Stringy correlations on deformed $ AdS_{3}\times S^{3} $

In this paper, following the basic prescriptions of Gauge/String duality, we
perform a strong coupling computation on \textit{classical} two point
correlation between \textit{local} (single trace) operators in a gauge theory
dual to $ \kappa $-deformed $ AdS_{3}\times S^{3}$ background. Our construction
is based on the prescription that relates every local operator in a gauge
theory to that with the (semi)classical string states propagating within the
\textit{physical} region surrounded by the holographic screen in deformed $
AdS_3 $. In our analysis, we treat strings as being that of a point like object
located near the physical boundary of the $ \kappa $- deformed Euclidean
Poincare $ AdS_{3} $ and as an extended object with non trivial dynamics
associated to $ S^{3} $. It turns out that in the presence of small background
deformations, the usual power law behavior associated with two point functions
is suppressed exponentially by a non trivial factor which indicates a faster
decay of two point correlations with larger separations. On the other hand, in
the limit of large background deformations ($ \kappa \gg 1 $), the
corresponding two point function reaches a point of saturation. In our
analysis, we also compute finite size corrections associated with these two
point functions at strong coupling. As a consistency check of our analysis, we
find perfect agreement between our results to that with the earlier
observations made in the context of vanishing deformation.Comment: Typos fixed, Published Versio
Quantum Information Metric and Berry Curvature from a Lagrangian
  Approach

We take as a starting point an expression for the quantum geometric tensor
recently derived in the context of the gauge/gravity duality. We proceed to
generalize this formalism in such way it is possible to compute the geometrical
phases of quantum systems. Our scheme provides a conceptually complete
description and introduce a different point of view of earlier works. Using our
formalism, we show how this expression can be applied to well-known quantum
mechanical systems.Comment: 33 pages, references added and minor comment
Renormalization Group Running of Fermion Observables in an Extended
  Non-Supersymmetric SO(10) Model

We investigate the renormalization group evolution of fermion masses, mixings
and quartic scalar Higgs self-couplings in an ${\it extended}$
non-supersymmetric SO(10) model, where the Higgs sector contains the ${\bf
10}_{\rm H}$, ${\bf 120}_{\rm H}$, and ${\bf 126}_{\rm H}$ representations. The
group SO(10) is spontaneously broken at the GUT scale to the Pati-Salam group
and subsequently to the Standard Model (SM) at an intermediate scale $M_{\rm
I}$. We explicitly take into account the effects of the change of gauge groups
in the evolution. In particular, we derive the renormalization group equations
for the different Yukawa couplings. We find that the computed physical fermion
observables can be successfully matched to the experimental measured values at
the electroweak scale. Using the same Yukawa couplings at the GUT scale, the
measured values of the fermion observables cannot be reproduced with a SM-like
evolution, leading to differences in the numerical values up to around 80 %.
Furthermore, a similar evolution can be performed for a ${\it minimal}$ SO(10)
model, where the Higgs sector consists of the ${\bf 10}_{\rm H}$ and ${\bf
126}_{\rm H}$ representations only, showing an equally good potential to
describe the low-energy fermion observables. Finally, for both the extended and
the minimal SO(10) models, we present predictions for the three Dirac and
Majorana CP-violating phases as well as three effective neutrino mass
parameters.Comment: 24 pages, 3 figures, 3 tables. Final version published in JHE
Ubiquity of non-geometry in heterotic compactifications

We study the effect of quantum corrections on heterotic compactifications on
elliptic fibrations away from the stable degeneration limit, elaborating on a
recent observation by Malmendier and Morrison. We show that already for the
simplest non-trivial elliptic fibration the effect is quite dramatic: the $I_1$
degeneration with trivial gauge background dynamically splits into two T-fects
with monodromy around each T-fect being (conjugate to) T-duality along one of
the legs of the $T^2$. This implies that almost every elliptic heterotic
compactification becomes a non-geometric T-fold away from the stable
degeneration limit. We also point out a subtlety due to this non-geometric
splitting at finite fiber size. It arises when determining, via
heterotic/F-theory duality, the SCFTs associated to a small number of pointlike
instantons probing heterotic ADE singularities. Along the way we resolve
various puzzles in the literature.Comment: 23 pages, 4 figure
N=4 super-Yang-Mills in LHC superspace. Part II: Non-chiral correlation
  functions of the stress-tensor multiplet

We study the multipoint super-correlation functions of the full non-chiral
stress-tensor multiplet in N=4 super-Yang-Mills theory in the Born
approximation. We derive effective supergraph Feynman rules for them.
Surprisingly, the Feynman rules for the non-chiral correlators are obtained
from those for the chiral correlators by a simple Grassmann shift of the
space-time variables. We rely on the formulation of the theory in Lorentz
harmonic chiral (LHC) superspace elaborated in the twin paper arXiv:1601.06803.
In this approach only the chiral half of the supersymmetry is manifest. The
other half is realized by nonlinear and nonlocal transformations of the LHC
superfields. However, at Born level only the simple linear part of the
transformations is relevant. It corresponds to effectively working in the
self-dual sector of the theory. Our method is also applicable to a wider class
of supermultiplets like all the half-BPS operators and the Konishi multiplet.Comment: 66 pages, 16 figures; v2: Appendix F on the quantization in a

Scattering of wave packets with phases

A general problem of $2\rightarrow N_f$ scattering is addressed with all the
states being wave packets with arbitrary phases. Depending on these phases, one
deals with coherent states in $(3+1)$ D, vortex particles with orbital angular
momentum, the Airy beams, and their generalizations. A method is developed in
which a number of events represents a functional of the Wigner functions of
such states. Using width of a packet $\sigma_p/\langle p\rangle$ as a small
parameter, the Wigner functions, the number of events, and a cross section are
represented as power series in this parameter, the first non-vanishing
corrections to their plane-wave expressions are derived, and generalizations
for beams are made. Although in this regime the Wigner functions turn out to be
everywhere positive, the cross section develops new specifically quantum
features, inaccessible in the plane-wave approximation. Among them is
dependence on an impact parameter between the beams, on phases of the incoming
states, and on a phase of the scattering amplitude. A model-independent
analysis of these effects is made. Two ways of measuring how a Coulomb phase
and a hadronic one change with a transferred momentum $t$ are discussed.Comment: 37 pages, 6 figures, additional clarifications are mad
Localization on $AdS_2\times S^1$

Conformal symmetry relates the metric on $AdS_2 \times S^{1}$ to that of
$S^3$. This implies that under a suitable choice of boundary conditions for
fields on $AdS_2$ the partition function of conformal field theories on these
spaces must agree which makes $AdS_2 \times S^{1}$ a good testing ground to
study localization on non-compact spaces. We study supersymmetry on
$AdS_2\times S^1$ and determine the localizing Lagrangian for ${\cal N}=2$
supersymmetric Chern-Simons theory on $AdS_2\times S^1$. We evaluate the
partition function of ${\cal N}=2$ supersymmetric Chern-Simons theory on $AdS_2
\times S^1$ using localization, where the radius of $S^1$ is $q$ times that of
$AdS_2$. With boundary conditions on $AdS_2\times S^1$ which ensure that all
the physical fields are normalizable and lie in the space of square integrable
wave functions in $AdS_2$, the result for the partition function precisely
agrees with that of the theory on the $q$-fold covering of $S^3$.Comment: 28 page
QCD analysis of light charged Higgs production through polarized top
  quark decay in two various frames

Light and heavy charged Higgs bosons are predicted by many models with an
extended Higgs sector such as the two-Higgs-doublet model (2HDM). Searches for
the charged Higgs bosons have been done by the ATLAS and the CMS experiments at
the Large Hadron Collider (LHC) in proton-proton collision. However, a
definitive search is a program that still has to be carried out so this belongs
to the LHC experiments. The experimental observation of charged Higgs bosons
would indicate physics beyond the Standard Model. In the present work we study
the ${\cal O}(\alpha_s)$ correction to the energy spectrum of the inclusive
bottom-flavored mesons $(X_b)$ in polarized top quark decays into a light
charged Higgs boson ($m_{H^+}<m_t$) and a massless bottom quark followed by the
hadronization process $b\to X_b$ in the 2HDM, i.e. $t(\uparrow)\to H^+b\to
H^+X_b+Jet$. This spin-dependent energy distribution is studied in two
different helicity coordinate systems. This study could be considered as a new
channel to search for the charged Higgs bosons. To present our phenomenological
predictions, we restrict ourselves to the unexcluded regions of the MSSM
$m_{H^+}-\tan\beta$ parameter space determined by the recent results of the CMS
and the ATLAS collaborations.Comment: arXiv admin note: text overlap with arXiv:1610.0381
Decays of a NMSSM CP-odd Higgs in the low-mass region

A popular regime in the NMSSM parameter space involves a light CP-odd Higgs
$A_1$. This scenario has consequences for e.g. light singlino Dark Matter
annihilating in the $A_1$-funnel. In order to confront the pseudoscalar to
experimental limits such as flavour observables, Upsilon decays or Beam-Dump
experiments, it is necessary to control the interactions of this particle with
hadronic matter and derive the corresponding decays. The partonic description
cannot be relied upon for masses close to $m_{A_1}\sim1$GeV and we employ a
chiral lagrangian, then extended to a spectator model for somewhat larger
masses, to describe the interplay of the CP-odd Higgs with hadrons.
Interestingly, a mixing can develop between $A_1$ and neutral pseudoscalar
mesons, leading to substantial hadronic decays and a coupling of $A_1$ to the
chiral anomaly. Additionally, quartic $A_1$-meson couplings induce tri-meson
decays of the Higgs pseudoscalar. We investigate these effects and propose an
estimate of the Higgs widths for masses below $m_{A_1}\leq3$GeV. While we focus
on the case of the NMSSM, our results are applicable to a large class of
models.Comment: 23 pages, 9 figures, published versio
Inverse Magnetic Catalysis from improved Holographic QCD in the
  Veneziano limit

We study the dependence of the chiral condensate on external magnetic field
in the context of holographic QCD at large number of flavors. We consider a
holographic QCD model where the flavor degrees of freedom fully backreact on
the color dynamics. Perturbative QCD calculations have shown that $B$ acts
constructively on the chiral condensate, a phenomenon called "magnetic
catalysis". In contrast, recent lattice calculations show that, depending on
the number of flavors and temperature, the magnetic field may also act
destructively, which is called "inverse magnetic catalysis". Here we show that
the holographic theory is capable of both behaviors depending on the choice of
parameters. For reasonable choice of the potentials entering the model we find
qualitative agreement with the lattice expectations. Our results provide
insight for the physical reasons behind the inverse magnetic catalysis. In
particular, we argue that the backreaction of the flavors to the background
geometry decatalyzes the condensate.Comment: 22 pages, 8 figure
Couplings in D(2,1;a) superconformal mechanics from the SU(2)
  perspective

Dynamical realizations of the most general N=4 superconformal group in one
dimension D(2,1;a) are reconsidered from the perspective of the R-symmetry
subgroup SU(2). It is shown that any realization of the R-symmetry subalgebra
in some phase space can be extended to a representation of the Lie superalgebra
corresponding to D(2,1;a). Novel couplings of arbitrary number of
supermultiplets of the type (1,4,3) and (0,4,4) with a single supermultiplet of
either the type (3,4,1), or (4,4,0) are constructed. D(2,1;a) superconformal
mechanics describing superparticles propagating near the horizon of the extreme
Reissner-Nordstrom-AdS-dS black hole in four and five dimensions is considered.
The parameter a is linked to the cosmological constant.Comment: V2:15 pages. Lagrangian formulations in Sect. 3, one reference and

Towards New Frontiers in the Exploration of Charmless Non-Leptonic $B$
  Decays

Non-leptonic $B$ decays into charmless final states offer an important
laboratory to study CP violation and the dynamics of strong interactions.
Particularly interesting are $B^0_s\to K^-K^+$ and $B^0_d\to\pi^-\pi^+$ decays,
which are related by the $U$-spin symmetry of strong interactions, and allow
for the extraction of CP-violating phases and tests of the Standard Model. The
theoretical precision is limited by $U$-spin-breaking corrections and
innovative methods are needed in view of the impressive future experimental
precision expected in the era of Belle II and the LHCb upgrade. We have
recently proposed a novel method to determine the $B_s^0$-$\bar{B}_s^0$ mixing
phase $\phi_s$ from the $B_s^0\to K^-K^+$, $B_d^0\to \pi^-\pi^+$ system, where
semileptonic $B^0_s\to K^-\ell^+\nu_\ell$, $B^0_d\to \pi^-\ell^+\nu_\ell$
decays are a new ingredient and the theoretical situation is very favourable.
We discuss this strategy in detail, with a focus on penguin contributions as
well as exchange and penguin-annihilation topologies which can be probed by a
variety of non-leptonic $B$ decays into charmless final states. We show that a
theoretical precision as high as ${\cal O}(0.5^\circ)$ for $\phi_s$ can be
attained in the future, thereby offering unprecedented prospects for the search
for new sources of CP violation.Comment: 50 pages, 25 figure
From Exceptional Field Theory to Heterotic Double Field Theory via K3

In this paper we show how to obtain the heterotic double field theory from
exceptional field theory by breaking half of the supersymmetry. We focus on the
$\mathrm{SL}(5)$ exceptional field theory and show that when the extended space
contains a generalised $\mathrm{SU}(2)$-structure manifold one can define a
reduction to obtain the heterotic $\mathrm{SO}(3,n)$ double field theory. In
this picture, the reduction on the $\mathrm{SU}(2)$-structure breaks half of
the supersymmetry of the exceptional field theory and the gauge group of the
heterotic double field theory is given by the embedding tensor of the reduction
used. Finally, we study the example of a consistent truncation of M-theory on
K3 and recover the duality with the heterotic string on $T^3$. This suggests
that the extended space can be made sense of even in the case of non-toroidal
compactifications.Comment: 23 pages; v2: minor changes, published versio
Dark matter physics, flavor physics and LHC constraints in the dark
  matter model with a bottom partner

In the scenario that a dark matter (DM) is a weakly interacting massive
particle, there are many possibilities of the interactions with the Standard
Model (SM) particles to achieve the relic density of DM. In this paper, we
consider one simple DM model where the DM candidate is a complex scalar and
interacts with the SM particles via exchange of the Higgs particle and an extra
quark, named bottom partner. The extra quark carries the same quantum number as
the right-handed down-type quarks and has Yukawa couplings with the DM
candidate and the right-handed down-type quarks. The Yukawa interactions are
not only relevant to the thermal relic density of the DM, but also contribute
to the flavor physics, such as the $\Delta F=2$ processes. In addition, the
flavor alignment of the Yukawa couplings is related to the decay modes of the
extra quark. Then, we can find the explicit correlations among the physical
observables in DM physics, flavor physics and the signals at the LHC. Based on
the numerical analyses of the thermal relic density, the direct detection of
the DM and the current LHC bounds using the latest results, we survey our
predictions for the $\Delta F=2$ processes. We investigate the perturbative
bound on the Yukawa coupling, as well. Study of a fermionic DM model with extra
scalar quarks is also given for comparison.Comment: 18 pages, 8 figures, 2 tables; some typos corrected, version

Dark matter physics in neutrino specific two Higgs doublet model

Although the seesaw mechanism is a natural explanation for the small neutrino
masses, there are cases when the Majorana mass terms for the right-handed
neutrinos are not allowed due to symmetry. In that case, if neutrino-specific
Higgs doublet is introduced, neutrinos become Dirac particles and their small
masses can be explained by its small VEV. We show that the same symmetry, which
we assume a global $U(1)_X$, can also be used to explain the stability of dark
matter. In our model, a new singlet scalar breaks the global symmetry
spontaneously down to a discrete $Z_2$ symmetry. The dark matter particle,
lightest $Z_2$-odd fermion, is stabilized. We discuss the phenomenology of dark
matter: relic density, direct detection, and indirect detection. We find that
the relic density can be explained by a novel Goldstone boson channel or by
resonance channel. In the most region of parameter space considered, the direct
detections is suppressed well below the current experimental bound. Our model
can be further tested in indirect detection experiments such as FermiLAT gamma
ray searches or neutrinoless double beta decay experiments.Comment: 18 pages, 5 figures, Version accepted by JHE
The $Z$ decay width in the SMEFT: $y_t$ and $\lambda$ corrections at one
  loop

We calculate one loop $y_t$ and $\lambda$ dependent corrections to
$\bar{\Gamma}_Z,\bar{R}_f^0$ and the partial $Z$ widths due to dimension six
operators in the Standard Model Effective Field Theory (SMEFT), including
finite terms. We assume $\rm CP$ symmetry and a $\rm U(3)^5$ symmetry in the UV
matching onto the dimension six operators, dominantly broken by the Standard
Model Yukawa matrices. Corrections to these observables are predicted using the
input parameters $\{\hat{\alpha}_{ew}, \hat{M}_Z, \hat{G}_F, \hat{m}_t,
\hat{m}_h\}$ extracted with one loop corrections in the same limit. We show
that at one loop the number of SMEFT parameters contributing to the precise
LEPI pseudo-observables exceeds the number of measurements. As a result the
SMEFT parameters contributing to LEP data are formally unbounded when the size
of loop corrections are reached until other data is considered in a global
analysis. The size of these loop effects is generically a correction of order
$\sim\%$ to leading effects in the SMEFT, but we find multiple large numerical
coefficients in our calculation at this order. We use a $\rm \overline{MS}$
scheme, modified for the SMEFT, for renormalization. Some subtleties involving
novel evanescent scheme dependence present in this result are explained.Comment: 38 pages + refs, 11 figures, v3: Acknowledgement updated with grant

Leading order multi-soft behaviors of tree amplitudes in NLSM

In this paper, we investigate multi-soft behaviors of tree amplitudes in
nonlinear sigma model (NLSM). The leading behaviors of amplitudes with odd
number of all-adjacent soft pions are zero. We further propose and prove that
leading soft factors of amplitudes with even number all-adjacent soft pions can
be expressed in terms of products of the leading order Berends-Giele
sub-currents in Cayley parametrization. Each sub-current in the expression
contains at most one hard pion. Discussions are generalized to amplitudes
containing arbitrary number of nonadjacent soft blocks: The leading behaviors
of amplitudes where at least one soft block has odd number of adjacent soft
pions are zero; The leading soft factors for amplitudes where all soft blocks
containing even number of soft pions are given by products of soft factors for
these blocks.Comment: 27pages, 7 figures; references added and typos modifie
The Supersymmetric Effective Field Theory of Inflation

We construct the Supersymmetric Effective Field Theory of Inflation, that is
the most general theory of inflationary fluctuations when time-translations and
supersymmetry are spontaneously broken. The non-linear realization of these
invariances allows us to define a complete SUGRA multiplet containing the
graviton, the gravitino, the Goldstone of time translations and the Goldstino,
with no auxiliary fields. Going to a unitary gauge where only the graviton and
the gravitino are present, we write the most general Lagrangian built out of
the fluctuations of these fields, invariant under time-dependent spatial
diffeomorphisms, but softly-breaking time diffeomorphisms and gauged SUSY. With
a suitable St\"uckelberg transformation, we introduce the Goldstone boson of
time translation and the Goldstino of SUSY. No additional dynamical light field
is needed. In the high energy limit, larger than the inflationary Hubble scale
for the Goldstino, these fields decouple from the graviton and the gravitino,
greatly simplifying the analysis in this regime. We study the phenomenology of
this Lagrangian. The Goldstino can have a non-relativistic dispersion relation.
Gravitino and Goldstino affect the primordial curvature perturbations at loop
level. The UV modes running in the loops generate three-point functions which
are degenerate with the ones coming from operators already present in the
absence of supersymmetry. Their size is potentially as large as corresponding
to $f_{\rm NL}^{\rm equil.,\,orthog.}\sim 1$ or, for particular operators, even
$\gg 1$. The non-degenerate contribution from modes of order $H$ is estimated
to be very small.Comment: 55 pages, 2 figure
Lepton-Flavor Violating Mediators

We present a framework where dark matter interacts with the Standard Model
through a light, spin-0 mediator that couples chirally to pairs of
different-flavor leptons. This flavor violating final state weakens bounds on
new physics coupled to leptons from terrestrial experiments and cosmic-ray
measurements. As an example, we apply this framework to construct a model for
the Fermi-LAT excess of GeV $\gamma$-rays from the galactic center. We comment
on the viability of this portal for self-interacting dark matter explanations
of small scale structure anomalies and embeddings in flavor models. Models of
this type are shown to be compatible with the muon anomalous magnetic moment
anomaly. We review current experimental constraints and identify possible
future theoretical and experimental directions.Comment: 27 pages, 7 figures, 1 tabl
Gravitational wave and collider implications of electroweak baryogenesis
  aided by non-standard cosmology

We consider various models realizing baryogenesis during the electroweak
phase transition (EWBG). Our focus is their possible detection in future
collider experiments and possible observation of gravitational waves emitted
during the phase transition. We also discuss the possibility of a non-standard
cosmological history which can facilitate EWBG. We show how acceptable
parameter space can be extended due to such a modification and conclude that
next generation precision experiments such as the ILC will be able to confirm
or falsify many models realizing EWBG. We also show that, in general, collider
searches are a more powerful probe than gravitational wave searches. However,
observation of a deviation from the SM without any hints of gravitational waves
can point to models with modified cosmological history that generically enable
EWBG with weaker phase transition and thus, smaller GW signals
