From weak coupling to spinning strings

We identify the gauge theory dual of a spinning string of minimal energy with
spins S_1, S_2 on AdS_5 and charge J on S^5. For this purpose we focus on a
certain set of local operators with two different types of covariant
derivatives acting on complex scalar fields. We analyse the corresponding
nested Bethe equations for the ground states in the limit of large spins. The
auxiliary Bethe roots form certain string configurations in the complex plane,
which enable us to derive integral equations for the leading and sub-leading
contribution to the anomalous dimension. The results can be expressed through
the observables of the sl(2) sub-sector, i.e. the cusp anomaly f(g) and the
virtual scaling function B_L(g), rendering the strong-coupling analysis
straightforward. Furthermore, we also study a particular sub-class of these
operators specialising to a scaling limit with finite values of the second spin
at weak and strong coupling.Comment: 23 pages, 3 figures, minor changes, references adde
New-physics contributions to the forward-backward asymmetry in B -> K*
  mu+ mu-

We study the forward-backward asymmetry (AFB) and the differential branching
ratio (DBR) in B -> K* mu+ mu- in the presence of new physics (NP) with
different Lorentz structures. We consider NP contributions from vector-axial
vector (VA), scalar-pseudoscalar (SP), and tensor (T) operators, as well as
their combinations. We calculate the effects of these new Lorentz structures in
the low-q^2 and high-q^2 regions, and explain their features through analytic
approximations. We find two mechanisms that can give a significant deviation
from the standard-model predictions, in the direction indicated by the recent
measurement of AFB by the Belle experiment. They involve the addition of the
following NP operators: (i) VA, or (ii) a combination of SP and T (slightly
better than T alone). These two mechanisms can be distinguished through
measurements of DBR in B -> K* mu+ mu- and AFB in B -> K mu+ mu-.Comment: 33 pages, revtex, 9 figures. Paper originally submitted with the

Exploring Positive Monad Bundles And A New Heterotic Standard Model

A complete analysis of all heterotic Calabi-Yau compactifications based on
positive two-term monad bundles over favourable complete intersection
Calabi-Yau threefolds is performed. We show that the original data set of about
7000 models contains 91 standard-like models which we describe in detail. A
closer analysis of Wilson-line breaking for these models reveals that none of
them gives rise to precisely the matter field content of the standard model. We
conclude that the entire set of positive two-term monads on complete
intersection Calabi-Yau manifolds is ruled out on phenomenological grounds. We
also take a first step in analyzing the larger class of non-positive monads. In
particular, we construct a supersymmetric heterotic standard model within this
class. This model has the standard model gauge group and an additional
U(1)_{B-L} symmetry, precisely three families of quarks and leptons, one pair
of Higgs doublets and no anti-families or exotics of any kind.Comment: 48 page
Testing Yukawa-unified SUSY during year 1 of LHC: the role of multiple
  b-jets, dileptons and missing E_T

We examine the prospects for testing SO(10) Yukawa-unified supersymmetric
models during the first year of LHC running at \sqrt{s}= 7 TeV, assuming
integrated luminosity values of 0.1 to 1 fb^-1. We consider two cases: the
Higgs splitting (HS) and the D-term splitting (DR3) models. Each generically
predicts light gluinos and heavy squarks, with an inverted scalar mass
hierarchy. We hence expect large rates for gluino pair production followed by
decays to final states with large b-jet multiplicity. For 0.2 fb^-1 of
integrated luminosity, we find a 5 sigma discovery reach of m(gluino) ~ 400 GeV
even if missing transverse energy, E_T^miss, is not a viable cut variable, by
examining the multi-b-jet final state. A corroborating signal should stand out
in the opposite-sign (OS) dimuon channel in the case of the HS model; the DR3
model will require higher integrated luminosity to yield a signal in the OS
dimuon channel. This region may also be probed by the Tevatron with 5-10 fb^-1
of data, if a corresponding search in the multi-b+ E_T^miss channel is
performed. With higher integrated luminosities of ~1 fb^-1, using E_T^miss plus
a large multiplicity of b-jets, LHC should be able to discover Yukawa-unified
SUSY with m(gluino) up to about 630 GeV. Thus, the year 1 LHC reach for
Yukawa-unified SUSY should be enough to either claim a discovery of the gluino,
or to very nearly rule out this class of models, since higher values of
m(gluino) lead to rather poor Yukawa unification.Comment: 32 pages including 31 EPS figure
Near-horizon analysis of D=5 BPS black holes and rings

A comprehensive analysis is presented based exclusively on near-horizon data
to determine the attractor equations and the entropy of BPS black holes and
rings in five space-time dimensions, for a Lagrangian invariant under eight
supersymmetries with higher-derivative couplings. For spinning black holes the
results only partially agree with the results of previous work, where often
additional input was used beyond the near-horizon behaviour. A number of
discrepancies remains, for example, pertaining to small black holes and to
large spinning black holes, which are related to the presence of the
higher-derivative couplings. Arguments are presented to explain some of them.
For the black rings, the analysis is intricate due to the presence of
Chern-Simons terms and due to the fact that the gauge fields are not globally
defined. The contributions from the higher-derivative couplings take a
systematic form in line with expectations based on a variety of arguments.Comment: 52 pages, 2 figures, PDFLaTeX, v2: typos corrected, version to appear

A supermatrix model for N=6 super Chern-Simons-matter theory

We construct the Wilson loop operator of N=6 super Chern-Simons-matter which
is invariant under half of the supercharges of the theory and is dual to the
simplest macroscopic open string in AdS_4 x CP^3. The Wilson loop couples, in
addition to the gauge and scalar fields of the theory, also to the fermions in
the bi-fundamental representation of the U(N) x U(M) gauge group. These
ingredients are naturally combined into a superconnection whose holonomy gives
the Wilson loop, which can be defined for any representation of the supergroup
U(N|M). Explicit expressions for loops supported along an infinite straight
line and along a circle are presented. Using the localization calculation of
Kapustin et al. we show that the circular loop is computed by a supermatrix
model and discuss the connection to pure Chern-Simons theory with supergroup
U(N|M).Comment: 23 page
Holographic Anyons in the ABJM Theory

We consider the holographic anyons in the ABJM theory from three different
aspects of AdS/CFT correspondence. First, we identify the holographic anyons by
using the field equations of supergravity, including the Chern-Simons terms of
the probe branes. We find that the composite of Dp-branes wrapped over CP3 with
the worldvolume magnetic fields can be the anyons. Next, we discuss the
possible candidates of the dual anyonic operators on the CFT side, and find the
agreement of their anyonic phases with the supergravity analysis. Finally, we
try to construct the brane profile for the holographic anyons by solving the
equations of motion and Killing spinor equations for the embedding profile of
the wrapped branes. As a by product, we find a BPS spiky brane for the dual
baryons in the ABJM theory.Comment: 1+33 pages, 3 figures; v2 discussion for D4-D6 case added, references

Quantum Criticality and Holographic Superconductors in M-theory

We present a consistent Kaluza-Klein truncation of D=11 supergravity on an
arbitrary seven-dimensional Sasaki-Einstein space (SE_7) to a D=4 theory
containing a metric, a gauge-field, a complex scalar field and a real scalar
field. We use this D=4 theory to construct various black hole solutions that
describe the thermodynamics of the d=3 CFTs dual to skew-whiffed AdS_4 X SE_7
solutions. We show that these CFTs have a rich phase diagram, including
holographic superconductivity with, generically, broken parity and time
reversal invariance. At zero temperature the superconducting solutions are
charged domain walls with a universal emergent conformal symmetry in the far
infrared.Comment: 52 pages, 16 figures, 3 appendices; minor changes, version to be

Effects of Top-quark Compositeness on Higgs Boson Production at the LHC

Motivated by the possibility that the right-handed top-quark (t_R) is
composite, we discuss the effects of dimension-six operators on the Higgs boson
production at the LHC. When t_R is the only composite particle among the
Standard Model (SM) particles, the (V+A)\otimes (V+A) type four-top-quark
contact interaction is expected to have the largest coefficient among the
dimension-six operators, according to the Naive Dimensional Analysis (NDA). We
find that, to lowest order in QCD and other SM interactions, the cross section
of the SM Higgs boson production via gluon fusion does not receive corrections
from one insertion of the new contact interaction vertex. We also discuss the
effects of other dimension-six operators whose coefficients are expected to be
the second and the third largest from NDA. We find that the operator which
consists of two t_R's and two SM Higgs boson doublets can recognizably change
the Higgs boson production cross section from the SM prediction if the cut-off
scale is \sim 1TeV.Comment: 12 pages, 7 figures. v2: explanations improved in Section 3, other

Tachyons in Throat Cosmology

Tachyonic 5d scalars are generically present in Randall-Sundrum-like models.
In particular, they are known to be part of the 5d effective description of the
Klebanov-Strassler throat. When moving from the IR to the UV region, the 5d
bulk profile of Kaluza-Klein excitations of tachyons decays more slowly than
that of massless scalars or the graviton. As a result, tachyons in many cases
dominate the coupling between IR- and UV-localized sectors, leading to a very
significant enhancement of energy-transfer or decay rates from the IR to the
UV. This can dramatically affect the reheating of the Standard Model after
brane inflation and the decay of throat dark matter.Comment: 37 pages, 4 figures; v2: references adde
Open and Closed String Vertices for branes with magnetic field and
  T-duality

We discuss carefully the vertices which describe the dipole open strings and
closed strings on a D-brane with magnetic flux on a torus. Translation
invariance along closed cycles forces surprisingly closed string vertices
written in open string formalism to acquire Chan-Paton like matrices. Moreover
the one loop amplitudes have a single trace for the part of gauge group with
the magnetic flux. These peculiarities are also required by consistency of the
action of T-duality in the open string sector. In this way we can show to all
orders in perturbation theory the equivalence of the T-dual open string
theories, gravitational interactions included. We provide also a new and direct
derivation of the bosonic boundary state in presence of constant magnetic and
Kalb-Ramond background based on Sciuto-Della Selva-Saito vertex formalism.Comment: 63 pages, 7 figure
Half-BPS Solutions locally asymptotic to AdS_3 x S^3 and interface
  conformal field theories

Type IIB superstring theory has AdS_3 x S^3 x M_4 (where the manifold M_4 is
either K_3 or T^4) solutions which preserve sixteen supersymmetries. In this
paper we consider half-BPS solutions which are locally asymptotic to AdS_3 x
S^3 x M_4 and preserve eight of the sixteen supersymmetries. We reduce the BPS
equations and the Bianchi identity for the self-dual five-form field to a set
of four differential equations. The complete local solution can be
parameterized in terms of two harmonic and two holomorphic functions and all
bosonic fields have explicit expressions in terms of these functions.
  We analyze the conditions for global regularity and construct new half-BPS
Janus-solutions which have two asymptotic AdS_3 regions. In addition, our
analysis proves the global regularity of a class of solutions with more than
two asymptotic AdS_3 regions. Finally, we discuss the dual interpretation as a
supersymmetric interface theory for the half-BPS Janus solutions carrying only
Ramond-Ramond three-form charge.Comment: 61 pages, 14 figures, pdflatex, reference added, minor changes and

Transport coefficients, membrane couplings and universality at
  extremality

We present an efficient method for computing the zero frequency limit of
transport coefficients in strongly coupled field theories described
holographically by higher derivative gravity theories. Hydrodynamic parameters
such as shear viscosity and conductivity can be obtained by computing residues
of poles of the off-shell lagrangian density. We clarify in which sense these
coefficients can be thought of as effective couplings at the horizon, and
present analytic, Wald-like formulae for the shear viscosity and conductivity
in a large class of general higher derivative lagrangians. We show how to apply
our methods to systems at zero temperature but finite chemical potential. Our
results imply that such theories satisfy $\eta/s=1/4\pi$ universally in the
Einstein-Maxwell sector. Likewise, the zero frequency limit of the real part of
the conductivity for such systems is shown to be universally zero, and we
conjecture that higher derivative corrections in this sector do not modify this
result to all orders in perturbation theory.Comment: 29 pages, v2: Small text changes for clarity, typos correcte
Particle Kinematics in Horava-Lifshitz Gravity

We study the deformed kinematics of point particles in the Horava theory of
gravity. This is achieved by considering particles as the optical limit of
fields with a generalized Klein-Gordon action. We derive the deformed geodesic
equation and study in detail the cases of flat and spherically symmetric
(Schwarzschild-like) spacetimes. As the theory is not invariant under local
Lorenz transformations, deviations from standard kinematics become evident even
for flat manifolds, supporting superluminal as well as massive luminal
particles. These deviations from standard behavior could be used for
experimental tests of this modified theory of gravity.Comment: Added references, corrected a typing erro
Relativistic CFT Hydrodynamics from the Membrane Paradigm

We use the membrane paradigm to analyze the horizon dynamics of a uniformly
boosted black brane in a (d+2)-dimensional asymptotically Anti-de-Sitter
space-time and a Rindler acceleration horizon in (d+2)-dimensional Minkowski
space-time. We show that in these cases the horizon dynamics is governed by the
relativistic CFT hydrodynamics equations. The fluid velocity and temperature
correspond to the normal to the horizon and to the surface gravity,
respectively. The second law of thermodynamics for the fluid is mapped into the
area increase theorem of General Relativity. The analysis is applicable, in
general, to perturbations around a stationary horizon, when the scale of
variations of the macroscopic fields is much larger than the inverse of the
temperature. We show that the non-relativistic limit of our analysis yields the
incompressible Navier-Stokes equations.Comment: 26 pages; v2: more discussion of Landau gauge, fixed typos, added

Two-Loop Spectroscopy of Short ABJM Operators

We study the spectrum of anomalous dimensions of short operators in planar
ABJM theory at two loops. Specifically we develop a method for solving the
OSp(6|4) Bethe ansatz equations for a certain class of unpaired length-4 states
with arbitrarily high number of excitations, and apply it to identify three new
sequences of rational eigenvalues. Results for low-lying paired states in the
OSp(4|2) sector are obtained by direct diagonalization of the spin chain
Hamiltonian. We also study the SL(2|1) sector and identify the set of states
that corresponds to the SL(2)-like Bethe ansatz of Gromov and Vieira. Finally
we extend part of our analysis to length-6 operators.Comment: 35 pages, 3 figures. v2:Minor clarifications added and typos

Fermions and noncommutative emergent gravity II: Curved branes in extra
  dimensions

We study fermions coupled to Yang-Mills matrix models from the point of view
of emergent gravity. The matrix model Dirac operator provides an appropriate
coupling for fermions to the effective gravitational metric for general branes
with nontrivial embedding, albeit with a non-standard spin connection. This
generalizes previous results for 4-dimensional matrix models. Integrating out
the fermions in a nontrivial geometrical background induces indeed the
Einstein-Hilbert action of the effective metric, as well as additional terms
which couple the Poisson tensor to the Riemann tensor, and a dilaton-like term.Comment: 34 pages; minor change
Symmetries of topological gravity with torsion in the hamiltonian and
  lagrangian formalisms

A systematic analysis of the symmetries of topological 3D gravity with
torsion and a cosmological term, in the first order formalism, has been
performed in details - both in the hamiltonian and lagrangian formalisms. This
illuminates the connection between the symmetries of curved spacetime
(diffeomorphisms plus local Lorentz transformations) with the Poincare gauge
transformations. The Poincare gauge symmetries of the action are shown to be
inequivalent to its gauge symmetries. Finally, the complete analysis is
compared with the metric formulation where the diffeomorphism symmetry is shown
to be equivalent to the gauge symmetry.Comment: 27 pages, PDFLaTeX; Minor corrections, version accepted for

Complete classification of Minkowski vacua in generalised flux models

We present a complete and systematic analysis of the Minkowski extrema of the
N=1, D=4 Supergravity potential obtained from type II orientifold models that
are T-duality invariant, in the presence of generalised fluxes. Based on our
previous work on algebras spanned by fluxes, and the so-called no-go theorems
on the existence of Minkowski and/or de Sitter vacua, we perform a partly
analytic, partly numerical analysis of the promising cases previously hinted.
We find that the models contain Minkowski extrema with one tachyonic direction.
Moreover, those models defined by the Supergravity algebra so(3,1)^2 also
contain Minkowski/de Sitter minima that are totally stable. All Minkowski
solutions, stable or not, interpolate between points in parameter space where
one or several of the moduli go to either zero or infinity, the so-called
singular points. We finally reinterpret our results in the language of type IIA
flux models, in order to show explicitly the contribution of the different
sources of potential energy to the extrema found. In particular, the cases of
totally stable Minkowski/de Sitter vacua require of the presence of
non-geometric fluxes.Comment: 29 pages, 17 figures, 1 tabl
Weierstrass meets Enriques

We study in detail the degeneration of K3 to T^4/Z_2. We obtain an explicit
embedding of the lattice of collapsed cycles of T^4/Z_2 into the lattice of
integral cycles of K3 in two different ways. Our first method exploits the
duality to the heterotic string on T^3. This allows us to describe the
degeneration in terms of Wilson lines. Our second method is based on the
blow-up of T^4/Z_2. From this blow-up, we directly construct the full lattice
of integral cycles of K3. Finally, we use our results to describe the action of
the Enriques involution on elliptic K3 surfaces, finding that a Weierstrass
model description is consistent with the Enriques involution only in the
F-theory limit.Comment: 35 pages, 9 figure
Theoretical survey of tidal-charged black holes at the LHC

We analyse a family of brane-world black holes which solve the effective
four-dimensional Einstein equations for a wide range of parameters related to
the unknown bulk/brane physics. We first constrain the parameters using known
experimental bounds and, for the allowed cases, perform a numerical analysis of
their time evolution, which includes accretion through the Earth. The study is
aimed at predicting the typical behavior one can expect if such black holes
were produced at the LHC. Most notably, we find that, under no circumstances,
would the black holes reach the (hazardous) regime of Bondi accretion.
Nonetheless, the possibility remains that black holes live long enough to
escape from the accelerator (and even from the Earth's gravitational field) and
result in missing energy from the detectors.Comment: RevTeX4, 12 pages, 4 figures, 5 tables, minor changes to match the

Localization of Matters on Anti-de Sitter Thick Branes

By presenting the mass-independent potentials of the Kaluza-Klein (KK) modes
in the corresponding Schr\"{o}dinger equations, we investigate the localization
and mass spectra of various bulk matter fields on an AdS thick brane. For a
spin 0 scalar $\Phi$ coupled with itself and the domain-wall-forming field
$\phi$ via a coupling potential
  $V=(\lambda \phi^{2}-u^{2})\Phi^{2}+\tau\Phi^{4}$, the localization and
spectrum are decided by a critical coupling constant $\lambda_{0}$. When
$\lambda>\lambda_0$, the potential of the scalar KK modes in the corresponding
Schr\"{o}dinger equation tends to infinite when far away from the brane, which
results in that there exist infinite discrete scalar bound KK states, and the
massless modes could be trapped on the AdS brane by fine-tuning of parameters.
When $\lambda<\lambda_0$, the potential of the scalar KK modes tends to
negative infinite when far away from the brane, hence there does not exist any
scalar bound KK state. For a spin 1 vector, the situation is same like the
scalar with a coupling constant $\lambda>\lambda_0$, but the zero mode can not
be localized on the brane. For a spin 1/2 fermion, we introduce the usual
Yukawa coupling $\eta\bar{\Psi}\phi\Psi$, and find that the localization of the
fermion is decided by a critical coupling constant $\eta_0$. For $\eta >
\eta_0$, the four-dimensional massless left chiral fermion and massive Dirac
fermions consisted of the pairs of coupled left-hand and right-hand KK modes
could be localized on the AdS brane, and the massive Dirac fermions have a set
of discrete mass spectrum. While for the case $0<\eta < \eta_{0}$, no
four-dimensional Dirac fermion can be localized on the AdS brane.Comment: 23 pages, 17 figures, published versio
Hydrodynamics of fundamental matter

First and second order transport coefficients are calculated for the strongly
coupled N=4 SYM plasma coupled to massless fundamental matter in the Veneziano
limit. The results, including among others the value of the bulk viscosity and
some relaxation times, are presented at next-to-leading order in the flavor
contribution. The bulk viscosity is found to saturate Buchel's bound. This
result is also captured by an effective single-scalar five-dimensional
holographic dual in the Chamblin-Reall class and it is suggested to hold, in
the limit of small deformations, for generic plasmas with gravity duals,
whenever the leading conformality breaking effects are driven by marginally
(ir)relevant operators. This proposal is then extended to other relations for
hydrodynamic coefficients, which are conjectured to be universal for every
non-conformal plasma with a dual Chamblin-Reall-like description. Our analysis
extends to any strongly coupled gauge theory describing the low energy dynamics
of Nc>>1 D3-branes at the tip of a generic Calabi-Yau cone. The fundamental
fields are added by means of 1<<Nf<<Nc homogeneously smeared D7-branes.Comment: 24 pages. V2: Important improvements in the discussion of the results
