Self-dual configurations in Abelian Higgs models with $k$-generalized
  gauge field dynamics

We have shown the existence of self-dual solutions in new Maxwell-Higgs
scenarios where the gauge field possesses a $k$-generalized dynamic, i.e., the
kinetic term of gauge field is a highly nonlinear function of
$F_{\mu\nu}F^{\mu\nu}$. We have implemented our proposal by means of a
$k$-generalized model displaying the spontaneous symmetry breaking phenomenon.
We implement consistently the Bogomol'nyi-Prasad-Sommerfield formalism
providing highly nonlinear self-dual equations whose solutions are electrically
neutral possessing total energy proportional to the magnetic flux. Among the
infinite set of possible configurations, we have found families of
$k$-generalized models whose self-dual equations have a form mathematically
similar to the ones arising in the Maxwell-Higgs or Chern-Simons-Higgs models.
Furthermore, we have verified that our proposal also supports infinite twinlike
models with $|\phi|^4$-potential or $|\phi |^6$-potential. With the aim to show
explicitly that the BPS equations are able to provide well-behaved
configurations, we have considered a test model in order to study axially
symmetric vortices. By depending of the self-dual potential, we have shown that
the $k$-generalized model is able to produce solutions that for long distances
have a exponential decay (as Abrikosov-Nielsen-Olesen vortices) or have a
power-law decay (characterizing delocalized vortices). In all cases, we observe
that the generalization modifies the vortex core size, the magnetic field
amplitude and the bosonic masses but the total energy remains proportional to
the quantized magnetic flux.Comment: 11 pages, Latex 2e, 12 figures; major revisio
Global Effective-Field-Theory analysis of New-Physics effects in
  (semi)leptonic kaon decays

We analyze the decays $K\to\pi\ell\nu$ and $P\to\ell\nu$ ($P=K,\pi$,
$\ell=e,\,\mu$) using a low-energy Effective-Field-Theory approach to
parametrize New Physics and study the complementarity with baryon $\beta$
decays. We then provide a road map for a global analysis of the experimental
data, with all the Wilson coefficients simultaneously, and perform a fit
leading to numerical bounds for them and for $V_{us}$. A prominent result of
our analysis is a reinterpretation of the well-known $V_{ud}-V_{us}$ diagram as
a strong constraint on new physics. Finally, we reinterpret our bounds in terms
of the $SU(2)_L\times~U(1)_Y$-invariant operators, provide bounds to the
corresponding Wilson coefficients at the TeV scale and compare our results with
collider searches at the LHC.Comment: 45 pages, 4 figures; v2: minor changes to match version published in

New Gravitational Memories

The conventional gravitational memory effect is a relative displacement in
the position of two detectors induced by radiative energy flux. We find a new
type of gravitational `spin memory' in which beams on clockwise and
counterclockwise orbits acquire a relative delay induced by radiative angular
momentum flux. It has recently been shown that the displacement memory formula
is a Fourier transform in time of Weinberg's soft graviton theorem. Here we see
that the spin memory formula is a Fourier transform in time of the
recently-discovered subleading soft graviton theorem.Comment: 17 page
Avoiding the Goldstone Boson Catastrophe in general renormalisable field
  theories at two loops

We show how the infra-red divergences associated to Goldstone bosons in the
minimum condition of the two-loop Landau-gauge effective potential can be
avoided in general field theories. This extends the resummation formalism
recently developed for the Standard Model and the MSSM, and we give compact,
infra-red finite expressions in closed form for the tadpole equations. We also
show that the results at this loop order are equivalent to (and are most easily
obtained by) imposing an "on-shell" condition for the Goldstone bosons.
Moreover, we extend the approach to show how the infra-red divergences in the
calculation of the masses of neutral scalars (such as the Higgs boson) can be
eliminated. For the mass computation, we specialise to the gaugeless limit and
extend the effective potential computation to allow the masses to be determined
without needing to solve differential equations for the loop functions --
opening the door to fast, infra-red safe determinations of the Higgs mass in
general theories.Comment: 42 pages, one figure; v2: corrected typos and added explanation
$\phi^3$ theory with $F_4$ flavor symmetry in $6-2\epsilon$ dimensions:
  3-loop renormalization and conformal bootstrap

We consider $\phi^3$ theory in $6-2\epsilon$ with $F_4$ global symmetry. The
beta function is calculated up to 3 loops, and a stable unitary IR fixed point
is observed. The anomalous dimensions of operators quadratic or cubic in $\phi$
are also computed. We then employ conformal bootstrap technique to study the
fixed point predicted from the perturbative approach. For each putative scaling
dimension of $\phi$ ($\Delta_{\phi})$, we obtain the corresponding upper bound
on the scaling dimension of the second lowest scalar primary in the ${\mathbf
26}$ representation $(\Delta^{\rm 2nd}_{{\mathbf 26}})$ which appears in the
OPE of $\phi\times\phi$. In $D=5.95$, we observe a sharp peak on the upper
bound curve located at $\Delta_{\phi}$ equal to the value predicted by the
3-loop computation. In $D=5$, we observe a weak kink on the upper bound curve
at $(\Delta_{\phi},\Delta^{\rm 2nd}_{{\mathbf 26}})$=$(1.6,4)$.Comment: 22 pages, published versio
Six-dimensional Origin of $\mathcal{N}=4$ SYM with Duality Defects

We study the topologically twisted compactification of the 6d $(2,0)$
M5-brane theory on an elliptically fibered K\"ahler three-fold preserving two
supercharges. We show that upon reducing on the elliptic fiber, the 4d theory
is $\mathcal{N}=4$ Super-Yang Mills, with varying complexified coupling $\tau$,
in the presence of defects. For abelian gauge group this agrees with the
so-called duality twisted theory, and we determine a non-abelian generalization
to $U(N)$. When the elliptic fibration is singular, the 4d theory contains 3d
walls (along the branch-cuts of $\tau$) and 2d surface defects, around which
the 4d theory undergoes $SL(2,\mathbb{Z})$ duality transformations. Such
duality defects carry chiral fields, which from the 6d point of view arise as
modes of the two-form $B$ in the tensor multiplet. Each duality defect has a
flavor symmetry associated to it, which is encoded in the structure of the
singular elliptic fiber above the defect. Generically 2d surface defects will
intersect in points in 4d, where there is an enhanced flavor symmetry. The 6d
point of view provides a complete characterization of this 4d-3d-2d-0d
`Matroshka'-defect configuration.Comment: 62 pages, 4 figure
Type I/heterotic duality and M-theory amplitudes

This paper investigates relationships between low-energy four-particle
scattering amplitudes with external gauge particles and gravitons in the E_8 X
E_8 and SO(32) heterotic string theories and the type I and type IA superstring
theories by considering a variety of tree level and one-loop Feynman diagrams
describing such amplitudes in eleven-dimensional supergravity in a
Horava--Witten background compactified on a circle. This accounts for a number
of perturbative and non-perturbative aspects of low order higher derivative
terms in the low-energy expansion of string theory amplitudes, which are
expected to be protected by half maximal supersymmetry from receiving
corrections beyond one or two loops. It also suggests the manner in which type
I/heterotic duality may be realised for certain higher derivative interactions
that are not so obviously protected. For example, our considerations suggest
that R**4 interactions (where R is the Riemann curvature) might receive no
perturbative corrections beyond one loop by virtue of a conspiracy involving
contributions from (non-BPS) Z2 D-instantons in the type I and heterotic SO(32)
theories.Comment: Typos corrected. Subsection 8.2 added. Section 8 modified. Version to

Scattering effect on entanglement propagation in RCFTs

In this paper we discuss the scattering effect on entanglement propagation in
RCFTs. In our setup, we consider the time evolution of excited states created
by the insertion of many local operators. Our results show that because of the
finiteness of quantum dimension, entanglement is not changed after the
scattering in RCFTs. In this mean, entanglement is conserved after the
scattering event in RCFTs, which reflects the integrability of the system. Our
results are also consistent with the free quasiparticle picture after the
global quenches.Comment: 26 pages, Latex, 13 figures, reference adde
Di-Higgs signatures from R-parity violating supersymmetry as the origin
  of neutrino mass

Motivated by the naturalness and neutrino mass generation, we study a
bilinear R-parity violating supersymmetric scenario with a light Higgsino-like
lightest supersymmetric particle (LSP). We observe that the LSP dominantly
decays to $\nu h$ in a large part of the parameter space, and thus study the
pair production of electroweakinos followed by the decays $\tilde\chi^\pm_1\to
\tilde\chi^0_1 W^{\pm*}$ and $\tilde\chi^0_1\to \nu h$. This leads to an
interesting signature of Higgs boson pair production associated with
significantly large missing transverse energy which is grossly distinct from
the di-Higgs production in the Standard Model. We investigate the perspective
of probing such signatures by performing a realistic detector level simulation
of both the signal and corresponding backgrounds for the high-luminosity high
energy phase of the Large Hadron Collider (LHC). We also advocate some
observables based on kinematical features to provide an excellent handle to
suppress the backgrounds.Comment: 26 pages, 11 figures and 6 table
Wilson punctured network defects in 2D q-deformed Yang-Mills theory

In the context of class S theories and 4D/2D duality relations there, we
discuss the skein relations of general topological defects on the 2D side which
are expected to be counterparts of composite surface-line operators in 4D class
S theory. Such defects are geometrically interpreted as networks in a three
dimensional space. We also propose a conjectural computational procedure for
such defects in two dimensional SU(N) topological q-deformed Yang-Mills theory
by interpreting it as a statistical mechanical system associated with ideal
triangulations.Comment: v3:JHEP published version (more several corrections and

Static configurations and evolution of higher dimensional brane-dilaton
  black hole system

Static configurations and a dynamical evolution of the system composed of a
higher-dimensional spherically symmetric dilaton black hole and the
Dirac-Goto-Nambu brane were investigated. The studies were conducted for three
values of the dilaton coupling constant, describing the uncoupled case, the
low-energy limit of the string theory and dimensionally reduced Klein-Kaluza
theories. When the black hole is nonextremal, two types of static
configurations are observed, a brane which intersects the black hole horizon
and a brane not having any common points with the accompanying black hole. As
the number of spacetime dimensions increases, the brane bend in the vicinity of
the black hole disappears closer to its horizon. Dynamical evolution of the
system results in an expulsion of the black hole from the brane. It proceeds
faster for bigger values of the bulk spacetime dimension and thicker branes.
The value of the dilatonic coupling constant does not influence neither the
static configurations nor the dynamical behavior of the examined nonextremal
system. In the extremal dilaton black hole case one obtains expulsion of the
brane which is independent on the spacetime dimensionality and the value of the
coupling constant. Dynamical studies of the configurations in the extremal case
reveal that the course of evolution of the system is similar to the nonextremal
one, except for a slightly earlier expulsion of the black hole from the brane.Comment: 23 pages, 7 figure
Collapse of Axion Stars

Axion stars, gravitationally bound states of low-energy axion particles, have
a maximum mass allowed by gravitational stability. Weakly bound states
obtaining this maximum mass have sufficiently large radii such that they are
dilute, and as a result, they are well described by a leading-order expansion
of the axion potential. Heavier states are susceptible to gravitational
collapse. Inclusion of higher-order interactions, present in the full
potential, can give qualitatively different results in the analysis of
collapsing heavy states, as compared to the leading-order expansion. In this
work, we find that collapsing axion stars are stabilized by repulsive
interactions present in the full potential, providing evidence that such
objects do not form black holes. In the last moments of collapse, the binding
energy of the axion star grows rapidly, and we provide evidence that a large
amount of its energy is lost through rapid emission of relativistic axions.Comment: 21 pages, 7 figures. v2: Figure added, typos corrected, text

Non-Abelian 3d Bosonization and Quantum Hall States

Bosonization dualities relate two different Chern-Simons-matter theories,
with bosonic matter on one side replaced by fermionic matter on the other. We
first describe a more general class of non-Abelian bosonization dualities. We
then explore the non-relativistic physics of these theories in the quantum Hall
regime. The bosonic theory lies in a condensed phase and admits vortices which
are known to form a non-Abelian quantum Hall state. We ask how this same
physics arises in the fermionic theory. We find that a condensed boson
corresponds to a fully filled Landau level of fermions, while bosonic vortices
map to fermionic holes. We confirm that the ground state of the two theories is
indeed described by the same quantum Hall wavefunction.Comment: 21 pages. v2: typo corrected. v3: another typo corrected (chemical

Search for a lighter Higgs in Two Higgs Doublet Models

We consider present constraints on Two Higgs Doublet Models, both from the
LHC at Run 1 and from other sources in order to explore the possibility of
constraining a neutral scalar or pseudo-scalar particle lighter than the 125
GeV Higgs boson. Such a lighter particle is not yet completely excluded by
present data. We show with a simplified analysis that some new constraints
could be obtained at the LHC if such a search is performed by the experimental
collaborations, which we therefore encourage to continue carrying out light
diphoton resonance searches at $\sqrt{s}=$ 13 TeV in the context of Two Higgs
Doublet Models.Comment: 29 pages, 9 tables, 18 figures (minor text modifications in v2
Quantum Entanglement of Locally Excited States in Maxwell Theory

In 4 dimensional Maxwell gauge theory, we study the changes of (Renyi)
entangle-ment entropy which are defined by subtracting the entropy for the
ground state from the one for the locally excited states generated by acting
with the gauge invariant local operators on the state. The changes for the
operators which we consider in this paper reflect the electric-magnetic
duality. The late-time value of changes can be interpreted in terms of
electromagnetic quasi-particles. When the operator constructed of both electric
and magnetic fields acts on the ground state, it shows that the operator acts
on the late-time structure of quantum entanglement differently from free scalar
fields.Comment: 23 pages, 4 figure
Many-point classical conformal blocks and geodesic networks on the
  hyperbolic plane

We study the semiclassical holographic correspondence between 2d CFT n-point
conformal blocks and massive particle configurations in the asymptotically AdS3
space. On the boundary we use the heavy-light approximation in which case two
of primary operators are the background for the other (n-2) operators
considered as fluctuations. In the bulk the particle dynamics can be reduced to
the hyperbolic time slice. Although lacking exact solutions we nevertheless
show that for any n the classical n-point conformal block is equal to the
length of the dual geodesic network connecting n-3 cubic vertices of worldline
segments. To this end, both the bulk and boundary systems are reformulated as
potential vector fields. Gradients of the conformal block and geodesic length
are given respectively by accessory parameters of the monodromy problem and
particle momenta of the on-shell worldline action represented as a function of
insertion points. We show that the accessory parameters and particle momenta
are constrained by two different algebraic equation systems which nevertheless
have the same roots thereby guaranteeing the correspondence.Comment: 29 page
Disordered Quivers and Cold Horizons

We analyze the low temperature structure of a supersymmetric quiver quantum
mechanics with randomized superpotential coefficients, treating them as
quenched disorder. These theories describe features of the low energy dynamics
of wrapped branes, which in large number backreact into extremal black holes.
We show that the low temperature theory, in the limit of a large number of
bifundamentals, exhibits a time reparametrization symmetry as well as a
specific heat linear in the temperature. Both these features resemble the
behavior of black hole horizons in the zero temperature limit. We demonstrate
similarities between the low temperature physics of the random quiver model and
a theory of large $N$ free fermions with random masses.Comment: 25 pages, 1 figure, v2 minor changes references added, v3 typos

Invariants for minimal conformal supergravity in six dimensions

We develop a new off-shell formulation for six-dimensional conformal
supergravity obtained by gauging the 6D ${\cal N} = (1, 0)$ superconformal
algebra in superspace. This formulation is employed to construct two invariants
for 6D ${\cal N} = (1, 0)$ conformal supergravity, which contain $C^3$ and
$C\Box C$ terms at the component level. Using a conformal supercurrent
analysis, we prove that these exhaust all such invariants in minimal conformal
supergravity. Finally, we show how to construct the supersymmetric $F \Box F$
invariant in curved superspace.Comment: 52 pages; V2: published versio
Flavor Cosmology: Dynamical Yukawas in the Froggatt-Nielsen Mechanism

Can the cosmological dynamics responsible for settling down the present
values of the Cabibbo-Kobayashi-Maskawa matrix be related to electroweak
symmetry breaking? If the Standard Model Yukawa couplings varied in the early
universe and started with order one values before electroweak symmetry
breaking, the CP violation associated with the CKM matrix could be the origin
of the matter-antimatter asymmetry. The large effective Yukawa couplings which
lead to the enhanced CP violation can also help in achieving a strong
first-order electroweak phase transition. We study in detail the feasibility of
this idea by implementing dynamical Yukawa couplings in the context of the
Froggatt--Nielsen mechanism. We discuss two main realizations of such a
mechanism, related phenomenology, cosmological and collider bounds, and provide
an estimate of the baryonic yield. A generic prediction is that this scenario
always features a new scalar field below the electroweak scale. We point out
ways to get around this conclusion.Comment: 41 pages, 14 figures; v2:Section 4.3 updated with corrected figures 2

New LUX and PandaX-II Results Illuminating the Simplest Higgs-Portal
  Dark Matter Models

Direct searches for dark matter (DM) by the LUX and PandaX-II Collaborations
employing xenon-based detectors have recently come up with the most stringent
limits to date on the spin-independent elastic scattering of DM off nucleons.
For Higgs-portal scalar DM models, the new results have precluded any
possibility of accommodating low-mass DM as suggested by the DAMA and CDMS II
Si experiments utilizing other target materials, even after invoking
isospin-violating DM interactions with nucleons. In the simplest model, SM+D,
which is the standard model plus a real singlet scalar named darkon acting as
the DM candidate, the LUX and PandaX-II limits rule out DM masses roughly from
4 to 450 GeV, except a small range around the resonance point at half of the
Higgs mass where the interaction cross-section is near the neutrino-background
floor. In the THDM II+D, which is the type-II two-Higgs-doublet model combined
with a darkon, the region excluded in the SM+D by the direct searches can be
recovered due to suppression of the DM effective interactions with nucleons at
some values of the ratios of Higgs couplings to the up and down quarks, making
the interactions significantly isospin-violating. However, in either model, if
the 125-GeV Higgs boson is the portal between the dark and SM sectors, DM
masses less than 50 GeV or so are already ruled out by the LHC constraint on
the Higgs invisible decay. In the THDM II+D, if the heavier $CP$-even Higgs
boson is the portal, theoretical restrictions from perturbativity, vacuum
stability, and unitarity requirements turn out to be important instead and
exclude much of the region below 100 GeV. For larger DM masses, the THDM II+D
has plentiful parameter space that corresponds to interaction cross-sections
under the neutrino-background floor and therefore is likely to be beyond the
reach of future direct searches without directional sensitivity.Comment: 25 pages, 11 figures, somewhat enlarged, references added, main

Grassmannians and form factors with $q^2=0$ in N=4 SYM theory

We consider tree level form factors of operators from stress tensor operator

several known answers in $\mbox{MHV}$ and $\mbox{N}^{k-2}\mbox{MHV}$, $k\geq3$

of spurious poles and relations between different BCFW representations for such

A Note on Vectorial AdS$_5$/CFT$_4$ Duality for Spin-$j$ Boundary Theory

The vectorial holographic correspondences between higher-spin theories in
AdS$_5$ and free vector models on the boundary are extended to the cases where
the latter is described by free massless spin-$j$ field. The dual higher-spin
theory in the bulk does not include gravity and can only be defined on rigid
AdS$_5$ background with $S^4$ boundary. We discuss various properties of these
rather special higher-spin theories and calculate their one-loop free energies.
We show that the result is proportional to the same quantity for spin-$j$
doubleton treated as if it is a AdS$_5$ field. Finally, we consider even more
special case where the boundary theory itself is given by an infinite tower of
massless higher-spin fields.Comment: 27 pages, version to appear in JHE
