Fermion Dark Matter in Gauge-Higgs Unification

We propose a Majorana fermion dark matter in the context of a simple
gauge-Higgs Unification (GHU) scenario based on the gauge group $SU(3)$ x
$U(1)'$ in 5-dimensional Minkowski space with a compactification of the 5th
dimension on $S^1/Z_2$ orbifold. The dark matter particle is identified with
the lightest mode in $SU(3)$ triplet fermions additionally introduced in the
5-dimensional bulk. We find an allowed parameter region for the dark matter
mass around a half of the Standard Model Higgs boson mass, which is consistent
with the observed dark matter density and the constraint from the LUX 2016
result for the direct dark matter search. The entire allowed region will be
covered by, for example, the LUX-ZEPLIN dark matter experiment in the near
future. We also show that in the presence of the bulk $SU(3)$ triplet fermions
the 125 GeV Higgs boson mass is reproduced through the renormalization group
evolution of Higgs quartic coupling with the compactification scale of around
$10^8$ GeV.Comment: 21 pages, 5 figures , published version in JHE
Chiral boundary conditions for singletons and W-branes

We revisit the holographic dictionary for a free massless scalar in AdS$_3$,
focusing on the `singleton' solutions for which the boundary profile is an
arbitrary chiral function. We look for consistent boundary conditions which
include this class of solutions. On one hand, we give a no-go argument that
they cannot be interpreted within any boundary condition which preserves full
conformal invariance. On the other hand, we show that such solutions fit
naturally in a generalization of the Comp\`{e}re-Song-Strominger boundary
conditions, which preserve a chiral Virasoro and current algebra. These
observations have implications for the black hole deconstruction proposal,
which proposes singleton solutions as candidate black hole microstate
geometries. Our results suggest that the chiral boundary condition, which also
contains the extremal BTZ black hole, is the natural setting for
holographically interpreting the black hole deconstruction proposal.Comment: 25p+appendices, 2 figures, published versio
Spin-dependent constraints on blind spots for thermal singlino-higgsino
  dark matter with(out) light singlets

The LUX experiment has recently set very strong constraints on
spin-independent interactions of WIMP with nuclei. These null results can be
accommodated in NMSSM provided that the effective spin-independent coupling of
the LSP to nucleons is suppressed. We investigate thermal relic abundance of
singlino-higgsino LSP in these so-called spin-independent blind spots and
derive current constraints and prospects for direct detection of spin-dependent
interactions of the LSP with nuclei providing strong constraints on parameter
space. We show that if the Higgs boson is the only light scalar the new LUX
constraints set a lower bound on the LSP mass of about 300 GeV except for a
small range around the half of $Z^0$ boson masses where resonant annihilation
via $Z^0$ exchange dominates. XENON1T will probe entire range of LSP masses
except for a tiny $Z^0$-resonant region that may be tested by the LZ
experiment. These conclusions apply to general singlet-doublet dark matter
annihilating dominantly to $t\bar{t}$. Presence of light singlet
(pseudo)scalars generically relaxes the constraints because new LSP (resonant
and non-resonant) annihilation channels become important. Even away from
resonant regions, the lower limit on the LSP mass from LUX is relaxed to about
250 GeV while XENON1T may not be sensitive to the LSP masses above about 400
GeV.Comment: 31 pages, 8 figure
On the Bethe states of the one-dimensional supersymmetric t-J model with
  generic open boundaries

By combining the algebraic Bethe ansatz and the off-diagonal Bethe ansatz, we
investigate the supersymmetric t-J model with generic open boundaries. The
eigenvalues of the transfer matrix are given in terms of an inhomogeneous T-Q
relation, and the corresponding eigenstates are expressed in terms of nested
Bethe states which have well-defined homogeneous limit. This exact solution
provides basis for further analyzing the thermodynamic properties and
correlation functions of the model.Comment: 17 pages, 2 tables, published versio
Quadrality for Supersymmetric Matrix Models

We introduce a new duality for $\mathcal{N}=1$ supersymmetric gauged matrix
models. This $0d$ duality is an order 4 symmetry, namely an equivalence between
four different theories, hence we call it Quadrality. Our proposal is motivated
by mirror symmetry, but is not restricted to theories with a D-brane
realization and holds for general $\mathcal{N}=1$ matrix models. We present
various checks of the proposal, including the matching of: global symmetries,
anomalies, deformations and the chiral ring. We also consider quivers and the
corresponding quadrality networks. Finally, we initiate the study of matrix
models that arise on the worldvolume of D(-1)-branes probing toric Calabi-Yau
5-folds.Comment: 46 pages, 18 figure
Diffusivities bounds and chaos in holographic Horndeski theories

We study the thermoelectric DC conductivities of Horndeski holographic models
with momentum dissipation. We compute the butterfly velocity $v_B$ and we
discuss the existence of universal bounds on charge and energy diffusivities in
the incoherent limit related to quantum chaos. We find that the Horndeski
coupling represents a subleading contribution to the thermoelectric
conductivities in the incoherent limit and therefore it does not affect any of
the proposed bounds.Comment: 16 pages + 3 appendices, 2 figures; v2: references added, typo

Non-local Geometry inside Lifshitz Horizon

Based on the quantum renormalization group, we derive the bulk geometry that
emerges in the holographic dual of the fermionic U(N) vector model at a nonzero
charge density. The obstruction that prohibits the metallic state from being
smoothly deformable to the direct product state under the renormalization group
flow gives rise to a horizon at a finite radial coordinate in the bulk. The
region outside the horizon is described by the Lifshitz geometry with a
higher-spin hair determined by microscopic details of the boundary theory. On
the other hand, the interior of the horizon is not described by any Riemannian
manifold, as it exhibits an algebraic non-locality. The non-local structure
inside the horizon carries the information on the shape of the filled Fermi
sea.Comment: 20 page
$\overline{D3}$ Induced Geometric Inflation

Effective supergravity inflationary models induced by anti-D3 brane
interaction with the moduli fields in the bulk geometry have a geometric
description. The K\"ahler function carries the complete geometric information
on the theory. The non-vanishing bisectional curvature plays an important role
in the construction. The new geometric formalism, with the nilpotent superfield
representing the anti-D3 brane, allows a powerful generalization of the
existing inflationary models based on supergravity. They can easily incorporate
arbitrary values of the Hubble parameter, cosmological constant and gravitino
mass. We illustrate it by providing generalized versions of polynomial chaotic
inflation, T- and E-models of $\alpha$-attractor type, disk merger. We also
describe a multi-stage cosmological attractor regime, which we call cascade
inflation.Comment: 22 pages, 7 figures, v2: typos corrected, v3: references adde
(Higgs) vacuum decay during inflation

We develop the formalism for computing gravitational corrections to vacuum
decay from de Sitter space as a sub-Planckian perturbative expansion.
Non-minimal coupling to gravity can be encoded in an effective potential. The
Coleman bounce continuously deforms into the Hawking-Moss bounce, until they
coincide for a critical value of the Hubble constant. As an application, we
reconsider the decay of the electroweak Higgs vacuum during inflation. Our
vacuum decay computation reproduces and improves bounds on the maximal
inflationary Hubble scale previously computed through statistical techniques.Comment: 23 pages, 5 figures; references added, matches version published in

On timelike supersymmetric solutions of Abelian gauged 5-dimensional
  supergravity

We consider 5-dimensional gauged supergravity coupled to Abelian vector
multiplets, and we look for supersymmetric solutions for which the
4-dimensional K\"ahler base space admits a holomorphic isometry. Taking
advantage of this isometry, we are able to find several supersymmetric
solutions for the ST$[2,n_v+1]$ special geometric model with arbitrarily many
vector multiplets. Among these there are three families of solutions with
$n_v+2$ independent parameters, which for one of the families can be seen to
correspond to $n_v+1$ electric charges and one angular momentum. These
solutions generalize the ones recently found for minimal gauged supergravity in
JHEP 1704 (2017) 017 and include in particular the general supersymmetric
asymptotically-AdS$_5$ black holes of Gutowski and Reall, analogous black hole
solutions with non-compact horizon, the three near horizon geometries
themselves, and the singular static solutions of Behrndt, Chamseddine and
Sabra.Comment: 29 page
${\cal W}$ algebras are L$_\infty$ algebras

It is shown that the closure of the infinitesimal symmetry transformations
underlying classical ${\cal W}$ algebras give rise to L$_\infty$ algebras with
in general field dependent gauge parameters. Therefore, the class of well
understood ${\cal W}$ algebras provides highly non-trivial examples of such
strong homotopy Lie-algebras. We develop the general formalism for this
correspondence and apply it explicitly to the classical ${\cal W}_3$ algebra.Comment: 15 pages; v2: typos corrected, minor change
Superconformal Blocks for SCFTs with Eight Supercharges

We show how to treat the superconformal algebras with eight Poincar\'e
supercharges in a unified manner for spacetime dimension $2 < d\leq 6$. This
formalism is ideally suited for analyzing the quadratic Casimir operator of the
superconformal algebra and its use in deriving superconformal blocks. We
illustrate this by an explicit construction of the superconformal blocks, for
any value of the spacetime dimension, for external protected scalar operators
which are the lowest component of flavor current multiplets.Comment: 20+9 pages, v2: references added, v3: added closed formulas for the

N=2 Chern-Simons-Matter Theories Without Vortices

We study ${\cal N}=2$ Chern-Simons-matter theories with gauge group
$U_{k_1}(1)\times U_{k_2}(1)$. We find that, when $k_1+k_2=0$, the partition
function computed by localization dramatically simplifies and collapses to a
single term. We show that the same condition prevents the theory from having
supersymmetric vortex configurations. The theories include mass-deformed ABJM
theory with $U(1)_{k}\times U_{-k}(1)$ gauge group as a particular case.
Similar features are shared by a class of CS-matter theories with gauge group
$U_{k_1}(1)\times \cdots \times U_{k_N}(1)$.Comment: 17 page
Families of gauge conditions in BV formalism

In BV formalism we can consider a Lagrangian submanifold as a gauge
condition. Starting with the BV action functional we construct a closed form on
the space of Lagrangian submanifolds. If the action functional is invariant
with respect to some group $H$ and $\Lambda$ is an $H$-invariant family of
Lagrangian submanifold then under certain conditions we construct a form on
$\Lambda$ that descends to a closed form on $\Lambda/H.$ Integrating the latter
form over a cycle in $\Lambda/H$ we obtain numbers that can have interesting
physical meaning. We show that one can get string amplitudes this way. Applying
this construction to topological quantum field theories one obtains topological
invariants.Comment: 25 pages, typos corrected, explanations adde
The Energy Distribution of Subjets and the Jet Shape

We present a framework that describes the energy distribution of subjets of
radius $r$ within a jet of radius $R$. We consider both an inclusive sample of
subjets as well as subjets centered around a predetermined axis, from which the
jet shape can be obtained. For $r \ll R$ we factorize the physics at angular
scales $r$ and $R$ to resum the logarithms of $r/R$. For central subjets, we
consider both the standard jet axis and the winner-take-all axis, which involve
double and single logarithms of $r/R$, respectively. All relevant one-loop
matching coefficients are given, and an inconsistency in some previous results
for cone jets is resolved. Our results for the standard jet shape differ from
previous calculations at next-to-leading logarithmic order, because we account
for the recoil of the standard jet axis due to soft radiation. Numerical
results are presented for an inclusive subjet sample for $pp \to {\rm jet}+X$
at next-to-leading order plus leading logarithmic order.Comment: 39 pages, 7 figures, v2: journal versio
Holography for field theory solitons

We extend a well-known D-brane construction of the AdS/dCFT correspondence to
non-abelian defects. We focus on the bulk side of the correspondence and show
that there exists a regime of parameters in which the low-energy description
consists of two approximately decoupled sectors. The two sectors are gravity in
the ambient spacetime, and a six-dimensional supersymmetric Yang-Mills theory.
The Yang-Mills theory is defined on a rigid AdS_4 x S^2 background and admits
sixteen supersymmetries. We also consider a one-parameter deformation that
gives rise to a family of Yang-Mills theories on asymptotically AdS_4 x S^2
spacetimes, which are invariant under eight supersymmetries. With future
holographic applications in mind, we analyze the vacuum structure and
perturbative spectrum of the Yang-Mills theory on AdS_4 x S^2, as well as
systems of BPS equations for finite-energy solitons. Finally, we demonstrate
that the classical Yang-Mills theory has a consistent truncation on the
two-sphere, resulting in maximally supersymmetric Yang-Mills on AdS_4.Comment: 78 pages plus appendices, 4 figures; v2: references added; v3: typos

Averaged Null Energy Condition from Causality

Unitary, Lorentz-invariant quantum field theories in flat spacetime obey
microcausality: commutators vanish at spacelike separation. For interacting
theories in more than two dimensions, we show that this implies that the
averaged null energy, $\int du T_{uu}$, must be positive. This non-local
operator appears in the operator product expansion of local operators in the
lightcone limit, and therefore contributes to $n$-point functions. We derive a
sum rule that isolates this contribution and is manifestly positive. The
argument also applies to certain higher spin operators other than the stress
tensor, generating an infinite family of new constraints of the form $\int du
X_{uuu\cdots u} \geq 0$. These lead to new inequalities for the coupling
constants of spinning operators in conformal field theory, which include as
special cases (but are generally stronger than) the existing constraints from
the lightcone bootstrap, deep inelastic scattering, conformal collider methods,
and relative entropy. We also comment on the relation to the recent derivation
of the averaged null energy condition from relative entropy, and suggest a more
general connection between causality and information-theoretic inequalities in
QFT.Comment: 31+8 page
Modular and duality properties of surface operators in N=2* gauge
  theories

We calculate the instanton partition function of the four-dimensional N=2*
SU(N) gauge theory in the presence of a generic surface operator, using
equivariant localization. By analyzing the constraints that arise from
S-duality, we show that the effective twisted superpotential, which governs the
infrared dynamics of the two-dimensional theory on the surface operator,
satisfies a modular anomaly equation. Exploiting the localization results, we
solve this equation in terms of elliptic and quasi-modular forms which resum
all non-perturbative corrections. We also show that our results, derived for
monodromy defects in the four-dimensional theory, match the effective twisted
superpotential describing the infrared properties of certain two-dimensional
sigma models coupled either to pure N=2 or to N=2* gauge theories.Comment: 51 pages, v3: references added, typos fixed, footnote added, some

Do non-relativistic neutrinos oscillate?

We study the question of whether oscillations between non-relativistic
neutrinos or between relativistic and non-relativistic neutrinos are possible.
The issues of neutrino production and propagation coherence and their impact on
the above question are discussed in detail. It is demonstrated that no neutrino
oscillations can occur when neutrinos that are non-relativistic in the
laboratory frame are involved, except in a strongly mass-degenerate case. We
also discuss how this analysis depends on the choice of the Lorentz frame. Our
results are for the most part in agreement with Hinchliffe's rule.Comment: LaTeX, 22 pages. V2: typos corrected; minor textual changes. V3: sec.

Fivebranes and 3-manifold homology

Motivated by physical constructions of homological knot invariants, we study
their analogs for closed 3-manifolds. We show that fivebrane compactifications
provide a universal description of various old and new homological invariants
of 3-manifolds. In terms of 3d/3d correspondence, such invariants are given by
the Q-cohomology of the Hilbert space of partially topologically twisted 3d N=2
theory T[M_3] on a Riemann surface with defects. We demonstrate this by
concrete and explicit calculations in the case of monopole/Heegaard Floer
homology and a 3-manifold analog of Khovanov-Rozansky link homology. The latter
gives a categorification of Chern-Simons partition function. Some of the new
key elements include the explicit form of the S-transform and a novel
connection between categorification and a previously mysterious role of Eichler
integrals in Chern-Simons theory.Comment: 85 pages, 14 figure
Point-Particle Effective Field Theory II: Relativistic Effects and
  Coulomb/Inverse-Square Competition

We apply point-particle effective field theory (PPEFT) to compute the leading
shifts due to finite-size source effects in the Coulomb bound energy levels of
a relativistic spinless charged particle. This is the analogue for spinless
electrons of the contribution of the charge-radius of the source to these
levels, and we disagree with standard calculations in several ways. Most
notably we find there are two effective interactions with the same dimension
that contribute to leading order in the nuclear size. One is the standard
charge-radius contribution, while the other is a contact interaction whose
leading contribution to $\delta E$ arises linearly in the small length scale,
$\epsilon$, characterizing the finite-size effects, and is suppressed by
$(Z\alpha)^5$. We argue that standard calculations miss the contributions of
this second operator because they err in their choice of boundary conditions at
the source for the wave-function of the orbiting particle. PPEFT predicts how
this boundary condition depends on the source's charge radius, as well as on
the orbiting particle's mass. Its contribution turns out to be crucial if the
charge radius satisfies $\epsilon \lesssim (Z\alpha)^2 a_B$, with $a_B$ the
Bohr radius, since then relativistic effects become important. We show how the
problem is equivalent to solving the Schr\"odinger equation with competing
Coulomb, inverse-square and delta-function potentials, which we solve
explicitly. A similar enhancement is not predicted for the hyperfine structure,
due to its spin-dependence. We show how the charge-radius effectively runs due
to classical renormalization effects, and why the resulting RG flow is central
to predicting the size of the energy shifts. We discuss how this flow is
relevant to systems having much larger-than-geometric cross sections, and the
possible relevance to catalysis of reactions through scattering with monopoles.Comment: LaTeX, 22 pages plus appendices, v3: revised appendices, made more

Intersecting Surface Defects and Instanton Partition Functions

We analyze intersecting surface defects inserted in interacting
four-dimensional N = 2 supersymmetric quantum field theories. We employ the
realization of a class of such systems as the infrared fixed points of
renormalization group flows from larger theories, triggered by perturbed
Seiberg-Witten monopole-like configurations, to compute their partition
functions. These results are cast into the form of a partition function of
4d/2d/0d coupled systems. Our computations provide concrete expressions for the
instanton partition function in the presence of intersecting defects and we
study the corresponding ADHM model.Comment: 66 pages; v2: minor typos correcte
Effective Action for Non-Geometric Fluxes from Duality Covariant Actions

The (heterotic) double field theories and the exceptional field theories are
recently developed for manifestly duality covariant formulation of various
supergravity theories, describing low-energy limit of various (heterotic)
superstring and M-theory compactifications. These field theories are known to
be reduced to the standard descriptions by introducing appropriately
parameterized generalized metric and by applying suitably chosen section
conditions. We generalize this development to non-geometric backgrounds by
utilizing dual fields pertinent to non-geometric fluxes. We introduce different
parameterizations for the generalized metric, in terms of the conventional
supergravity fields or the dual fields. Under certain simplifying assumptions,
we construct new effective action for non-geometric backgrounds. We then obtain
the non-geometric backgrounds sourced by exotic branes. From them, we construct
their $U$-duality monodromy matrices. The charge of exotic branes obtained from
these monodromy matrices agrees perfectly with the charge obtained from the
non-geometric flux integral.Comment: cover + 101 pages; v2. published version in JHE
Anyons in Geometric Models of Matter

We show that the "geometric models of matter" approach proposed by the first
author can be used to construct models of anyon quasiparticles with fractional
quantum numbers, using 4-dimensional edge-cone orbifold geometries with
orbifold singularities along embedded 2-dimensional surfaces. The anyon states
arise through the braid representation of surface braids wrapped around the
orbifold singularities, coming from multisections of the orbifold normal bundle
of the embedded surface. We show that the resulting braid representations can
give rise to a universal quantum computer.Comment: 22 pages LaTe
