of view.Comment: 26 pages, LaTeX sourc
Determining the chiral condensate from the distribution of the winding
  number beyond topological susceptibility

The first two non-trivial moments of the distribution of the topological
charge (or gluonic winding number), i.e., the topological susceptibility and
the fourth cumulant, can be computed in lattice QCD simulations and exploited
to constrain the pattern of chiral symmetry breaking. We compute these two
topological observables at next-to-leading order in three-flavour Chiral
Perturbation Theory, and we discuss the role played by the eta propagation in
these expressions. For hierarchies of light-quark masses close to the physical
situation, we show that the fourth cumulant has a much better sensitivity than
the topological susceptibility to the three-flavour quark condensate, and thus
constitutes a relevant tool to determine the pattern of chiral symmetry
breaking in the limit of three massless flavours. We provide the complete
formulae for the two topological observables in the isospin limit, and predict
their values in the particular setting of the recent analysis of the RBC/UKQCD
collaboration. We show that a combination of the topological susceptibility and
the fourth cumulant is able to pin down the three-flavour condensate in a
particularly clean way in the case of three degenerate quarks.Comment: 31 pages, 7 figures. Accepted for publication in EPJ
