Small Hairy Black Holes in Global AdS Spacetime

We study small charged black holes in global AdS spacetime in the presence of
a charged massless minimally coupled scalar field. In a certain parameter range
these black holes suffer from well known superradiant instabilities. We
demonstrate that the end point of the resultant tachyon condensation process is
a hairy black hole which we construct analytically in a perturbative expansion
in the black hole radius. At leading order our solution is a small undeformed
RNAdS black hole immersed into a charged scalar condensate that fills the AdS
`box'. These hairy black hole solutions appear in a two parameter family
labelled by their mass and charge. Their mass is bounded from below by a
function of their charge; at the lower bound a hairy black hole reduces to a
regular horizon free soliton which can also be thought of as a nonlinear Bose
condensate. We compute the microcanonical phase diagram of our system at small
mass, and demonstrate that it exhibits a second order `phase transition'
between the RNAdS black hole and the hairy black hole phases.Comment: 68+1 pages, 18 figures, JHEP format. v2 : small typos corrected and a

Covariant Description of Flavor Conversion in the LHC Era

A simple covariant formalism to describe flavor and CP violation in the
left-handed quark sector in a model independent way is provided. The
introduction of a covariant basis, which makes the standard model approximate
symmetry structure manifest, leads to a physical and transparent picture of
flavor conversion processes. Our method is particularly useful to derive robust
bounds on models with arbitrary mechanisms of alignment. Known constraints on
flavor violation in the K and D systems are reproduced in a straightforward
manner. Assumptions-free limits, based on top flavor violation at the LHC, are
then obtained. In the absence of signal, with 100 fb^{-1} of data, the LHC will
exclude weakly coupled (strongly coupled) new physics up to a scale of 0.6 TeV
(7.6 TeV), while at present no general constraint can be set related to Delta
t=1 processes. LHC data will constrain Delta F=2 contributions via same-sign
tops signal, with a model independent exclusion region of 0.08 TeV (1.0 TeV).
However, in this case, stronger bounds are found from the study of CP violation
in D-bar D mixing with a scale of 0.57 TeV (7.2 TeV). In addition, we apply our
analysis to models of supersymmetry and warped extra dimension. The minimal
flavor violation framework is also discussed, where the formalism allows to
distinguish between the linear and generic non-linear limits within this class
of models.Comment: 24 pages, 6 figures. Some corrections and clarifications; references

Thermodynamics and Cosmological Constant of Non-Local Field Theories
  from p-Adic Strings

We develop the thermodynamics of field theories characterized by non-local
propagators. We analyze the partition function and main thermodynamic
properties arising from perturbative thermal loops. We focus on the p-adic
models associated with the tachyon phenomenology in string theories. We
reproduce well known features of these theories, but also obtain many new
results. In particular, we explain how to maintain consistency of such
non-local theories by avoiding the appearance of ghosts at finite temperature.
As a consequence of this fact, the vacuum energy in p-adic theories becomes
positive. It is also hierarchically suppressed, and we explore the parameter
space where it is consistent with the observed value of the cosmological
constant.Comment: 34 pages, 11 figure
A Geometric Approach to CP Violation: Applications to the MCPMFV SUSY
  Model

We analyze the constraints imposed by experimental upper limits on electric
dipole moments (EDMs) within the Maximally CP- and Minimally Flavour-Violating
(MCPMFV) version of the MSSM. Since the MCPMFV scenario has 6 non-standard
CP-violating phases, in addition to the CP-odd QCD vacuum phase \theta_QCD,
cancellations may occur among the CP-violating contributions to the three
measured EDMs, those of the Thallium, neutron and Mercury, leaving open the
possibility of relatively large values of the other CP-violating observables.
We develop a novel geometric method that uses the small-phase approximation as
a starting point, takes the existing EDM constraints into account, and enables
us to find maximal values of other CP-violating observables, such as the EDMs
of the Deuteron and muon, the CP-violating asymmetry in b --> s \gamma decay,
and the B_s mixing phase. We apply this geometric method to provide upper
limits on these observables within specific benchmark supersymmetric scenarios,
including extensions that allow for a non-zero \theta_QCD.Comment: 34 pages, 16 eps figures, to appear in JHE
Cartan-Weyl 3-algebras and the BLG Theory I: Classification of
  Cartan-Weyl 3-algebras

As Lie algebras of compact connected Lie groups, semisimple Lie algebras have
wide applications in the description of continuous symmetries of physical
systems. Mathematically, semisimple Lie algebra admits a Cartan-Weyl basis of
generators which consists of a Cartan subalgebra of mutually commuting
generators H_I and a number of step generators E^\alpha that are characterized
by a root space of non-degenerate one-forms \alpha. This simple decomposition
in terms of the root space allows for a complete classification of semisimple
Lie algebras. In this paper, we introduce the analogous concept of a
Cartan-Weyl Lie 3-algebra. We analyze their structure and obtain a complete
classification of them. Many known examples of metric Lie 3-algebras (e.g. the
Lorentzian 3-algebras) are special cases of the Cartan-Weyl 3-algebras. Due to
their elegant and simple structure, we speculate that Cartan-Weyl 3-algebras
may be useful for describing some kinds of generalized symmetries. As an
application, we consider their use in the Bagger-Lambert-Gustavsson (BLG)
theory.Comment: LaTeX. 34 pages.v2. deleted some distracting paragraphs in the

A closer look at string resonances in dijet events at the LHC

The first string excited state can be observed as a resonance in dijet
invariant mass distributions at the LHC, if the scenario of low-scale string
with large extra dimensions is realized. A distinguished property of the dijet
resonance by string excited states from that the other "new physics" is that
many almost degenerate states with various spin compose a single resonance
structure. It is examined that how we can obtain evidences of low-scale string
models through the analysis of angular distributions of dijet events at the
LHC. Some string resonance states of color singlet can obtain large mass shifts
through the open string one-loop effect, or through the mixing with closed
string states, and the shape of resonance structure can be distorted. Although
the distortion is not very large (10% for the mass squared), it might be able
to observe the effect at the LHC, if gluon jets and quark jets could be
distinguished in a certain level of efficiency.Comment: 12 pages, 8 figure
Revealing the electroweak properties of a new scalar resonance

One or more new heavy resonances may be discovered in experiments at the CERN
Large Hadron Collider. In order to determine if such a resonance is the
long-awaited Higgs boson, it is essential to pin down its spin, CP, and
electroweak quantum numbers. Here we describe how to determine what role a
newly-discovered neutral CP-even scalar plays in electroweak symmetry breaking,
by measuring its relative decay rates into pairs of electroweak vector bosons:
WW, ZZ, \gamma\gamma, and Z\gamma. With the data-driven assumption that
electroweak symmetry breaking respects a remnant custodial symmetry, we perform
a general analysis with operators up to dimension five. Remarkably, only three
pure cases and one nontrivial mixed case need to be disambiguated, which can
always be done if all four decay modes to electroweak vector bosons can be
observed or constrained. We exhibit interesting special cases of Higgs
look-alikes with nonstandard decay patterns, including a very suppressed
branching to WW or very enhanced branchings to \gamma\gamma and Z\gamma. Even
if two vector boson branching fractions conform to Standard Model expectations
for a Higgs doublet, measurements of the other two decay modes could unmask a
Higgs imposter.Comment: 23 pages, two figures; v2: minor revision and version to appear in

Violation of the phase space general covariance as a diffeomorphism
  anomaly in quantum mechanics

We consider a topological quantum mechanics described by a phase space path
integral and study the 1-dimensional analog for the path integral
representation of the Kontsevich formula. We see that the naive bosonic
integral possesses divergences, that it is even naively non-invariant and thus
is ill-defined. We then consider a super-extension of the theory which
eliminates the divergences and makes the theory naively invariant. This
super-extension is equivalent to the correct choice of measure and was
discussed in the literature. We then investigate the behavior of this extended
theory under diffeomorphisms of the extended phase space and despite of its
naive invariance find out that the theory possesses anomaly under nonlinear
diffeomorphisms. We localize the origin of the anomaly and calculate the lowest
nontrivial anomalous contribution.Comment: 36 page
Deep inelastic scattering for vector mesons in holographic D4-D8 model

We study deep inelastic scattering for vector and axial vector mesons in the
holographic D4-D8 brane model. We consider tree level contributions with one
particle in the final hadronic state. We obtain the unpolarized structure
functions F1 and F2 for the rho and a1 mesons for q2 < 80 GeV2 and 0.2 < x < 1.
We find that the ratio F2/(2xF1) is approximately equal to one for some ranges
of x and q2, satisfying the Callan-Gross relation.Comment: 15 pages, 4 tables, 8 figures. V2: we added explanations about

Global SO(10) F-theory GUTs

Making use of toric geometry we construct a class of global F-theory GUT
models. The base manifolds are blowups of Fano threefolds and the Calabi-Yau
fourfold is a complete intersection of two hypersurfaces. We identify possible
GUT divisors and construct SO(10) models on them using the spectral cover
construction. We use a split spectral cover to generate chiral matter on the 10
curves in order to get more degrees of freedom in phenomenology. We use abelian
flux to break SO(10) to SU(5)\times U(1) which is interpreted as a flipped
SU(5) model. With the GUT Higgses in the SU(5)\times U(1) model it is possible
to further break the gauge symmetry to the Standard Model. We present several
phenomenologically attractive examples in detail.Comment: 58 pages, modified models, added references, corrected typo
Holography and the sound of criticality

Using gauge/gravity duality techniques, we discuss the sound-channel retarded
correlators of vector and tensor conserved currents in a class of
$(2+1)$-dimensional strongly-coupled field theories at zero temperature and
finite charge density, assumed to be holographically dual to the extremal
Reissner-Nordstr\"{o}m AdS$_4$ black hole. Using a combination of analytical
and numerical methods, we determine the quasinormal mode spectrum at finite
momentum for the coupled gravitational and electromagnetic perturbations, and
discuss the appropriate choice of gauge-invariant variables (master fields) in
order for the black hole quasinormal frequencies to reproduce the field theory
spectrum. We discuss the role of the near horizon AdS$_{2}$ geometry in
determining the low-frequency behavior of retarded correlators in the boundary
theory, and comment on the emergence of criticality in the IR. In addition, we
establish the existence of a sound mode at zero temperature and compute the
speed of sound and sound attenuation constant numerically, obtaining a result
consistent with the expectations from the zero temperature limit of
hydrodynamics. The dispersion relation of higher resonances is also
investigated.Comment: 36 pages, 15 figures, PDFLaTeX; v2, corrected typos and figure

R-parity violating resonant stop production at the Large Hadron Collider

We have investigated the resonant production of a stop at the Large Hadron
Collider, driven by baryon number violating interactions in supersymmetry. We
work in the framework of minimal supergravity models with the lightest
neutralino being the lightest supersymmetric particle which decays within the
detector. We look at various dilepton and trilepton final states, with or
without b-tags. A detailed background simulation is performed, and all possible
decay modes of the lighter stop are taken into account. We find that higher
stop masses are sometimes easier to probe, through the decay of the stop into
the third or fourth neutralino and their subsequent cascades. We also comment
on the detectability of such signals during the 7 TeV run, where, as expected,
only relatively light stops can be probed. Our conclusion is that the resonant
process may be probed, at both 10 and 14 TeV, with the R-parity violating
coupling {\lambda}"_{312} as low as 0.05, for a stop mass of about 1 TeV. The
possibility of distinguishing between resonant stop production and
pair-production is also discussed.Comment: 20 pages, 4 figures, 6 tables; Version accepted by JHE
Broken R-Parity in the Sky and at the LHC

Supersymmetric extensions of the Standard Model with small R-parity and
lepton number violating couplings are naturally consistent with primordial
nucleosynthesis, thermal leptogenesis and gravitino dark matter. We consider
supergravity models with universal boundary conditions at the grand unification
scale, and scalar tau-lepton or bino-like neutralino as next-to-lightest
superparticle (NLSP). Recent Fermi-LAT data on the isotropic diffuse gamma-ray
flux yield a lower bound on the gravitino lifetime. Comparing two-body
gravitino and neutralino decays we find a lower bound on a neutralino NLSP
decay length, $c \tau_{\chi^0_1} \gsim 30 cm$. Together with gravitino and
neutralino masses one obtains a microscopic determination of the Planck mass.
For a stau-NLSP there exists no model-independent lower bound on the decay
length. Here the strongest bound comes from the requirement that the
cosmological baryon asymmetry is not washed out, which yields $c
\tau_{\tilde\tau_1} \gsim 4 mm$. However, without fine-tuning of parameters,
one finds much larger decay lengths. For typical masses, $m_{3/2} \sim 100 GeV$
and $m_{NLSP} \sim 150 GeV$, the discovery of a photon line with an intensity
close to the Fermi-LAT limit would imply a decay length $c\tau_{NLSP}$ of
several hundred meters, which can be measured at the LHC.Comment: 30 pages, 8 figures; v2: published version, reference adde
Mathieu Moonshine in the elliptic genus of K3

It has recently been conjectured that the elliptic genus of K3 can be written
in terms of dimensions of Mathieu group M24 representations. Some further
evidence for this idea was subsequently found by studying the twining genera
that are obtained from the elliptic genus upon replacing dimensions of Mathieu
group representations by their characters. In this paper we find explicit
formulae for all (remaining) twining genera by making an educated guess for
their general modular properties. This allows us to identify the decomposition
of all expansion coefficients in terms of dimensions of M24-representations.
For the first 500 coefficients we verify that the multiplicities with which
these representations appear are indeed all non-negative integers. This
represents very compelling evidence in favour of the conjecture.Comment: 23 pages; an error corrected, references update
Quantum Hall Effect in a Holographic Model

We consider a holographic description of a system of strongly coupled
fermions in 2+1 dimensions based on a D7-brane probe in the background of
D3-branes, and construct stable embeddings by turning on worldvolume fluxes. We
study the system at finite temperature and charge density, and in the presence
of a background magnetic field. We show that Minkowski-like embeddings that
terminate above the horizon describe a family of quantum Hall states with
filling fractions that are parameterized by a single discrete parameter. The
quantization of the Hall conductivity is a direct consequence of the
topological quantization of the fluxes. When the magnetic field is varied
relative to the charge density away from these discrete filling fractions, the
embeddings deform continuously into black-hole-like embeddings that enter the
horizon and that describe metallic states. We also study the thermodynamics of
this system and show that there is a first order phase transition at a critical
temperature from the quantum Hall state to the metallic state.Comment: v2: 27 pages, 12 figures. There is a major revision in the
  quantitative analysis. The qualitative results and conclusions are unchanged,
  with one exception: we show that the quantum Hall state embeddings, which
  exist for discrete values of the filling fraction, deform continuously into
  metallic state embeddings away from these filling fraction
The Leading Quantum Corrections to Stringy Kahler Potentials

The structure of stringy quantum corrections to four-dimensional effective
theories is particularly interesting for string phenomenology and attempts to
stabilize moduli. We consider the heterotic string compactified on a Calabi-Yau
space. For this case, we compute the leading corrections to the kinetic terms
of moduli fields. The structure of these corrections is largely dictated by the
underlying higher-dimensional extended supersymmetry. We find corrections
generically of order (alpha')^2 rather than of order (alpha')^3 found in type
II compactifications or heterotic compactifications with the standard
embedding. We explore the implications of these corrections for breaking
no-scale structure.Comment: 33 pages, LaTeX; modified section
Long-Lived Neutralino NLSPs

We investigate the collider signatures of heavy, long-lived, neutral
particles that decay to charged particles plus missing energy. Specifically, we
focus on the case of a neutralino NLSP decaying to Z and gravitino within the
context of General Gauge Mediation. We show that a combination of searches
using the inner detector and the muon spectrometer yields a wide range of
potential early LHC discoveries for NLSP lifetimes ranging from 10^(-1)-10^5
mm. We further show that events from Z(l+l-) can be used for detailed kinematic
reconstruction, leading to accurate determinations of the neutralino mass and
lifetime. In particular, we examine the prospects for detailed event study at
ATLAS using the ECAL (making use of its timing and pointing capabilities)
together with the TRT, or using the muon spectrometer alone. Finally, we also
demonstrate that there is a region in parameter space where the Tevatron could
potentially discover new physics in the delayed Z(l+l-)+MET channel. While our
discussion centers on gauge mediation, many of the results apply to any
scenario with a long-lived neutral particle decaying to charged particles.Comment: 31 pages, 12 figure
Towards 't Hooft parameter corrections to charge transport in
  strongly-coupled plasma

We study R-charge transport in a wide class of strongly-coupled
supersymmetric plasmas at finite temperature with 't Hooft coupling
corrections. To achieve this, we use the gauge/string duality and include the
full set of order(\alpha'^3) corrections to the supergravity backgrounds given
at zeroth order by the direct product of the AdS-Schwarzschild black hole with
a five-dimensional compact Einstein manifold. On general grounds, the reduction
leads to a large number of higher derivative operators, which we reduce using
the symmetries of the solution. We are left with a universal set of operators
whose coefficients can in principle be fixed by carrying out an explicit
compactification. We apply our results to the computation of the R-charge
conductivity of the supersymmetric plasma at finite yet strong coupling.Comment: 23 page
de Sitter Thick Brane Solution in Weyl Geometry

In this paper, we consider a de Sitter thick brane model in a pure geometric
Weyl integrable five-dimensional space-time, which is a generalization of
Riemann geometry and is invariant under a so-called Weyl rescaling. We find a
solution of this model via performing a conformal transformation to map the
Weylian structure into a familiar Riemannian one with a conformal metric. The
metric perturbations of the model are discussed. For gravitational
perturbation, we get the effective modified P$\ddot{\text{o}}$schl-Teller
potential in corresponding Schr$\ddot{\text{o}}$dinger equation for
Kaluza-Klein (KK) modes of the graviton. There is only one bound state, which
is a normalizable massless zero mode and represents a stable 4-dimensional
graviton. Furthermore, there exists a mass gap between the massless mode and
continuous KK modes. We also find that the model is stable under the scalar
perturbation in the metric. The correction to the Newtonian potential on the
brane is proportional to $e^{-3 r \beta/2}/r^2$, where $\beta$ is the de Sitter
parameter of the brane. This is very different from the correction caused by a
volcano-like effective potential.Comment: 24 pages, 13 figures, published versio
Regularization of identity based solution in string field theory

We demonstrate that an Erler-Schnabl type solution in cubic string field
theory can be naturally interpreted as a gauge invariant regularization of an
identity based solution. We consider a solution which interpolates between an
identity based solution and ordinary Erler-Schnabl one. Two gauge invariant
quantities, the classical action and the closed string tadpole, are evaluated
for finite value of the gauge parameter. It is explicitly checked that both of
them are independent of the gauge parameter.Comment: 9 pages, minor typos corrected and references adde
Relating Gauge Theories via Gauge/Bethe Correspondence

In this note, we use techniques from integrable systems to study relations
between gauge theories. The Gauge/Bethe correspondence, introduced by Nekrasov
and Shatashvili, identifies the supersymmetric ground states of an N=(2,2)
supersymmetric gauge theory in two dimensions with the Bethe states of a
quantum integrable system. We make use of this correspondence to relate three
different quiver gauge theories which correspond to three different
formulations of the Bethe equations of an integrable spin chain called the tJ
model.Comment: 30 pages, published in JHEP. LaTeX problem correcte
Hidden Conformal Symmetry of Extremal Kerr-Bolt Spacetimes

We show that extremal Kerr-Bolt spacetimes have a hidden conformal symmetry.
In this regard, we consider the wave equation of a massless scalar field
propagating in extremal Kerr-Bolt spacetimes and find in the "near region", the
wave equation in extremal limit can be written in terms of the $SL(2,R)$
quadratic Casimir. Moreover, we obtain the microscopic entropy of the extremal
Kerr-Bolt spacetimes also we calculate the correlation function of a
near-region scalar field and find perfect agreement with the dual 2D CFT.Comment: 13 page
