Wave functions and correlation functions for GKP strings from
  integrability

We develop a general method of computing the contribution of the vertex
operators to the semi-classical correlation functions of heavy string states,
based on the state-operator correspondence and the integrable structure of the
system. Our method requires only the knowledge of the local behavior of the
saddle point configuration around each vertex insertion point and can be
applied to cases where the precise forms of the vertex operators are not known.
As an important application, we compute the contributions of the vertex
operators to the three-point functions of the large spin limit of the
Gubser-Klebanov-Polyakov (GKP) strings in $AdS_3$ spacetime, left unevaluated
in our previous work [arXiv:1110.3949] which initiated such a study. Combining
with the finite part of the action already computed previously and with the
newly evaluated divergent part of the action, we obtain finite three-point
functions with the expected dependence of the target space boundary coordinates
on the dilatation charge and the spin.Comment: 80 pages, 7 figures, v2: typos and minor errors corrected, a

Z' signals in polarised top-antitop final states

We study the sensitivity of top-antitop samples produced at all energy stages
of the Large Hadron Collider (LHC) to the nature of an underlying Z' boson, in
presence of full tree level standard model (SM) background effects and relative
interferences. We concentrate on differential mass spectra as well as both
spatial and spin asymmetries thereby demonstrating that exploiting combinations
of these observables will enable one to distinguish between sequential Z's and
those pertaining to Left-Right symmetric models as well as E6 inspired ones,
assuming realistic final state reconstruction efficiencies and error estimates.Comment: 21 pages, 6 colour figures, 10 table
Scalar geometry and masses in Calabi-Yau string models

We study the geometry of the scalar manifolds emerging in the no-scale sector
of Kahler moduli and matter fields in generic Calabi-Yau string
compactifications, and describe its implications on scalar masses. We consider
both heterotic and orientifold models and compare their characteristics. We
start from a general formula for the Kahler potential as a function of the
topological compactification data and study the structure of the curvature
tensor. We then determine the conditions for the space to be symmetric and show
that whenever this is the case the heterotic and the orientifold models give
the same scalar manifold. We finally study the structure of scalar masses in
this type of geometries, assuming that a generic superpotential triggers
spontaneous supersymmetry breaking. We show in particular that their behavior
crucially depends on the parameters controlling the departure of the geometry
from the coset situation. We first investigate the average sGoldstino mass in
the hidden sector and its sign, and study the implications on vacuum
metastability and the mass of the lightest scalar. We next examine the soft
scalar masses in the visible sector and their flavor structure, and study the
possibility of realizing a mild form of sequestering relying on a global
symmetry.Comment: 36 pages, no figure
Bounds on SCFTs from Conformal Perturbation Theory

The operator product expansion (OPE) in 4d (super)conformal field theory is
of broad interest, for both formal and phenomenological applications. In this
paper, we use conformal perturbation theory to study the OPE of nearly-free
fields coupled to SCFTs. Under fairly general assumptions, we show that the OPE
of a chiral operator of dimension $\Delta = 1+\epsilon$ with its complex
conjugate always contains an operator of dimension less than $2 \Delta$. Our
bounds apply to Banks-Zaks fixed points and their generalizations, as we
illustrate using several examples.Comment: 36 pages; v2: typos fixed, minor change
Notes on Emergent Gravity

Emergent gravity is aimed at constructing a Riemannian geometry from U(1)
gauge fields on a noncommutative spacetime. But this construction can be
inverted to find corresponding U(1) gauge fields on a (generalized) Poisson
manifold given a Riemannian metric (M, g). We examine this bottom-up approach
with the LeBrun metric which is the most general scalar-flat Kahler metric with
a U(1) isometry and contains the Gibbons-Hawking metric, the real heaven as
well as the multi-blown up Burns metric which is a scalar-flat Kahler metric on
C^2 with n points blown up. The bottom-up approach clarifies some important
issues in emergent gravity.Comment: v3; 29 pages, minor clarifications for locally conformal symplectic

Asymptotic Energy Dependence of Hadronic Total Cross Sections from
  Lattice QCD

The nonperturbative approach to soft high-energy hadron-hadron scattering,
based on the analytic continuation of Wilson-loop correlation functions from
Euclidean to Minkowskian theory, allows to investigate the asymptotic energy
dependence of hadron-hadron total cross sections in lattice QCD. In this paper
we will show, using best fits of the lattice data with proper functional forms
satisfying unitarity and other physical constraints, how indications emerge in
favor of a universal asymptotic high-energy behavior of the kind B log^2 s for
hadronic total cross sections.Comment: Revised and extended version; 29 pages, 4 figure
Seiberg-Witten Theories on Ellipsoids

We present a set of equations for a 4D Killing spinor which guarantees the
Seiberg-Witten theories on a curved background to be supersymmetric. The
equations involve an SU(2) gauge field and some auxiliary fields in addition to
the metric. Four-dimensional ellipsoids with U(1)xU(1) isometry are shown to
admit a supersymmetry if these additional fields are chosen appropriately. We
compute the partition function of general Seiberg-Witten theories on
ellipsoids, and the result suggests a correspondence with 2D Liouville or Toda
correlators with general coupling constant b.Comment: 1+27 pages, no figures. v2: references added, minor corrections.

Free energy v.s. Sasaki-Einstein volume for infinite families of M2-brane theories.

We investigate infinite families of 3d N=2  superconformal Chern-Simons quivers with an arbitrarily large number of gauge groups arising on M2-branes over toric CY4’s. These theories have the same matter content and superpotential of those on D3-branes probing cones over La,b,a Sasaki-Einstein manifolds. For all these infinite families, we explicitly show the correspondence between the free energy F on S3 and the volume of the 7-dimensional base of the associated CY4, even before extremization. Symmetries of the toric diagram are exploited for reducing the dimensionality of the space over which the volume of the Sasaki-Einstein manifold is extremized. Similarly, the space of trial R-charges of the gauge theory is constrained using symmetries of the quiver. Our results add to those existing in the literature, providing further support for the correspondence. We develop a lifting algorithm, based on the Type IIB realization of these theories, that takes from CY3’s to CY4’s and we use it to efficiently generate the models studied in the paper. Finally, we show that in all the infinite families we consider F2 can be expressed, even off-shell, as a quartic function in R-charges associated to certain 5-cycles. This suggests that a quartic formula on R-charges, analogous to a similar cubic function for the central charge a in 4d, exists for all toric toric CY4’s and we present some ideas regarding its general form
Network and Seiberg Duality

We define and study a new class of 4d N=1 superconformal quiver gauge
theories associated with a planar bipartite network. While UV description is
not unique due to Seiberg duality, we can classify the IR fixed points of the
theory by a permutation, or equivalently a cell of the totally non-negative
Grassmannian. The story is similar to a bipartite network on the torus
classified by a Newton polygon. We then generalize the network to a general
bordered Riemann surface and define IR SCFT from the geometric data of a
Riemann surface. We also comment on IR R-charges and superconformal indices of
our theories.Comment: 28 pages, 28 figures; v2: minor correction
Colored BPS pyramid partition functions, quivers and cluster transformations.

We investigate the connections between flavored quivers, dimer models, and BPS pyramids for generic toric Calabi-Yau threefolds from various perspectives. We introduce a purely field theoretic definition of both finite and infinite pyramids in terms of quivers with flavors. These pyramids are associated to the counting of BPS invariants for generic toric Calabi-Yau threefolds. We discuss how cluster transformations provide an efficient recursive method for computing pyramid partition functions and show that the recursion is equivalent to the multidimensional octahedron recurrence. Transitions between different pyramids are related to Seiberg dualities, and we offer complimentary characterizations of these transitions in terms of the motion of zonotopes and duality webs. Our methods apply to completely general geometries including those with vanishing 4-cycles, which are associated to chiral quivers, thus overcoming one of the main limitations in the existing literature. We illustrate our ideas with explicit results for the infinite family of La,b,c geometries, dP2, pseudo-dP2, and dP3. The counting of pyramid partitions for dP1 gives rise to the Somos-4 sequence, while dP2 and pseudo-dP2 generate the Somos-5 sequence. Our results for dP3 reproduce and extend those previously obtained for this theory, which were originally obtained from dimer shuffling
D3/D7 Quark-Gluon Plasma with Magnetically Induced Anisotropy

We study the effects of the temperature and of a magnetic field in the setup
of an intersection of D3/D7 branes, where a large number of D7 branes is
smeared in the transverse directions to allow for a perturbative solution in a
backreaction parameter. The magnetic field sources an anisotropy in the plasma,
and we investigate its physical consequences for the thermodynamics and energy
loss of particles probing the system. In particular we comment on the
stress-energy tensor of the plasma, the propagation of sound in the directions
parallel and orthogonal to the magnetic field, the drag force of a quark moving
through the medium and jet quenching.Comment: 29 pages + appendices, 5 figures. v2 Version to appear in JHEP, with

Integrand-Level Reduction of Loop Amplitudes by Computational Algebraic
  Geometry Methods

We present an algorithm for the integrand-level reduction of multi-loop
amplitudes of renormalizable field theories, based on computational algebraic
geometry. This algorithm uses (1) the Gr\"obner basis method to determine the
basis for integrand-level reduction, (2) the primary decomposition of an ideal
to classify all inequivalent solutions of unitarity cuts. The resulting basis
and cut solutions can be used to reconstruct the integrand from unitarity cuts,
via polynomial fitting techniques. The basis determination part of the
algorithm has been implemented in the Mathematica package, BasisDet. The
primary decomposition part can be readily carried out by algebraic geometry
softwares, with the output of the package BasisDet. The algorithm works in both
D=4 and $D=4-2\epsilon$ dimensions, and we present some two and three-loop
examples of applications of this algorithm.Comment: published version: typos corrected; more examples adde
Effective String Theory Revisited

We revisit the effective field theory of long relativistic strings such as
confining flux tubes in QCD. We derive the Polchinski-Strominger interaction by
a calculation in static gauge. This interaction implies that a non-critical
string which initially oscillates in one direction gets excited in orthogonal
directions as well. In static gauge no additional term in the effective action
is needed to obtain this effect. It results from a one-loop calculation using
the Nambu-Goto action. Non-linearly realized Lorentz symmetry is manifest at
all stages in dimensional regularization. We also explain that independent of
the number of dimensions non-covariant counterterms have to be added to the
action in the commonly used zeta-function regularization.Comment: 21 pages, 4 figures, v2: typo corrected, references added, published

Constraints on Fluid Dynamics from Equilibrium Partition Functions

We study the thermal partition function of quantum field theories on
arbitrary stationary background spacetime, and with arbitrary stationary
background gauge fields, in the long wavelength expansion. We demonstrate that
the equations of relativistic hydrodynamics are significantly constrained by
the requirement of consistency with any partition function. In examples at low
orders in the derivative expansion we demonstrate that these constraints
coincide precisely with the equalities between hydrodynamical transport
coefficients that follow from the local form of the second law of
thermodynamics. In particular we recover the results of Son and Surowka on the
chiral magnetic and chiral vorticity flows, starting from a local partition
function that manifestly reproduces the field theory anomaly, without making
any reference to an entropy current. We conjecture that the relations between
transport coefficients that follow from the second law of thermodynamics agree
to all orders in the derivative expansion with the constraints described in
this paper.Comment: Typos corrected, References adde
W Plus Multiple Jets at the LHC with High Energy Jets

We study the production of a W boson in association with n hard QCD jets (for
n>=2), with a particular emphasis on results relevant for the Large Hadron
Collider (7 TeV and 8 TeV). We present predictions for this process from High
Energy Jets, a framework for all-order resummation of the dominant
contributions from wide-angle QCD emissions. We first compare predictions
against recent ATLAS data and then shift focus to observables and regions of
phase space where effects beyond NLO are expected to be large.Comment: 19 pages, 9 figure
Three loop renormalization of 3-quark operators in QCD

We compute the three loop MSbar anomalous dimension for the 3-quark operator
corresponding to the proton. This requires the treatment of gamma^5 within
dimensional regularization as well as evanescent operators generated through
the renormalization. We extend the Larin scheme for gamma^5 to a mixing matrix
of finite renormalization constants chosen so that chiral symmetry is manifest
in four dimensions. We also provide the finite part of the Green's function at
two loops where the operator is inserted at zero momentum in a quark 3-point
function in an arbitrary linear covariant gauge in order to assist with the
lattice measurement of the same quantity. The renormalization of the
generalized 3-quark operators in the scheme devised by Kraenkl and Manashov is
extended to three loops and the anomalous dimensions for the (1/2,0), (3/2,0)
and (1,1/2) spin operators with various chiralities are also given.Comment: 27 latex pages, anc directory now contains txt file with anomalous

Dark matter scenarios in the minimal SUSY B-L model

We perform a study of the dark matter candidates of a constrained version of
the minimal R-parity-conserving supersymmetric model with a gauged
$U(1)_{B-L}$. It turns out that there are four additional candidates for dark
matter in comparison to the MSSM: two kinds of neutralino, which either
correspond to the gaugino of the $U(1)_{B-L}$ or to a fermionic bilepton, as
well as "right-handed" CP-even and -odd sneutrinos. The correct dark matter
relic density of the neutralinos can be obtained due to different mechanisms
including new co-annihilation regions and resonances. The large additional
Yukawa couplings required to break the $U(1)_{B-L}$ radiatively often lead to
large annihilation cross sections for the sneutrinos. The correct treatment of
gauge kinetic mixing is crucial to the success of some scenarios. All
candidates are consistent with the exclusion limits of Xenon100.Comment: 45 pages, 22 figures; v2: extended discussion of direct detection

Localization of Matter Fields in the 5D Standing Wave Braneworld

We investigate the localization problem of matter fields within the 5D
standing wave braneworld. In this model the brane emits anisotropic waves into
the bulk with different amplitudes along different spatial dimensions. We show
that in the case of increasing warp factor there exist the pure gravitational
localization of all kinds of quantum and classical particles on the brane. For
classical particles the anisotropy of the background metric is hidden, brane
fields exhibit standard Lorentz symmetry in spite of anisotropic nature of the
primordial 5D metric.Comment: The version accepted by JHE
Non-Abelian discrete gauge symmetries in 4d string models

We study the realization of non-Abelian discrete gauge symmetries in 4d field
theory and string theory compactifications. The underlying structure
generalizes the Abelian case, and follows from the interplay between gaugings
of non-Abelian isometries of the scalar manifold and field identifications
making axion-like fields periodic. We present several classes of string
constructions realizing non-Abelian discrete gauge symmetries. In particular,
compactifications with torsion homology classes, where non-Abelianity arises
microscopically from the Hanany-Witten effect, or compactifications with
non-Abelian discrete isometry groups, like twisted tori. We finally focus on
the more interesting case of magnetized branes in toroidal compactifications
and quotients thereof (and their heterotic and intersecting duals), in which
the non-Abelian discrete gauge symmetries imply powerful selection rules for
Yukawa couplings of charged matter fields. In particular, in MSSM-like models
they correspond to discrete flavour symmetries constraining the quark and
lepton mass matrices, as we show in specific examples.Comment: 58 pages; minor typos corrected and references adde
Superform formulation for vector-tensor multiplets in conformal
  supergravity

The recent papers arXiv:1110.0971 and arXiv:1201.5431 have provided a
superfield description for vector-tensor multiplets and their Chern-Simons
couplings in 4D N = 2 conformal supergravity. Here we develop a superform
formulation for these theories. Furthermore an alternative means of gauging the
central charge is given, making use of a deformed vector multiplet, which may
be thought of as a variant vector-tensor multiplet. Its Chern-Simons couplings
to additional vector multiplets are also constructed. This multiplet together
with its Chern-Simons couplings are new results not considered by de Wit et al.

Geometric phase outside a Schwarzschild black hole and the Hawking
  effect

We study the Hawking effect in terms of the geometric phase acquired by a
two-level atom as a result of coupling to vacuum fluctuations outside a
Schwarzschild black hole in a gedanken experiment. We treat the atom in
interaction with a bath of fluctuating quantized massless scalar fields as an
open quantum system, whose dynamics is governed by a master equation obtained
by tracing over the field degrees of freedom. The nonunitary effects of this
system are examined by analyzing the geometric phase for the Boulware, Unruh
and Hartle-Hawking vacua respectively. We find, for all the three cases, that
the geometric phase of the atom turns out to be affected by the space-time
curvature which backscatters the vacuum field modes. In both the Unruh and
Hartle-Hawking vacua, the geometric phase exhibits similar behaviors as if
there were thermal radiation at the Hawking temperature from the black hole.
So, a measurement of the change of the geometric phase as opposed to that in a
flat space-time can in principle reveal the existence of the Hawking radiation.Comment: 14 pages, no figures, a typo in the References corrected, version to

Supermembrane origin of type II gauged supergravities in 9D

The M-theory origin of the IIB gauged supergravities in nine dimensions,
classified according to the inequivalent classes of monodromy, is shown to
exactly corresponds to the global description of the supermembrane with central
charges. The global description is a realization of the sculpting mechanism of
gauging (arXiv:1107.3255) and it is associated to particular deformation of
fibrations. The supermembrane with central charges may be formulated in terms
of sections on symplectic torus bundles with SL(2,Z) monodromy. This global
formulation corresponds to the gauging of the abelian subgroups of SL(2,Z)
associated to monodromies acting on the target torus. We show the existence of
the trombone symmetry in the supermembrane formulated as a non-linear
realization of the SL(2,Z) symmetry and construct its gauging in terms of the
supermembrane formulated on an inequivalent class of symplectic torus
fibration. The supermembrane also exhibits invariance under T-duality and we
find the explicit T-duality transformation. It has a natural interpretation in
terms of the cohomology of the base manifold and the homology of the target
torus. We conjecture that this construction also holds for the IIA origin of
gauged supergravities in 9D such that the supermembrane becomes the origin of
all type II supergravities in 9D. The geometric structure of the symplectic
torus bundle goes beyond the classification on conjugated classes of SL(2,Z).
It depends on the elements of the coinvariant group associated to the monodromy
group. The possible values of the (p,q) charges on a given symplectic torus
bundle are restricted to the corresponding equivalence class defining the
element of the coinvariant group.Comment: 41 pages, Latex. Typos corrected, references added, appendix added.

Novel Branches of (0,2) Theories

We show that recently proposed linear sigma models with torsion can be
obtained from unconventional branches of conventional gauge theories. This
observation puts models with log interactions on firm footing. If non-anomalous
multiplets are integrated out, the resulting low-energy theory involves log
interactions of neutral fields. For these cases, we find a sigma model geometry
which is both non-toric and includes brane sources. These are heterotic sigma
models with branes. Surprisingly, there are massive models with compact complex
non-Kahler target spaces, which include brane/anti-brane sources. The simplest
conformal models describe wrapped heterotic NS5-branes. We present examples of
both types.Comment: 36 pages, LaTeX, 2 figures; typo in Appendix fixed; references added

The analysis is based on a data sample of proton-proton collisions collected by the ATLAS experiment at the LHC and corresponding to an integrated luminosity of 4.7fb-1. No significant excess over the expected background is observed in the Higgs boson mass range of 100-150 GeV. The observed (expected) upper limits on the cross section times the branching ratio for H → τ+τ- are found to be between 2.9 (3.4) and 11.7 (8.2) times the Standard Model prediction for this mass rang
