Quark-Lepton Complementarity Predictions for $\theta_{23}^{pmns}$ and CP
  Violation

In the light of recent experimental results on $\theta_{13}^{pmns}$, we
re-investigate the complementarity between the quark and lepton mixing matrices
and obtain predictions for most unsettled neutrino mixing parameters like
$\theta_{23}^{pmns}$ and CP violating phase invariants $J$, $S_1$ and $S_2$.
This paper is motivated by our previous work where in a QLC model we predicted
the value for $\theta_{13}^{pmns}=(9{^{+1}_{-2}})^\circ$, which was found to be
in strong agreement with the experimental results. In the QLC model the
non-trivial correlation between CKM and PMNS mixing matrices is given by a
correlation matrix ($V_{c}$). We do numerical simulation and estimate the
texture of the $V_{c}$ and in our findings we get a small deviation from the
Tri-Bi-Maximal (TBM) texture and a large from the Bi-Maximal one, which is
consistent with the work already reported in literature. In the further
investigation we obtain quite constrained limits for
$sin^2{\theta_{23}^{pmns}}= 0.4235_{-0.0043}^{+0.0032}$ that is narrower to the
existing ones. We also obtain the constrained limits for the three CP violating
phase invariants $J$, $S_1$ and $S_2$: as $J < 0.0315$, $S_{1} <0.12$ and
$S_{2} <0.08$, respectively.Comment: 18 pages, 10 figure
R\'enyi entropy and conformal defects

We propose a field theoretic framework for calculating the dependence of
R\'enyi entropies on the shape of the entangling surface in a conformal field
theory. Our approach rests on regarding the corresponding twist operator as a
conformal defect and in particular, we define the displacement operator which
implements small local deformations of the entangling surface. We identify a
simple constraint between the coefficient defining the two-point function of
the displacement operator and the conformal weight of the twist operator, which
consolidates a number of distinct conjectures on the shape dependence of the
R\'enyi entropy. As an example, using this approach, we examine a conjecture
regarding the universal coefficient associated with a conical singularity in
the entangling surface for CFTs in any number of spacetime dimensions. We also
provide a general formula for the second order variation of the R\'enyi entropy
arising from small deformations of a spherical entangling surface, extending
Mezei's results for the entanglement entropy.Comment: 37 pages, typos corrected, section 6 and appendix C expanded,

Lepton Flavor Violation in the singlet-triplet scotogenic model

We investigate lepton flavor violation (LFV) in the the singlet-triplet
scotogenic model in which neutrinos acquire non-zero masses at the 1-loop
level. In contrast to the most popular variant of this setup, the singlet
scotogenic model, this version includes a triplet fermion as well as a triplet
scalar, leading to a scenario with a richer dark matter phenomenology. Taking
into account results from neutrino oscillation experiments, we explore some
aspects of the LFV phenomenology of the model. In particular, we study the
relative weight of the dipole operators with respect to other contributions to
the LFV amplitudes and determine the most constraining observables. We show
that in large portions of the parameter space, the most promising experimental
perspectives are found for LFV 3-body decays and for coherent $\mu-e$
conversion in nuclei.Comment: 25 pages, 5 figures; v2:minor changes, matches published versio
The Upper Bound of Radiation Energy in the Myers-Perry Black Hole
  Collision

We have investigated the upper bound of the radiation energy in the head-on
collision of two Myers-Perry black holes. Initially, the two black holes are
far away from each other, and they become one black hole after the collision.
We have obtained the upper bound of the radiation energy thermodynamically
allowed in the process. The upper bound of the radiation energy is obtained in
general dimensions. The radiation bound depends on the alignments of rotating
axes for a given initial condition due to spin-spin interaction. We have found
that the collision may not be occurred for a initially ultra-spinning black
hole.Comment: 12 pages, 15 figures, published version in JHE
Berends-Giele recursion for double-color-ordered amplitudes

Tree-level double-color-ordered amplitudes are computed using Berends--Giele
recursion relations applied to the bi-adjoint cubic scalar theory. The standard
notion of Berends--Giele currents is generalized to double-currents and their
recursions are derived from a perturbiner expansion of linearized fields that
solve the non-linear field equations. Two applications are given. Firstly, we
prove that the entries of the inverse KLT matrix are equal to Berends--Giele
double-currents (and are therefore easy to compute). And secondly, a simple
formula to generate tree-level BCJ-satisfying numerators for arbitrary
multiplicity is proposed by evaluating the field-theory limit of tree-level
string amplitudes for various color orderings using double-color-ordered
amplitudes.Comment: 15 pages, harvmac TeX, v2: published versio
On a residual freedom of the next-to-leading BFKL eigenvalue in color
  adjoint representation in planar $\mathcal{N} = 4$ SYM

We discuss a residual freedom of the next-to-leading BFKL eigenvalue that
originates from ambiguity in redistributing the next-to-leading~(NLO)
corrections between the adjoint BFKL eigenvalue and eigenfunctions in planar
$\mathcal{N}=4$ super-Yang-Mills~(SYM) Theory. In terms of the remainder
function of the Bern-Dixon-Smirnov~(BDS) amplitude this freedom is translated
to reshuffling correction between the eigenvalue and the impact factors in the
multi-Regge kinematics~(MRK) in the next-to-leading logarithm
approximation~(NLA). We show that the modified NLO BFKL eigenvalue suggested by
the authors can be introduced in the MRK expression for the remainder function
by shifting the anomalous dimension in the impact factor in such a way that the
two and three loop remainder function is left unchanged to the NLA accuracy.Comment: 15 pages, 1 figur
6D RG Flows and Nilpotent Hierarchies

With the eventual aim of classifying renormalization group flows between 6D
superconformal field theories (SCFTs), we study flows generated by the vevs of
"conformal matter," a generalization of conventional hypermultiplets which
naturally appear in the F-theory classification of 6D SCFTs. We consider flows
in which the parent UV theory is (on its partial tensor branch) a linear chain
of gauge groups connected by conformal matter, with one flavor group G at each
end of the chain, and in which the symmetry breaking of the conformal matter at
each end is parameterized by the orbit of a nilpotent element, i.e. T-brane
data, of one of these flavor symmetries. Such nilpotent orbits admit a partial
ordering, which is reflected in a hierarchy of IR fixed points. For each such
nilpotent orbit, we determine the corresponding tensor branch for the resulting
SCFT. An important feature of this algebraic approach is that it also allows us
to systematically compute the unbroken flavor symmetries inherited from the
parent UV theory.Comment: v2: 53 pages, 12 figures, clarifications added, typos correcte
Electroweakino pair production at the LHC: NLO SUSY-QCD corrections and
  parton-shower effects

We present a set of NLO SUSY-QCD calculations for the pair production of
neutralinos and charginos at the LHC, and their matching to parton-shower
programs in the framework of the POWHEG-BOX program package. The code we have
developed provides a SUSY Les Houches Accord interface for setting
supersymmetric input parameters. Decays of the neutralinos and charginos and
parton-shower effects can be simulated with PYTHIA. To illustrate the
capabilities of our program, we present phenomenological results for a
representative SUSY parameter point. We find that NLO-QCD corrections increase
the production rates for neutralinos and charginos significantly. The impact of
parton-shower effects on distributions of the weakinos is small, but
non-negligible for jet distributions.Comment: 20 pages, 9 figures. v2: minor changes in text and references,

Decoherence of Topological Qubit in Linear and Circular Motions:
  Decoherence Impedance, Anti-Unruh and Information Backflow

In this paper, we consider the decoherence patterns of a topological qubit
made of two Majorana zero modes in the generic linear and circular motions in
the Minkowski spacetime. We show that the reduced dynamics is exact without
Markov approximation. Our results imply that the acceleration will cause
thermalization as expected by Unruh effect. However, for the short-time scale,
we find the rate of decoherence is anti-correlated with the acceleration, as
kind of decoherence impedance. This is in fact related to the "anti-Unruh"
phenomenon previously found by studying the transition probability of
Unruh-DeWitt detector. We also obtain the information backflow by some time
modulations of coupling constant or acceleration, which is a characteristic of
the underlying non-Markovian reduced dynamics. Moreover, by exploiting the
nonlocal nature of the topological qubit, we find that some incoherent
accelerations of the constituent Majorana zero modes can preserve the coherence
instead of thermalizing it.Comment: 39 pages, 15 figures; v2: typos corrected; v3: minor typos correction

Phase transitions of an anisotropic N=4 super Yang-Mills plasma via
  holography

Black hole solutions of type IIB supergravity were previously found that are
dual to N=4 supersymmetric Yang-Mills plasma with an anisotropic spatial
deformation. In the zero temperature limit, these black holes approach a
Liftshitz like scaling solution in the IR. It was recently shown that these
black holes are unstable, and at low temperatures there is a new class of black
hole solutions that are thermodynamically preferred. We extend this analysis,
by considering consistent truncations of the Kaluza-Klein reduction of IIB
supergravity on a five-sphere that preserves multiple scalar and $U(1)$ gauge
fields. We show that the previously constructed black holes become unstable at
low temperatures, and construct new classes of exotic black hole solutions. We
study the DC thermo-electric conductivity of these $U(1)$ charged black holes,
and find a diverging DC conductivity at zero temperature due to the divergence
of the gauge field coupling.Comment: 30 pages, 8 figure
$Z'$, Higgses and heavy neutrinos in $U(1)'$ models: from the LHC to the
  GUT scale

We study a class of non-exotic minimal $U(1) '$ extensions of the Standard
Model, which includes all scenarios that are anomaly-free with the ordinary
fermion content augmented by one Right-Handed neutrino per generation, wherein
the new Abelian gauge group is spontaneously broken by the non-zero Vacuum
Expectation Value of an additional Higgs singlet field, in turn providing mass
to a $Z'$ state. By adopting the $B-L$ example, whose results can be recast
into those pertaining to the whole aforementioned class, and allowing for both
scalar and gauge mixing, we first extract the surviving parameter space in
presence of up-to-date theoretical and experimental constraints. Over the
corresponding parameter configurations, we then delineate the high energy
behaviour of such constructs in terms of their stability and perturbativity.
Finally, we highlight key production and decay channels of the new states
entering the spectra of this class of models, i.e., heavy neutrinos, a second
Higgs state and the $Z'$, which are amenable to experimental investigation at
the Large Hadron Collider. We therefore set the stage to establish a direct
link between measurements obtainable at the Electro-Weak scale and the dynamics
of the underlying model up to those where a Grand Unification Theory embedding
a $U(1)'$ can be realised.Comment: 32 pages, 59 figures, journal versio
Transport in Chern-Simons-Matter Theories

The frequency-dependent longitudinal and Hall conductivities ---
$\sigma_{xx}$ and $\sigma_{xy}$ --- are dimensionless functions of $\omega/T$
in 2+1 dimensional CFTs at nonzero temperature. These functions characterize
the spectrum of charged excitations of the theory and are basic experimental
observables. We compute these conductivities for large $N$ Chern-Simons theory
with fermion matter. The computation is exact in the 't Hooft coupling
$\lambda$ at $N = \infty$. We describe various physical features of the
conductivity, including an explicit relation between the weight of the delta
function at $\omega = 0$ in $\sigma_{xx}$ and the existence of infinitely many
higher spin conserved currents in the theory. We also compute the
conductivities perturbatively in Chern-Simons theory with scalar matter and
show that the resulting functions of $\omega/T$ agree with the strong coupling
fermionic result. This provides a new test of the conjectured 3d bosonization
duality. In matching the Hall conductivities we resolve an outstanding puzzle
by carefully treating an extra anomaly that arises in the regularization scheme
used.Comment: 27 pages + appendice
Towards Quantum Turbulence in Finite Temperature Bose-Einstein
  Condensates

Motivated by the various indications that holographic superfluid is BCS like
at the standard quantization but BEC like at the alternative quantization, we
have implemented the alternative quantization in the dynamical holographic
superfluid for the first time. With this accomplishment, we further initiate
the detailed investigation of quantum turbulence in finite temperature BEC by a
long time stable numerical simulation of bulk dynamics, which includes the two
body decay of vortex number caused by vortex pair annihilation, the onset of
superfluid turbulence signaled by Kolmogorov scaling law, and a direct energy
cascade demonstrated by injecting energy to the turbulent superfluid. All of
these results share the same patterns as the holographic superfluid at the
standard quantization, thus suggest that these should be universal features for
quantum turbulence at temperatures order of the critical temperature.Comment: 16 pages, 9 figures, 1 table References added and clarifications mad
Diphoton Resonance from a Warped Extra Dimension

We argue that extensions of the Standard Model (SM) with a warped extra
dimension, which successfully address the hierarchy and flavor problems of
elementary particle physics, can provide an elegant explanation of the 750 GeV
diphoton excess recently reported by ATLAS and CMS. A gauge-singlet bulk scalar
with ${\cal O}(1)$ couplings to fermions is identified as the new resonance
$S$, and the vector-like Kaluza-Klein excitations of the SM quarks and leptons
mediate its loop-induced couplings to photons and gluons. The electroweak gauge
symmetry almost unambiguously dictates the bulk matter content and hence the
hierarchies of the $S\to \gamma\gamma$, $WW$, $ZZ$, $Z\gamma$, $t\bar t$ and
dijet decay rates. We find that the $S\to Z\gamma$ decay mode is strongly
suppressed, such that $\mbox{Br}(S\to
Z\gamma)/\mbox{Br}(S\to\gamma\gamma)<0.1$. The hierarchy problem for the new
scalar boson is solved in analogy with the Higgs boson by localizing it near
the infrared brane. The infinite sums over the Kaluza-Klein towers of fermion
states are finite and can be calculated in closed form with a remarkably simple
result. Reproducing the observed $pp\to S\to\gamma\gamma$ signal requires
Kaluza-Klein masses in the multi-TeV range, consistent with bounds from flavor
physics and electroweak precision observables.
  Useful side products of our analysis, which can be adapted to almost any
model for the diphoton resonance, are the calculation of the gluon-fusion
production cross section $\sigma(pp\to S)$ at NNLO in QCD, an exact expression
for the inclusive $S\to gg$ decay rate at N$^3$LO, a study of the $S\to t\bar t
h$ three-body decay and a phenomenological analysis of portal couplings
connecting $S$ with the Higgs field.Comment: 31 pages, 7 figures, 3 tables; v2: typos fixed and some references

Signatures of sneutrino dark matter in an extension of the CMSSM

Current data (LHC direct searches, Higgs mass, dark matter-related bounds)
severely affect the constrained minimal SUSY standard model (CMSSM) with
neutralinos as dark matter candidates. But the evidence for neutrino masses
coming from oscillations requires extending the SM with at least right-handed
neutrinos with a Dirac mass term. In turn, this implies extending the CMSSM
with right-handed sneutrino superpartners, a scenario we dub $\tilde\nu$CMSSM.
These additional states constitute alternative dark matter candidates of the
superWIMP type, produced via the decay of the long-lived next-to-lightest SUSY
particle (NLSP). Here we consider the interesting and likely case where the
NLSP is a $\tilde{\tau}$: despite the modest extension with respect to the
CMSSM this scenario has the distinctive signatures of heavy, stable charged
particles. After taking into account the role played by neutrino mass bounds
and the specific cosmological bounds from the big bang nucleosynthesis in
selecting the viable parameter space, we discuss the excellent discovery
prospects for this model at the future runs of the LHC. We show that it is
possible to probe $\tilde{\tau}$ masses up to 600 GeV at the 14 TeV LHC with
$\mathcal{L} = 1100$ fb$^{-1}$ when one considers a pair production of staus
with two or more hard jets through all SUSY processes. We also show the
complementary discovery prospects from a direct $\tilde{\tau}$ pair production,
as well as at the new experiment MoEDAL.Comment: 31 pages, 6 figures and 5 tables; v2 : discussions and references

Marginal Breaking of Conformal SUSY QCD

We provide an example of a 4D theory that exhibits the
Contino-Pomarol-Rattazzi mechanism, where breaking conformal symmetry by an
almost marginal operator leads to a light pseudo-Goldstone boson, the dilaton,
and a parametrically suppressed contribution to vacuum energy. We consider SUSY
QCD at the edge of the conformal window and break conformal symmetry by weakly
gauging a subgroup of the flavor symmetry. Using Seiberg duality we show that
for a range of parameters the singlet meson in the dual theory reaches the
unitarity bound, however, this theory does not have a stable vacuum. We
stabilize the vacuum with soft breaking terms, compute the mass of the dilaton,
and determine the range of parameters where the leading contribution to the
dilaton mass is from the almost marginal coupling.Comment: 12 pages, no figure
Flavor hierarchies from dynamical scales

One main obstacle for any beyond the SM (BSM) scenario solving the hierarchy
problem is its potentially large contributions to electric dipole moments. An
elegant way to avoid this problem is to have the light SM fermions couple to
the BSM sector only through bilinears, $\bar ff$. This possibility can be
neatly implemented in composite Higgs models. We study the implications of
dynamically generating the fermion Yukawa couplings at different scales,
relating larger scales to lighter SM fermions. We show that all flavor and
CP-violating constraints can be easily accommodated for a BSM scale of few TeV,
without requiring any extra symmetry. Contributions to B physics are mainly
mediated by the top, giving a predictive pattern of deviations in $\Delta F=2$
and $\Delta F=1$ flavor observables that could be seen in future experiments.Comment: 25 pages, 5 figures; v2: corrections in some estimate
The leading twist light-cone distribution amplitudes for the S-wave and
  P-wave Bc mesons

The light-cone distribution amplitudes (LCDAs) serve as important
non-perturbative inputs for the study of hard exclusive processes. In this
paper, we calculate ten LCDAs at twist-2 for the S-wave and P-wave $B_c$ mesons
up to the next-to-leading order (NLO) of the strong coupling $\alpha_s$ and
leading order of the velocity expansion. Each one of these ten LCDAs is
expressed as a product of a perturbatively calculable distribution and a
universal NRQCD matrix-element. By use of the spin symmetry, only two NRQCD
matrix-elements will be involved. The reduction of the number of
non-perturbative inputs will improve the predictive power of collinear
factorization.Comment: 20 pages, no figure. Match to the published version in JHE
Path integral for multi-field inflation

We develop the path integral formalism for studying cosmological
perturbations in multi-field inflation, which is particularly well suited to
study quantum theories with gauge symmetries such as diffeomorphism invariance.
We formulate the gauge fixing conditions based on the Poisson brackets of the
constraints, from which we derive two convenient gauges that are appropriate
for multi-field inflation. We then adopt the in-in formalism to derive the most
general expression for the power spectrum of the curvature perturbation
including the corrections from the interactions of the curvature mode with
other light degrees of freedom. We also discuss the contributions of the
interactions to the bispectrum.Comment: (v1) 27 pages; (v2) references added and typos corrected, to appear

Tensor Networks from Kinematic Space

We point out that the MERA network for the ground state of a 1+1-dimensional
conformal field theory has the same structural features as kinematic
space---the geometry of CFT intervals. In holographic theories kinematic space
becomes identified with the space of bulk geodesics studied in integral
geometry. We argue that in these settings MERA is best viewed as a
discretization of the space of bulk geodesics rather than of the bulk geometry
itself. As a test of this kinematic proposal, we compare the MERA
representation of the thermofield-double state with the space of geodesics in
the two-sided BTZ geometry, obtaining a detailed agreement which includes the
entwinement sector. We discuss how the kinematic proposal can be extended to
excited states by generalizing MERA to a broader class of compression networks.Comment: 35 pages, 17 figure
The Higgs of the Higgs and the diphoton channel

LHC results do not confirm conventional natural solutions to the Higgs mass
hierarchy problem, motivating alternative interpretations where a
hierarchically small weak scale is generated from a dimension-less quantum
dynamics. We propose weakly and strongly-coupled models where the field that
breaks classical scale invariance giving mass to itself and to the Higgs is
identified with a possible new resonance within the LHC reach. As an example,
we identify such resonance with the 750 GeV diphoton excess recently reported
by ATLAS and CMS. Such models can be extrapolated up to the Planck scale,
provide Dark Matter candidates and eliminate the SM vacuum instability.Comment: 23 pages, 4 figures; one figure added and title and other wording

The Higgs mass and the scale of SUSY breaking in the NMSSM

In this letter we study the Higgs mass in the NMSSM with supersymmetry
breaking at high scales $M_{SS}$. With the Standard Model as the effective low
energy theory, the computation of the Higgs mass relies on the matching
condition of the quartic coupling $\lambda$ at $M_{SS}$. In the MSSM, the
latter is fixed to a semi-positive value and, thus, sets an upper bound on the
SUSY-breaking scale near $M_{SS}\simeq 10^{10}\text{GeV}$. In the NMSSM,
$\lambda(M_{SS})$ receives an additional contribution induced by the singlet
which allows for negative values of $\lambda(M_{SS})$. In turn, for the
measured value of the Higgs mass we find that $M_{SS}$ can take any value up to
the GUT scale. Furthermore, the choice of universal soft terms favors
SUSY-breaking scales close to the GUT scale.Comment: 14 pages, 5 figure
