The Holographic Dictionary for Beta Functions of Multi-trace Coupling
  Constants

Field theories with weakly coupled holographic duals, such as large N gauge
theories, have a natural separation of their operators into `single-trace
operators' (dual to single-particle states) and `multi-trace operators' (dual
to multi-particle states). There are examples of large N gauge theories where
the beta functions of single-trace coupling constants all vanish, but marginal
multi-trace coupling constants have non-vanishing beta functions that spoil
conformal invariance (even when all multi-trace coupling constants vanish). The
holographic dual of such theories should be a classical solution in anti-de
Sitter space, in which the boundary conditions that correspond to the
multi-trace coupling constants depend on the cutoff scale, in a way that spoils
conformal invariance. We argue that this is realized through specific bulk
coupling constants that lead to a running of the multi-trace coupling
constants. This fills a missing entry in the holographic dictionary.Comment: 31 pages. v2: added references. v3: added references, JHEP versio
Bulk emergence and the RG flow of entanglement entropy

We further develop perturbative methods used to calculate entanglement entropy (EE) away from an interacting CFT fixed point. At second order we find certain universal terms in the renormalized EE which were predicted previously from holography and which we find hold universally for relevant deformations of any CFT in any dimension. We use both replica methods and direct methods to calculate the EE and in both cases find a non-local integral expression involving the CFT two point function. We show that this integral expression can be written as a local integral over a higher dimensional bulk modular hamiltonian in an emergent AdS space-time. This bulk modular hamiltonian is associated to an emergent scalar field dual to the deforming operator. We generalize to arbitrary spatially dependent couplings where a linearized metric emerges naturally as a way of efficiently encoding the field theory entanglement: by demanding that Einstein’s equations coupled to the bulk scalar field are satisfied, we show that EE can be calculated as the area of this metric. Not only does this show a direct emergence of a higher dimensional gravitational theory from any CFT, it allows for effective evaluation of the the integrals required to calculate EE perturbativly. Our results can also be interpreted as relating the non-locality of the modular hamiltonian for a spherical region in non-CFTs and the non-locality of the holographic bulk to boundary map
Hunting electroweakinos at future hadron colliders and direct detection experiments

We analyse the mass reach for electroweakinos at future hadron colliders and their interplay with direct detection experiments. Motivated by the LHC data, we focus on split supersymmetry models with different electroweakino spectra. We find for example that a 100 TeV collider may explore Winos up to ∼ 7 TeV in low scale gauge mediation models or thermal Wino dark matter around 3 TeV in models of anomaly mediation with long-lived Winos. We show moreover how collider searches and direct detection experiments have the potential to cover large part of the parameter space even in scenarios where the lightest neutralino does not contribute to the whole dark matter relic density
A light pseudoscalar of 2HDM confronted with muon g-2 and experimental constraints

A light pseudoscalar of the lepton-specific 2HDM can enhance the muon g-2, but suffer from various constraints easily, such as the 125.5 GeV Higgs signals, non-observation of additional Higgs at the collider and even B s → μ + μ − . In this paper, we take the light CP-even Higgs as the 125.5 GeV Higgs, and examine the implications of those observables on a pseudoscalar with the mass below the half of 125.5 GeV. Also the other relevant theoretical and experimental constraints are considered. We find that the pseudoscalar can be allowed to be as low as 10 GeV, but the corresponding tan β , sin( β − α ) and the mass of charged Higgs are strongly constrained. In addition, the surviving samples favor the wrong-sign Yukawa coupling region, namely that the 125.5 GeV Higgs couplings to leptons have opposite sign to the couplings to gauge bosons and quarks
Improving the sensitivity of stop searches with on-shell constrained invariant mass variables

The search for light stops is of paramount importance, both in general as a promising path to the discovery of beyond the standard model physics and more specifically as a way of evaluating the success of the naturalness paradigm. While the LHC experiments have ruled out much of the relevant parameter space, there are “stop gaps”, i.e., values of sparticle masses for which existing LHC analyses have relatively little sensitivity to light stops. We point out that techniques involving on-shell constrained M 2 variables can do much to enhance sensitivity in this region and hence help close the stop gaps. We demonstrate the use of these variables for several benchmark points and describe the effect of realistic complications, such as detector effects and combinatorial backgrounds, in order to provide a useful toolkit for light stop searches in particular, and new physics searches at the LHC in general
Covariant Noether Charge for Higher Dimensional Chern-Simons Terms

We construct a manifestly covariant differential Noether charge for theories
with Chern-Simons terms in higher dimensional spacetimes. This is in contrast
to Tachikawa's extension of the standard Lee-Iyer-Wald formalism which results
in a non-covariant differential Noether charge for Chern-Simons terms. On a
bifurcation surface, our differential Noether charge integrates to the
Wald-like entropy formula proposed by Tachikawa in arXiv:hep-th/0611141.Comment: 45 pages; v2: minor corrections and JHEP versio
RG domain wall for the N=1 minimal superconformal models

We specify Gaiotto’s proposal for the RG domain wall between some coset CFT models to the case of two minimal N=1 SCFT models SM p and SM p −2 related by the RG flow initiated by the top component of the Neveu-Schwarz superfield Φ 1,3 . We explicitly calculate the mixing coefficients for several classes of fields and compare the results with the already known in literature results obtained through perturbative analysis. Our results exactly match with both leading and next to leading order perturbative calculations
Lepton flavour violating signature in supersymmetric U(1) ′ seesaw models at the LHC

We consider a U(1) ′ supersymmetric seesaw model in which a right-handed sneutrino is a thermal dark matter candidate whose relic density can be in the right range due to its coupling to relatively light Z ˜ ′ $$ \tilde{Z}^{\prime } $$ , the superpartner of the extra gauge boson Z ′ . Such light Z ˜ ′ $$ \tilde{Z}^{\prime } $$ can be produced at the LHC through cascade decays of colored superparticles, in particular, stops and sbottoms, and then decay to a right-handed neutrino and a sneutrino dark matter, which leads to lepton flavor violating signals of same/opposite-sign dileptons (or multileptons) accompanied by large missing energy. Taking some benchmark points, we analyze the opposite- and same-sign dilepton signatures and the corresponding flavour difference i.e., (2 e − 2 μ ). It is shown that 5 σ signal significance can be reached for some benchmark points with very early data of ∼ 2 fb −1 integrated luminosity. In addition, 3 ℓ and 4 ℓ signatures also look promising to check the consistency in the model prediction, and it is possible to reconstruct the Z ˜ ′ $$ \tilde{Z}^{\prime } $$ mass from jjℓ invariant mass distribution
The Superconformal Index of the (2,0) Theory with Defects

We compute the supersymmetric partition function of the six-dimensional (2,0) theory of type AN−1 on S1×S5 in the presence of both codimension two and codimension four defects. We concentrate on a limit of the partition function depending on a single parameter. From the allowed supersymmetric configurations of defects we find a precise match with the characters of irreducible modules of WN algebras and affine Lie algebras of type AN−1.We compute the supersymmetric partition function of the six-dimensional (2,0) theory of type AN−1 on S1×S5 in the presence of both codimension two and codimension four defects.

Superforms in five-dimensional, N = 1 superspace

We examine the five-dimensional super-de Rham complex with N = 1 super-symmetry. The elements of this complex are presented explicitly and related to those of the six-dimensional complex in N = (1 , 0) superspace through a specific notion of dimensional reduction. This reduction also gives rise to a second source of five-dimensional super-cocycles that is based on the relative cohomology of the two superspaces. In the process of investigating these complexes, we discover various new features including branching and fusion (loops) in the super-de Rham complex, a natural interpretation of “Weil triviality”, p -cocycles that are not supersymmetric versions of closed bosonic p -forms, and the opening of a “gap” in the complex for D > 4 in which we find a multiplet of superconformal gauge parameters
CHY representations for gauge theory and gravity amplitudes with up to
  three massive particles

We show that a wide class of tree-level scattering amplitudes involving
scalars, gauge bosons, and gravitons, up to three of which may be massive, can
be expressed in terms of a Cachazo-He-Yuan representation as a sum over
solutions of the scattering equations. These amplitudes, when expressed in
terms of the appropriate kinematic invariants, are independent of the masses
and therefore identical to the corresponding massless amplitudes.Comment: 20 pages, 1 figure; v2: minor typos corrected, published versio
Non-extremal black hole solutions from the c-map

We construct new static, spherically symmetric non-extremal black hole
solutions of four-dimensional ${\cal N}=2$ supergravity, using a systematic
technique based on dimensional reduction over time (the c-map) and the real
formulation of special geometry. For a certain class of models we actually
obtain the general solution to the full second order equations of motion,
whilst for other classes of models, such as those obtainable by dimensional
reduction from five dimensions, heterotic tree-level models, and type-II
Calabi-Yau compactifications in the large volume limit a partial set of
solutions are found. When considering specifically non-extremal black hole
solutions we find that regularity conditions reduce the number of integration
constants by one half. Such solutions satisfy a unique set of first order
equations, which we identify.
  Several models are investigated in detail, including examples of
non-homogeneous spaces such as the quantum deformed $STU$ model. Though we
focus on static, spherically symmetric solutions of ungauged supergravity, the
method is adaptable to other types of solutions and to gauged supergravity.Comment: 57 pages. Minor changes to the introduction, typos corrected and

Diffractive dijet production with a leading proton in ep collisions at HERA

The cross section of the diffractive process e + p → e + Xp is measured at a centre-of-mass energy of 318 GeV, where the system X contains at least two jets and the leading final state proton p is detected in the H1 Very Forward Proton Spectrometer. The measurement is performed in photoproduction with photon virtualities Q 2 < 2 GeV 2 and in deep-inelastic scattering with 4 GeV 2 < Q 2 < 80 GeV 2 . The results are compared to next- to-leading order QCD calculations based on diffractive parton distribution functions as extracted from measurements of inclusive cross sections in diffractive deep-inelastic scattering
$\overline{\rm D3}$ and dS

The role of the $\overline{\rm D3}$ brane in providing de Sitter vacua with
spontaneously broken supersymmetry in the KKLT construction is clarified. The
first step in this direction was explained in arXiv:hep-th/0301240,
arXiv:hep-th/0308055: it was shown there that in the GKP background the bosonic
contributions to the vacuum energy from the DBI and WZ term cancel for a D3
brane, but double for a $\overline{\rm D3}$ brane, leading to de Sitter vacua.
The next step was taken in arXiv:1411.1121 where the analogous mechanism of the
doubling (cancelation) of the $\overline{\rm D3}$ (D3) DBI and WZ terms was
discovered in the presence of Volkov-Akulov fermions living on the brane, in a
flat supergravity background. Here we confirm this mechanism of
doubling/cancelation for the $\overline{\rm D3}$/D3 brane in the GKP
supergravity background preserving $\mathcal{N}=1$, $d=4$ supersymmetry. We
find that imaginary self-dual $G_{(3)}$ flux of type $(2,1)$ nicely removes the
$SU(3)$ fermion triplet by giving it a large mass, while leaving the
Volkov-Akulov goldstino, which is the $SU(3)$ singlet, massless. This makes the
de Sitter landscape in D-brane physics clearly related to de Sitter vacua in
effective $d=4$ supergravity with a nilpotent multiplet and spontaneously
broken supersymmetry.Comment: 25 pages; v2: added clarifying comments and one referenc
Peccei-Quinn invariant singlet extended SUSY with anomalous U(1) gauge symmetry

Recent discovery of the SM-like Higgs boson with m h ≃ 125 GeV motivates an extension of the minimal supersymmetric standard model (MSSM), which involves a singlet Higgs superfield with a sizable Yukawa coupling to the doublet Higgs superfields. We examine such singlet-extended SUSY models with a Peccei-Quinn (PQ) symmetry that originates from an anomalous U(1) A gauge symmetry. We focus on the specific scheme that the PQ symmetry is spontaneously broken at an intermediate scale v PQ  ∼  m SUSY M Pl by an interplay between Planck scale suppressed operators and tachyonic soft scalar mass m SUSY ∼ D A $$ {m}_{\mathrm{SUSY}}\sim \sqrt{D_A} $$ induced dominantly by the U(1) A D -term D A . This scheme also results in spontaneous SUSY breaking in the PQ sector, generating the gaugino masses m 1 / 2 ∼ D A $$ {m}_{1/2}\sim \sqrt{D_A} $$ when it is transmitted to the MSSM sector by the conventional gauge mediation mechanism. As a result, the MSSM soft parameters in this scheme are induced mostly by the U(1) A D -term and the gauge mediated SUSY breaking from the PQ sector, so that the sparticle masses can be near the present experimental bounds without causing the SUSY flavor problem. The scheme is severely constrained by the condition that a phenomenologically viable form of the low energy operators of the singlet and doublet Higgs superfields is generated by the PQ breaking sector in a way similar to the Kim-Nilles solution of the μ problem, and the resulting Higgs mass parameters allow the electroweak symmetry breaking with small tan β . We find two minimal models with two singlet Higgs superfields, satisfying this condition with a relatively simple form of the PQ breaking sector, and briefly discuss some phenomenological aspects of the model
ABJM Theory with mass and FI deformations and Quantum Phase Transitions

The phase structure of ABJM theory with mass $m$ deformation and
non-vanishing Fayet-Iliopoulos (FI) parameter, $\zeta$, is studied through the
use of localisation on ${\mathbb S}^3$. The partition function of the theory
then reduces to a matrix integral, which, in the large $N$ limit and at large
sphere radius, is exactly computed by a saddle-point approximation. When the
couplings are analytically continued to real values, the phase diagram of the
model becomes immensely rich, with an infinite series of third-order phase
transitions at vanishing FI-parameter. As the FI term is introduced, new
effects appear. For any given $0 < \zeta < m/2$, the number of phases is finite
and for $\zeta\geq m/2$ the theory does not have any phase transitions at all.
  Finally, we argue that ABJM theory with physical couplings does not undergo
phase transitions and investigate the case of $U(2)\times U(2)$ gauge group in
detail by an explicit calculation of the partition function.Comment: 42 pages, 7 figures. Minor revisions of eq. (19) and section 6.2.2 to

Non-thermal fixed point in a holographic superfluid

We study the far-from-equilibrium dynamics of a (2 + 1)-dimensional super-fluid at finite temperature and chemical potential using its holographic description in terms of a gravitational system in 3 + 1 dimensions. Starting from various initial conditions corresponding to ensembles of vortex defects we numerically evolve the system to long times. At intermediate times the system exhibits Kolmogorov scaling the emergence of which depends on the choice of initial conditions. We further observe a universal late- time regime in which the occupation spectrum and different length scales of the superfluid exhibit scaling behaviour. We study these scaling laws in view of superfluid turbulence and interpret the universal late-time regime as a non-thermal fixed point of the dynamical evolution. In the holographic superfluid the non-thermal fixed point can be understood as a stationary point of the classical equations of motion of the dual gravitational description
Improved lattice fermion action for heavy quarks

We develop an improved lattice action for heavy quarks based on
Brillouin-type fermions, that have excellent energy-momentum dispersion
relation. The leading discretization errors of $O(a)$ and $O(a^2)$ are
eliminated at tree-level. We carry out a scaling study of this improved
Brillouin fermion action on quenched lattices by calculating the charmonium
energy-momentum dispersion relation and hyperfine splitting. We present a
comparison to standard Wilson fermions and domain-wall fermions.Comment: 33 pages, 23 figures, minor changes are made, a version published in

Model-independent calculation of $SU(3)_f$ violation in baryon octet
  light-cone distribution amplitudes

In this work we present a minimal parametrization of the light-cone
distribution amplitudes of the baryon octet including higher twist
contributions. Simultaneously we obtain the quark mass dependence of the
amplitudes at leading one-loop accuracy by the use of three-flavor baryon
chiral perturbation theory (BChPT), which automatically yields
model-independent results for the leading $SU(3)$ flavor breaking effects. For
that purpose we have constructed the nonlocal light-cone three-quark operators
in terms of baryon octet and meson fields and have carried out a
next-to-leading order BChPT calculation. We were able to find a minimal set of
distribution amplitudes (DAs) that do not mix under chiral extrapolation
towards the physical point and naturally embed the $\Lambda$ baryon.
Additionally they are chosen in such a way that all DAs of a certain symmetry
class have a similar quark mass dependence (independent of the twist of the
corresponding amplitude), which allows for a compact presentation. The results
are well-suited for the extrapolation of lattice data and for model building.Comment: We have updated the text to match the version published in JHE
Phase Transitions in Warped AdS$_3$ Gravity

We consider asymptotically Warped AdS$_3$ black holes in Topologically
Massive Gravity. We study their thermodynamic stability and show the existence
of a Hawking-Page phase transition between the black hole and thermal
background phases. At zero angular potential, the latter is shown to occur at
the self-dual point of the dual Warped Conformal Field Theory partition
function, in analogy with the phase transition for BTZ black holes in
AdS$_3$/CFT$_2$. We also discuss how the central and vacuum charges can be
obtained from inner horizon mechanics in the presence of a gravitational
anomaly.Comment: 30 pages, 6 figure
On the Central Charge of Spacetime Current Algebras and Correlators in
  String Theory on AdS3

Spacetime Virasoro and affine Lie algebras for strings propagating in AdS3
are known to all orders in $\alpha'$. The central extension of such algebras is
a string vertex, whose expectation value can depend on the number of long
strings present in the background but should be otherwise state-independent. In
hep-th/0106004, on the other hand, a state-dependent expectation value was
found. Another puzzling feature of the theory is lack of cluster decomposition
property in certain connected correlators. This note shows that both problems
can be removed by defining the free energy of the spacetime boundary conformal
field theory as the Legendre transform of the formula proposed in the
literature. This corresponds to pass from a canonical ensemble, where the
number of fundamental strings that create the background can fluctuate, to a
microcanonical one, where it is fixed.Comment: 10 pages, one minor correction, version published in JHE
Probing texture zeros with scaling ansatz in inverse seesaw

We investigate neutrino mass matrix phenomenology involving scaling ansatz
and texture zeros adhering inverse seesaw mechanism. It is seen that four is
the maximum number of zeros in $m_D$ and $\mu$ to obtain viable phenomenology.
Depending upon the generic nature of the effective neutrino mass matrices we
classify all the emerged matrices in four categories. One of them is ruled out
phenomenologically due to inappropriate value of reactor mixing angle after
breaking of the scaling ansatz. The mass ordering is inverted in all cases. One
of the distinguishable feature of all these categories is the vanishingly small
value of CP violation measure $J_{CP}$ due to small value of $\delta_{CP}$.
Thus those categories will be ruled out if CP violation is observed in the
leptonic sector in future experiments.Comment: 23 pages, 9 figures, Published versio
Nernst branes from special geometry

We construct new black brane solutions in $U(1)$ gauged ${\cal N}=2$
supergravity with a general cubic prepotential, which have entropy density
$s\sim T^{1/3}$ as $T \rightarrow 0$ and thus satisfy the Nernst Law. By using
the real formulation of special geometry, we are able to obtain analytical
solutions in closed form as functions of two parameters, the temperature $T$
and the chemical potential $\mu$. Our solutions interpolate between
hyperscaling violating Lifshitz geometries with $(z,\theta)=(0,2)$ at the
horizon and $(z,\theta)=(1,-1)$ at infinity. In the zero temperature limit,
where the entropy density goes to zero, we recover the extremal Nernst branes
of Barisch et al, and the parameters of the near horizon geometry change to
$(z,\theta)=(3,1)$.Comment: 37 pages. v2: numerical pre-factors of scalar fields q_A corrected in
