On neutrino and charged lepton masses and mixings: A view from the
  electroweak-scale right-handed neutrino model

We present a model of neutrino masses within the framework of the EW-$\nu_R$
model in which the experimentally desired form of the PMNS matrix is obtained
by applying an $A_4$ symmetry to the \emph{Higgs singlet sector} responsible
for the neutrino Dirac mass matrix. This mechanism naturally avoids potential
conflict with the LHC data which severely constrains the Higgs sector, in
particular the Higgs doublets. Moreover, by making a simple $ans\ddot{a}tz$ we
extract $\mathcal{M}_l {\mathcal{M}_l}^\dagger$ for the charged lepton sector.
A similar $ans\ddot{a}tz$ is proposed for the quark sector. The sources of
masses for the neutrinos are entirely different from those for the charged
leptons and for the quarks and this might explain why $U_{PMNS}$ is {\em very
different} from $V_{CKM}$.Comment: 19 pages. Two figure
Supersymmetry of IIA warped flux AdS and flat backgrounds

We identify the fractions of supersymmetry preserved by the most general
warped flux AdS and flat backgrounds in both massive and standard IIA
supergravities. We find that $AdS_n\times_w M^{10-n}$ preserve $2^{[{n\over2}]}
k$ for $n\leq 4$ and $2^{[{n\over2}]+1} k$ for $4<n\leq 7$ supersymmetries,
$k\in \bN_{>0}$. In addition we show that, for suitably restricted fields and
$M^{10-n}$, the killing spinors of AdS backgrounds are given in terms of the
zero modes of Dirac like operators on $M^{10-n}$. This generalizes the
Lichnerowicz theorem for connections whose holonomy is included in a general
linear group. We also adapt our results to $\bR^{1,n-1}\times_w M^{10-n}$
backgrounds which underpin flux compactifications to $\bR^{1,n-1}$ and show
that these preserve $2^{[{n\over2}]} k$ for $2<n\leq 4$, $2^{[{n+1\over2}]} k$
for $4<n\leq 8$, and $2^{[{n\over2}]} k$ for $n=9, 10$ supersymmetries.Comment: 44 page
Erratum: Measurement of the inclusive jet cross-section in proton-proton collisions at √s = 7 TeV using 4.5fb −1 of data with the ATLAS detector

Journal of High Energy Physics 2015.9 (2015): 141 reproduced by permission of Scuola Internazionale Superiore di Studi Avanzati (SISSA)It was found that the non-perturbative corrections calculated using Pythia with the Perugia 2011 tune did not include the effect of the underlying event. The affected correction factors were recomputed using the Pythia 6.427 generator. These corrections are applied as baseline to the NLO pQCD calculations and thus the central values of the theoretical predictions have changed by a few percent with the new corrections. This has a minor impact on the agreement between the data and the theoretical predictions. Figures 2 and 6 to 13, and all the tables have been updated with the new values.

F-theory and All Things Rational: Surveying U(1) Symmetries with
  Rational Sections

We study elliptic fibrations for F-theory compactifications realizing 4d and
6d supersymmetric gauge theories with abelian gauge factors. In the fibration
these U(1) symmetries are realized in terms of additional rational sections. We
obtain a universal characterization of all the possible U(1) charges of matter
fields by determining the corresponding codimension two fibers with rational
sections. In view of modelling supersymmetric Grand Unified Theories, one of
the main examples that we analyze are U(1) symmetries for SU(5) gauge theories
with \bar{5} and 10 matter. We use a combination of constraints on the normal
bundle of rational curves in Calabi-Yau three- and four-folds, as well as the
splitting of rational curves in the fibers in codimension two, to determine the
possible configurations of smooth rational sections. This analysis
straightforwardly generalizes to multiple U(1)s. We study the flops of such
fibers, as well as some of the Yukawa couplings in codimension three.
Furthermore, we carry out a universal study of the U(1)-charged GUT singlets,
including their KK-charges, and determine all realizations of singlet fibers.
By giving vacuum expectation values to these singlets, we propose a systematic
way to analyze the Higgsing of U(1)s to discrete gauge symmetries in F-theory.Comment: 93 pages, 23 figure
Magnetoconductivity in chiral Lifshitz hydrodynamics

In this paper, based on the principles of linear response theory, we compute
the longitudinal DC conductivity associated with Lifshitz like fixed points in
the presence of chiral anomalies in ($ 3+1 $) dimensions. In our analysis,
apart from having the usual anomalous contributions due to chiral anomaly, we
observe an additional and pure \textit{parity odd} effect to the
magnetoconductivity which has its origin in the broken Lorentz (boost)
invariance at a Lifshitz fixed point. We also device a holographic set up in
order to compute ($ z=2 $) Lifshitz contributions to the magnetoconductivity
precisely at strong coupling and low charge density limit.Comment: Minor clarifications added, Version To Appear In JHE
Confinement in the q-state Potts model: an RG-TCSA study

In the ferromagnetic phase of the q-state Potts model, switching on an
external magnetic field induces confinement of the domain wall excitations. For
the Ising model (q = 2) the spectrum consists of kink-antikink states which are
the analogues of mesonic states in QCD, while for q = 3, depending on the sign
of the field, the spectrum may also contain three-kink bound states which are
the analogues of the baryons. In recent years the resulting "hadron" spectrum
was described using several different approaches, such as quantum mechanics in
the confining linear potential, WKB methods and also the Bethe-Salpeter
equation. Here we compare the available predictions to numerical results from
renormalization group improved truncated conformal space approach (RG-TCSA).
While mesonic states in the Ising model have already been considered in a
different truncated Hamiltonian approach, this is the first time that a
precision numerical study is performed for the 3-state Potts model. We find
that the semiclassical approach provides a very accurate description for the
mesonic spectrum in all the parameter regime for weak magnetic field, while the
low-energy expansion from the Bethe-Salpeter equation is only valid for very
weak fields where it gives a slight improvement over the semiclassical results.
In addition, we confirm the validity of the recent predictions for the baryon
spectrum obtained from solving the quantum mechanical three-body problem.Comment: 22 pages, pdflatex source with pdf figures. Version 2: references

Majorana Dark Matter in Minimal Higgs Portal Models after LUX

We consider the Singlet Majorana fermion dark matter model, in which the
standard model particles interact with the dark sector through the mixing of a
singlet scalar and the Higgs boson. In this model both the dark matter and the
singlet scalar carry lepton number, the latter being a bilepton. We suppose the
existence of a $Z_2$ symmetry, remnant of some high energy local symmetry
breaking, that stabilizes the Majorana fermion. We analyzed the parameter space
of this model and found that the lepton number symmetry breaking scale, drove
by the singlet scalar, is constrained to be within hundreds to thousands of
GeV, so as to conform with the observed dark matter relic density. Finally, we
address the direct detection and invisible Higgs decay complementarity,
confronting our model with recent LUX and LHC constraints, as well as XENON1T
prospects.Comment: 20 pages, 12 figure
The Anomalous Scaling Exponents of Turbulence in General Dimension from
  Random Geometry

We propose an exact analytical formula for the anomalous scaling exponents of
inertial range structure functions in incompressible fluid turbulence. The
formula is a gravitational Knizhnik-Polyakov-Zamolodchikov (KPZ)-type relation,
and is valid in any number of space dimensions. It incorporates intermittency
by gravitationally dressing the Kolmogorov linear scaling via a coupling to a
random geometry. The formula has one real parameter $\gamma$ that depends on
the number of space dimensions. The scaling exponents satisfy the convexity
inequality, and the supersonic bound constraint. They agree with the
experimental and numerical data in two and three space dimensions, and with
numerical data in four space dimensions. Intermittency increases with $\gamma$,
and in the infinite $\gamma$ limit the scaling exponents approach the value
one, as in Burgers turbulence. At large $n$ the $n$th order exponent scales as
$\sqrt{n}$. We discuss the relation between fluid flows and black hole geometry
that inspired our proposal.Comment: 18 pages, 3 figures; v3: additional clarifications, added references;

Probing U(1) extensions of the MSSM at the LHC Run I and in dark matter
  searches

The U(1) extended supersymmetric standard model (UMSSM) can accommodate a
Higgs boson at 125 GeV without relying on large corrections from the top/stop
sector. After imposing LHC results on the Higgs sector, on B-physics and on new
particle searches as well as dark matter constraints, we show that this model
offers two viable dark matter candidates, the right-handed (RH) sneutrino or
the neutralino. Limits on supersymmetric partners from LHC simplified model
searches are imposed using SModelS and allow for light squarks and gluinos.
Moreover the upper limit on the relic abundance often favours scenarios with
long-lived particles. Searches for a Z' at the LHC remain the most unambiguous
probes of this model. Interestingly, the D-term contributions to the sfermion
masses allow to explain the anomalous magnetic moment of the muon in specific
corners of the parameter space with light smuons or left-handed (LH)
sneutrinos. We finally emphasize the interplay between direct searches for dark
matter and LHC simplified model searches.Comment: 55 pages, 29 figures; v2: references added; v3: clarifications,

Standard Model Effective Field Theory: Integrating out a Generic Scalar

We consider renormalisable models extended in the scalar sector by a generic
scalar field in addition to the standard model Higgs boson field, and work out
the effective theory for the latter in the decoupling limit. We match the full
theory onto the effective theory at tree and one-loop levels, and concentrate
on dimension-6 operators of the Higgs and electroweak gauge fields induced from
such matching. The Wilson coefficients of these dimension-6 operators from
tree-level matching are further improved by renormalisation group running. For
specific $SU(2)_L$ representations of the scalar field, some "accidental"
couplings with the Higgs field are allowed and can lead to dimension-6
operators at tree and/or one-loop level. Otherwise, two types of interaction
terms are identified to have only one-loop contributions, for the Wilson
coefficients of which we have obtained a general formula. Using the obtained
results, we analyse constraints from electroweak oblique parameters and the
Higgs data on several phenomenological models.Comment: corrections on RGE improvemen
Abelian 3d mirror symmetry on $\mathbb{RP}^2 \times \mathbb{S}^1$ with
  $N_f=1$

We consider a new 3d superconformal index defined as the path integral over
$\mathbb{RP}^2 \times \mathbb{S}^1$, and get the generic formula for this index
with arbitrary number of U$(1)$ gauge symmetries via the localization
technique. We find two consistent parity conditions for the vector multiplet,
and name them $\mathcal{P}$ and $\mathcal{CP}$. We find an interesting
phenomenon that two matter multiplets coupled to the $\mathcal{CP}$-type vector
multiplet merge together. By using this effect, we investigate the simplest
version of 3d mirror symmetry on $\mathbb{RP}^2 \times \mathbb{S}^1$ and
observe four types of coincidence between the SQED and the XYZ model. We find
that merging two matters plays an important role for the agreement.Comment: 28 pages, formulas modified and comments adde
Mass-Splitting between Haves and Have-Nots (Symmetry vs. Grand Unified
  Theory)

We revisit the long-standing problem of supersymmetric grand unified theory
(GUT), the doublet-triplet splitting problem. We discuss whether symmetry which
controls the {\mu} term in the minimal supersymmetric standard model is
compatible with GUT. We find that the symmetry must be broken at the GUT scale.
A similar argument also shows that the R symmetry, which is important for low
energy supersymmetry, must be broken down to a Z2R symmetry at the GUT scale.
We propose a new prescription to achieve the doublet-triplet splitting by
symmetry. There, the symmetry which controls the {\mu} term is spontaneously
broken at the GUT scale by order parameters which are charged under other
symmetries. Bilinear terms of triplet Higgses are charged under the other
symmetries, while those of doublet Higgses are not. Then triplet Higgses
directly couple to the order parameters and hence obtain GUT scale masses,
while doublet Higgses obtain suppressed masses. The broken R symmetry can be
also effectively preserved by a similar prescription. As a demonstration, we
construct an SU(5)$\times$SU(5) GUT model. We also comment on unification of
yukawa couplings.Comment: 25 pages, 4 figure
Sneutrino Higgs models explain lepton non-universality in CMS excesses

Recent searches for first-generation leptoquarks and heavy right-handed $W_R$
bosons have seen excesses in final states with electrons and jets. A bizarre
property of these excesses is that they appear to violate lepton universality.
With these results in mind, we study the phenomenology of supersymmetric models
in which the Higgs arises as the sneutrino in an electron supermultiplet. Since
the electron is singled out in this approach, one can naturally account for the
lepton flavor structure of the excesses. In this work, we show that in such a
framework, one can significantly alleviate the tension between the Standard
Model and the data and yet evade current constraints from other searches.
Lastly we point out that correlated excesses are expected to be seen in future
multilepton searches.Comment: 17 pages, 7 figure
Resurgence in sine-Gordon quantum mechanics: Exact agreement between
  multi-instantons and uniform WKB

We compute multi-instanton amplitudes in the sine-Gordon quantum mechanics
(periodic cosine potential) by integrating out quasi-moduli parameters
corresponding to separations of instantons and anti-instantons. We propose an
extension of Bogomolnyi--Zinn-Justin prescription for multi-instanton
configurations and an appropriate subtraction scheme. We obtain the
multi-instanton contributions to the energy eigenvalue of the lowest band at
the zeroth order of the coupling constant. For the configurations with only
instantons (anti-instantons), we obtain unambiguous results. For those with
both instantons and anti-instantons, we obtain results with imaginary parts,
which depend on the path of analytic continuation. We show that the imaginary
parts of the multi-instanton amplitudes precisely cancel the imaginary parts of
the Borel resummation of the perturbation series, and verify that our results
completely agree with those based on the uniform-WKB calculations, thus
confirming the resurgence : divergent perturbation series combined with the
nonperturbative multi-instanton contributions conspire to give unambiguous
results. We also study the neutral bion contributions in the ${\mathbb
C}P^{N-1}$ model on ${\mathbb R}^1\times S^{1}$ with a small circumference,
taking account of the relative phase moduli between the fractional instanton
and anti-instanton. We find that the sign of the interaction potential depends
on the relative phase moduli, and that both the real and imaginary parts
resulting from quasi-moduli integral of the neutral bion get quantitative
corrections compared to the sine-Gordon quantum mechanics.Comment: 44 pages, 13 figures, typos corrected, references update
Improved prediction for the mass of the W boson in the NMSSM

Electroweak precision observables, being highly sensitive to loop
contributions of new physics, provide a powerful tool to test the theory and to
discriminate between different models of the underlying physics. In that
context, the $W$ boson mass, $M_W$, plays a crucial role. The accuracy of the
$M_W$ measurement has been significantly improved over the last years, and
further improvement of the experimental accuracy is expected from future LHC
measurements. In order to fully exploit the precise experimental determination,
an accurate theoretical prediction for $M_W$ in the Standard Model (SM) and
extensions of it is of central importance. We present the currently most
accurate prediction for the $W$ boson mass in the Next-to-Minimal
Supersymmetric extension of the Standard Model (NMSSM), including the full
one-loop result and all available higher-order corrections of SM and SUSY type.
The evaluation of $M_W$ is performed in a flexible framework, which facilitates
the extension to other models beyond the SM. We show numerical results for the
$W$ boson mass in the NMSSM, focussing on phenomenologically interesting
scenarios, in which the Higgs signal can be interpreted as the lightest or
second lightest CP-even Higgs boson of the NMSSM. We find that, for both Higgs
signal interpretations, the NMSSM $M_W$ prediction is well compatible with the
measurement. We study the SUSY contributions to $M_W$ in detail and investigate
in particular the genuine NMSSM effects from the Higgs and neutralino sectors.Comment: 43 pages, 21 figure
Five-Dimensional Gauge-Higgs Unification: A Standard Model-Like Spectrum

We study the viability of five-dimensional gauge theories as candidates for
the origin of the Higgs field and its mechanism for spontaneous symmetry
breaking. Within the framework of lattice field theory, we consider the
simplest model of an $SU(2)$ gauge theory. We construct this theory on a
five-dimensional orbifold which explicitly breaks the gauge symmetry to $U(1)$
at the fixed points of the orbifold. Using anisotropic gauge couplings, we find
that this theory exhibits three distinct phases which we label as confined,
Higgs and hybrid. Within the Higgs phase, close to the Higgs-hybrid phase
transition, we find that the ratio of the Higgs to gauge boson masses takes
Standard Model-like values. Precisely in this region of the phase diagram, we
find dimensional reduction via localisation.Comment: Version accepted for publication in JHEP. 36 pages, 13 figure
Emergent scale invariance of disordered horizons

We construct planar black hole solutions in AdS_3 and AdS_4 in which the
boundary CFT is perturbed by marginally relevant quenched disorder. We show
that the entropy density of the horizon has the scaling temperature dependence
s \sim T^{(d-1)/z} (with d=2,3). The dynamical critical exponent z is computed
numerically and, at weak disorder, analytically. These results lend support to
the claim that the perturbed CFT flows to a disordered quantum critical theory
in the IR.Comment: 1+22 pages. 4 figure
A stable Higgs portal with vector dark matter

We explore an extension of the Standard Model by an additional U (1) gauge
group and a complex scalar Higgs portal. As the scalar is charged under this
gauge factor this simple model supplies a vector dark matter candidate
satisfying the observed relic abundance and limits from direct dark matter
searches. An additional Higgs-like state, that may be heavier or lighter than
the observed Higgs, is present and satisfies LEP and LHC bounds whilst allowing
for absolute stability of the electroweak vacuum in a range of parameter space.Comment: 32 pages, 18 figures, v2: references added, minor corrections,

AdS5 solutions from M5-branes on Riemann surface and D6-branes sources

We describe the gravity duals of four-dimensional N=1 superconformal field
theories obtained by wrapping M5-branes on a punctured Riemann surface. The
internal geometry, normal to the AdS5 factor, generically preserves two U(1)s,
with generators (J+,J-), that are fibered over the Riemann surface. The metric
is governed by a single potential that satisfies a version of the Monge-Ampere
equation. The spectrum of N=1 punctures is given by the set of supersymmetric
sources of the potential that are localized on the Riemann surface and lead to
regular metrics near a puncture. We use this system to study a class of
punctures where the geometry near the sources corresponds to M-theory
description of D6-branes. These carry a natural (p,q) label associated to the
circle dual to the killing vector (p J+ + q J-) which shrinks near the source.
In the generic case the world volume of the D6-branes is AdS5 X S^2 and they
locally preserve N=2 supersymmetry. When p=-q, the shrinking circle is dual to
a flavor U(1). The metric in this case is non-degenerate only when there are
co-dimension one sources, M9-branes, obtained by smearing M5-branes that wrap
the AdS5 factor and the circle dual the superconformal R-symmetry. In the IIA
limit, they can interpreted as D8-branes. The D6-branes are extended along the
AdS5 and on cups that end on the co-dimension one branes. In the special case
when the shrinking circle is dual to the R-symmetry, the D6-branes are extended
along the AdS5 and wrap an auxiliary Riemann surface with an arbitrary genus.
When the Riemann surface is compact with constant curvature, the system is
governed by a Monge-Ampere equation.Comment: 35 page
On the Time Evolution of Holographic n-partite Information

We study various scaling behaviors of n-partite information during a process
of thermalization after a global quantum quench for n disjoint system
consisting of n parallel strips whose widths are much larger than the
separation between them. By making use of the holographic description for
entanglement entropy we explore holographic description of the n-partite
information by which we show that it has a definite sign: it is positive for
even n and negative for odd n. This might be thought of as an intrinsic
property of a field theory which has gravity dual.Comment: 48 pages, 29 figures; v2: Reference added; v3: Few comments and

Factorization for radiative heavy quarkonium decays into scalar Glueball

We establish the factorization formula for scalar Glueball production through
radiative decays of vector states of heavy quarkonia, e.g. $J/\psi$, $\psi(2S)$
and $\Upsilon(nS)$, where the Glueball mass is much less than the parent heavy
quarkonium mass. The factorization is demonstrated explicitly at one-loop level
through the next-to-leading order (NLO) corrections to the hard kernel, the
non-relativistic QCD (NRQCD) long-distance matrix element (LDMEs) of the heavy
quarkonium, and the light-cone distribution amplitude (LCDA) of scalar
Glueball. The factorization provides a comprehensive theoretical approach to
investigate Glueball production in the radiative decays of vector states of
heavy quarkonia and to determine the physic nature of Glueball. We discuss the
scale evolution equation of LCDA for scalar Glueball. In the end, we extract
the value of the decay constant of Scalar Glueball from Lattice QCD calculation
and analyze the mixing effect among $f_0(1370)$, $f_0(1500)$ and $f_0(1710)$.Comment: 15 pages, 3 figures, and 1 table; version to appear in JHE
