Bootstrapping the O(N) Archipelago

We study 3d CFTs with an $O(N)$ global symmetry using the conformal bootstrap
for a system of mixed correlators. Specifically, we consider all nonvanishing
scalar four-point functions containing the lowest dimension $O(N)$ vector
$\phi_i$ and the lowest dimension $O(N)$ singlet $s$, assumed to be the only
relevant operators in their symmetry representations. The constraints of
crossing symmetry and unitarity for these four-point functions force the
scaling dimensions $(\Delta_\phi, \Delta_s)$ to lie inside small islands. We
also make rigorous determinations of current two-point functions in the $O(2)$
and $O(3)$ models, with applications to transport in condensed matter systems.Comment: 32 pages, 13 figures; updated Fig.2, added references and minor

On Dunkl angular momenta algebra

We consider the quantum angular momentum generators, deformed by means of the
Dunkl operators. Together with the reflection operators they generate a
subalgebra in the rational Cherednik algebra associated with a finite real
reflection group. We find all the defining relations of the algebra, which
appear to be quadratic, and we show that the algebra is of
Poincare-Birkhoff-Witt (PBW) type. We show that this algebra contains the
angular part of the Calogero-Moser Hamiltonian and that together with constants
it generates the centre of the algebra. We also consider the gl(N) version of
the subalgebra of the rational Cherednik algebra and show that it is a
non-homogeneous quadratic algebra of PBW type as well. In this case the central
generator can be identified with the usual Calogero-Moser Hamiltonian
associated with the Coxeter group in the harmonic confinement.Comment: 27 pages; small changes, concluding remarks expande
Simplified SIMPs and the LHC

The existence of Dark Matter (DM) in the form of Strongly Interacting Massive
Particles (SIMPs) may be motivated by astrophysical observations that challenge
the classical Cold DM scenario. Other observations greatly constrain, but do
not completely exclude, the SIMP alternative. The signature of SIMPs at the LHC
may consist of neutral, hadron-like, trackless jets produced in pairs. We show
that the absence of charged content can provide a very efficient tool to
suppress dijet backgrounds at the LHC, thus enhancing the sensitivity to a
potential SIMP signal. We illustrate this using a simplified SIMP model and
present a detailed feasibility study based on simulations, including a
dedicated detector response parametrization. We evaluate the expected
sensitivity to various signal scenarios and tentatively consider the exclusion
limits on the SIMP elastic cross section with nucleons.Comment: 18 pages, 7 figure
Segmented Strings in $AdS_3$

We study segmented strings in flat space and in $AdS_3$. In flat space, these
well known classical motions describe strings which at any instant of time are
piecewise linear. In $AdS_3$, the worldsheet is composed of faces each of which
is a region bounded by null geodesics in an $AdS_2$ subspace of $AdS_3$. The
time evolution can be described by specifying the null geodesic motion of kinks
in the string at which two segments are joined. The outcome of collisions of
kinks on the worldsheet can be worked out essentially using considerations of
causality. We study several examples of closed segmented strings in $AdS_3$ and
find an unexpected quasi-periodic behavior. We also work out a WKB analysis of
quantum states of yo-yo strings in $AdS_3$ and find a logarithmic term
reminiscent of the logarithmic twist of string states on the leading Regge
trajectory.Comment: 38 pages, 5 figure
Non-Hermitian extension of gauge theories and implications for neutrino
  physics

An extension of QED is considered in which the Dirac fermion has both
Hermitian and anti-Hermitian mass terms, as well as both vector and
axial-vector couplings to the gauge field. Gauge invariance is restored when
the Hermitian and anti-Hermitian masses are of equal magnitude, and the theory
reduces to that of a single massless Weyl fermion. An analogous non-Hermitian
Yukawa theory is considered, and it is shown that this model can explain the
smallness of the light-neutrino masses and provide an additional source of
leptonic CP violation.Comment: 23 pages, 1 figure, JHEP style; corrections to match published

Supersymmetric D3/D7 for holographic flavors on curved space

We derive a new class of supersymmetric D3/D7 brane configurations, which
allow to holographically describe N=4 SYM coupled to massive N=2 flavor degrees
of freedom on spaces of constant curvature. We systematically solve the
$\kappa$-symmetry condition for D7-brane embeddings into AdS$_4$-sliced
AdS$_5\times$S$^5$, and find supersymmetric embeddings in a simple closed form.
Up to a critical mass, these embeddings come in surprisingly diverse families,
and we present a first study of their (holographic) phenomenology. We carry out
the holographic renormalization, compute the one-point functions and attempt a
field-theoretic interpretation of the different families. To complete the
catalog of supersymmetric D3/D7 configurations, we construct analogous
embeddings for flavored N=4 SYM on S$^4$ and dS$_4$.Comment: 37 pages, 9 figure
A Lorentz Covariant Holoraumy-Induced "Gadget" From Minimal Off-Shell
  4D, N = 1 Supermultiplets

Starting from three minimal off-shell 4D, $\cal N$ = 1 supermultiplets, using
constructions solely defined within the confines of the four dimensional field
theory we show the existence of a "gadget" - a member of a class of metrics on
the representation space of the supermultiplets - whose values directly and
completely correspond to the values of a metric defined on the 1d, $N$ = 4
adinkra networks adjacency matrices corresponding to the projections of the
four dimensional supermultiplets.Comment: LaTeX twice, 4 figures, 17 pp
Shift Symmetry and Higgs Inflation in Supergravity with Observable
  Gravitational Waves

We demonstrate how to realize within supergravity a novel chaotic-type
inflationary scenario driven by the radial parts of a conjugate pair of Higgs
superfields causing the spontaneous breaking of a grand unified gauge symmetry
at a scale assuming the value of the supersymmetric grand unification scale.
The superpotential is uniquely determined at the renormalizable level by the
gauge symmetry and a continuous R symmetry. We select two types of Kahler
potentials, which respect these symmetries as well as an approximate shift
symmetry. In particular, they include in a logarithm a dominant shift-symmetric
term proportional to a parameter c- together with a small term violating this
symmetry and characterized by a parameter c+. In both cases, imposing a lower
bound on c-, inflation can be attained with subplanckian values of the original
inflaton, while the corresponding effective theory respects perturbative
unitarity for r+-=c+/c-<1. These inflationary models do not lead to
overproduction of cosmic defects, are largely independent of the one-loop
radiative corrections and accommodate, for natural values of r+-, observable
gravitational waves consistently with all the current observational data. The
inflaton mass is mostly confined in the range (3.7-8.1)x10^10 GeV.Comment: Final version with some typos correcte
The Phase Diagram of Scalar Field Theory on the Fuzzy Disc

Using a recently developed bootstrapping method, we compute the phase diagram
of scalar field theory on the fuzzy disc with quartic even potential. We find
three distinct phases with second and third order phase transitions between
them. In particular, we find that the second order phase transition happens
approximately at a fixed ratio of the two coupling constants defining the
potential. We compute this ratio analytically in the limit of large coupling
constants. Our results qualitatively agree with previously obtained numerical
results.Comment: 1+17 pages, v2: typos fixed, published versio
All supersymmetric solutions of 3D U(1)$^3$ gauged supergravity

D3-branes wrapping constant curvature Riemann surfaces give rise to 2D N =
(0,2) SCFTs, where the superconformal fixed-points are mapped to vacua of 3D N
=2 U(1)^3 gauged supergravity. In this work we determine the fermionic
supersymmetry variations of the theory and present all supersymmetric
solutions. For spacetimes with a timelike Killing vector, we identify new
timelike warped AdS_3 (G\"odel) and timelike warped dS_3 critical points. We
outline the construction of numerical solutions interpolating between
fixed-points, demonstrate that these flows are driven by an irrelevant scalar
operator in the SCFT and identify the inverse of the superpotential as a
candidate c-function. We further classify all spacetimes with a null Killing
vector, in the process producing loci in parameter space where null-warped
AdS_3 vacua with Schrodinger z=2 symmetry exist. We construct
non-supersymmetric spacelike warped AdS_3 geometries based on D3-branes.Comment: 28 pages, 6 figures; v2 32 pages, 6 figures, references added,

Strong Coupling Running, Gauge Coupling Unification and the Scale of New
  Physics

The apparent unification of gauge couplings in Grand Unified Theories around
10$^{16}$ GeV is one of the strong arguments in favor of Supersymmetric
extensions of the Standard Model. In this paper, an analysis of the
measurements of the strong coupling running from the CMS experiment at the LHC
is combined with a "traditional" gauge coupling unification analysis using data
at the Z peak. This approach places powerful constraints on the possible scales
of new physics and on the parameters around the unification scale. A
supersymmetric analysis without GUT threshold corrections describes the CMS
data well and provides perfect unification. The favored scales are $M_{SUSY}\
=\ 2820\ +670\ -540$ GeV and $M_{GUT}\ =\ 1.05 \pm 0.06 \cdot 10^{16}$ GeV. For
zero or small threshold corrections the scale of new physics may be well within
LHC reach.Comment: 11 pages, 4 figures, 2 table
A Dynamic Modification to Sneutrino Chaotic Inflation

We consider a right-handed scalar neutrino as the inflaton which carries a
gravitational coupling with a supersymmetric QCD sector responsible for
breaking supersymmetry dynamically. The framework suggests an inflaton
potential which is a deformed version of the quadratic chaotic inflation
leading to a flatter potential. We find that this deformation results a sizable
tensor to scalar ratio which falls within the allowed region by PLANCK 2015. At
the same time supersymmetry breaking at the end of inflation can naturally be
induced in this set-up. The symmetries required to construct the framework
allows the neutrino masses and mixing to be of right order.Comment: 24 pages, 3 figures; version to appear in JHE
T-dualization in a curved background in absence of a global symmetry

We investigate T-duality of a closed string moving in a weakly curved
background of the second order. A previously discussed weakly curved background
consisted of a flat metric and a linearly coordinate dependent Kalb-Ramond
field with an infinitesimal strength. The background here considered differs
from the above in a coordinate dependent metric of the second order.
Consequently, the corresponding Ricci tensor is nonzero. As this background
does not posses the global shift symmetry the generalized Buscher T-dualization
procedure is not applicable to it. We redefine it and make it applicable to
backgrounds without the global symmetry
Charm in Deep-Inelastic Scattering

We show how to extend systematically the FONLL scheme for inclusion of heavy
quark mass effects in DIS to account for the possible effects of an intrinsic
charm component in the nucleon. We show that when there is no intrinsic charm,
FONLL is equivalent to S-ACOT to any order in perturbation theory, while when
an intrinsic charm component is included FONLL is identical to ACOT, again to
all orders in perturbation theory. We discuss in detail the inclusion of top
and bottom quarks to construct a variable flavour number scheme, and give
explicit expressions for the construction of the structure functions $F^c_2$,
$F^c_L$ and $F^c_3$ to NNLO.Comment: 43 pages, 1 figure. Final JHEP versio
Geometric Engineering, Mirror Symmetry and 6d (1,0) -> 4d, N=2

We study compactification of 6 dimensional (1,0) theories on T^2. We use
geometric engineering of these theories via F-theory and employ mirror symmetry
technology to solve for the effective 4d N=2 geometry for a large number of the
(1,0) theories including those associated with conformal matter. Using this we
show that for a given 6d theory we can obtain many inequivalent 4d N=2 SCFTs.
Some of these respect the global symmetries of the 6d theory while others
exhibit SL(2,Z) duality symmetry inherited from global diffeomorphisms of the
T^2. This construction also explains the 6d origin of moduli space of 4d affine
ADE quiver theories as flat ADE connections on T^2. Among the resulting 4d N=2
CFTs we find theories whose vacuum geometry is captured by an LG theory (as
opposed to a curve or a local CY geometry). We obtain arbitrary genus curves of
class S with punctures from toroidal compactification of (1,0) SCFTs where the
curve of the class S theory emerges through mirror symmetry. We also show that
toroidal compactification of the little string version of these theories can
lead to class S theories with no punctures on arbitrary genus Riemann surface.Comment: 58 pages, 8 figures, v2: references added, typos fixed, table 2

Heavy Higgs Bosons at 14 TeV and 100 TeV

Searching for Higgs bosons beyond the Standard Model (BSM) is one of the most
important missions for hadron colliders. As a landmark of BSM physics, the MSSM
Higgs sector at the LHC is expected to be tested up to the scale of the
decoupling limit of O(1) TeV, except for a wedge region centered around
$\tan\beta \sim 3 -10$, which has been known to be difficult to probe. In this
article, we present a dedicated study testing the decoupled MSSM Higgs sector,
at the LHC and a next-generation $pp$-collider, proposing to search in channels
with associated Higgs productions, with the neutral and charged Higgs further
decaying into $tt$ and $tb$, respectively. In the case of neutral Higgs we are
able to probe for the so far uncovered wedge region via $pp\to bb H/A \to
bbtt$. Additionally, we cover the the high $\tan\beta$ range with $pp\to bb H/A
\to bb\tau\tau$. The combination of these searches with channels dedicated to
the low $\tan\beta$ region, such as $pp\to H/A \to tt$ and $pp\to tt H/A \to
tttt$ potentially covers the full $\tan\beta$ range. The search for charged
Higgs has a slightly smaller sensitivity for the moderate $\tan\beta$ region,
but additionally probes for the higher and lower $\tan\beta$ regions with even
greater sensitivity, via $pp\to tb H^\pm \to tbtb$. While the LHC will be able
to probe the whole $\tan\beta$ range for Higgs masses of O(1) TeV by combining
these channels, we show that a future 100 TeV $pp$-collider has a potential to
push the sensitivity reach up to $\sim \mathcal O(10)$ TeV. In order to deal
with the novel kinematics of top quarks produced by heavy Higgs decays, the
multivariate Boosted Decision Tree (BDT) method is applied in our collider
analyses. The BDT-based tagging efficiencies of both hadronic and leptonic
top-jets, and their mutual fake rates as well as the faking rates by other jets
($h$, $Z$, $W$, $b$, etc.) are also presented.Comment: published versio
General squark flavour mixing: constraints, phenomenology and benchmarks

We present an extensive study of non-minimal flavour violation in the squark
sector in the framework of the Minimal Supersymmetric Standard Model. We
investigate the effects of multiple non-vanishing flavour-violating elements in
the squark mass matrices by means of a Markov Chain Monte Carlo scanning
technique and identify parameter combinations that are favoured by both current
data and theoretical constraints. We then detail the resulting distributions of
the flavour-conserving and flavour-violating model parameters. Based on this
analysis, we propose a set of benchmark scenarios relevant for future studies
of non-minimal flavour violation in the Minimal Supersymmetric Standard Model.Comment: 31 pages, 12 figures, 6 tables; SLHA files for non-minimally

Wormhole and Entanglement (Non-)Detection in the ER=EPR Correspondence

The recently proposed ER=EPR correspondence postulates the existence of
wormholes (Einstein-Rosen bridges) between entangled states (such as EPR
pairs). Entanglement is famously known to be unobservable in quantum mechanics,
in that there exists no observable (or, equivalently, projector) that can
accurately pick out whether a generic state is entangled. Many features of the
geometry of spacetime, however, are observables, so one might worry that the
presence or absence of a wormhole could identify an entangled state in ER=EPR,
violating quantum mechanics, specifically, the property of state-independence
of observables. In this note, we establish that this cannot occur: there is no
measurement in general relativity that unambiguously detects the presence of a
generic wormhole geometry. This statement is the ER=EPR dual of the
undetectability of entanglement.Comment: 14 pages, 4 figure
Higgsophilic gauge bosons and monojets at the LHC

We consider a generic framework where the Standard Model (SM) coexists with a
hidden sector endowed with some additional gauge symmetry. When this symmetry
is broken by a scalar field charged under the hidden gauge group, the
corresponding scalar boson generally mixes with the SM Higgs boson. In
addition, massive hidden gauge bosons emerge and via the mixing, the observed
Higgs-like mass eigenstate is the only known particle that couples to these
hidden gauge bosons directly.
  We study the LHC monojet signatures of this scenario and the corresponding
constraints on the gauge coupling of the hidden gauge group as well as the
mixing of the Higgs scalars.Comment: 18 pages, 4 figure
Warped Weyl fermion partition functions

Warped conformal field theories (WCFTs) are a novel class of non-relativistic
theories. A simple, yet non-trivial, example of such theory is a massive Weyl
fermion in $(1+1)$-dimensions, which we study in detail. We derive general
properties of the spectrum and modular properties of partition functions of
WCFTs. The periodic (Ramond) sector of this fermionic system is non-trivial,
and we build two novel partition functions for this sector which have no
counterpart in a CFT$_2$. The thermodynamical properties of WCFTs are revisited
in the canonical and micro-canonical ensemble.Comment: 41 page
Effective actions in ${\cal N}$=1, D5 supersymmetric gauge theories:
  harmonic superspace approach

We consider the off-shell formulation of the 5D, $ {\cal N}$=1 super
Yang-Mills and super Chern-Simons theories in harmonic superspace. Using such a
formulation we develop a manifestly supersymmetric and gauge invariant approach
to constructing the one-loop effective action both in super Yang-Mills and
super Chern-Simons models. On the base of this approach we compute the leading
low-energy quantum contribution to the effective action on the Abelian vector
multiplet background. This contribution corresponds to $F^4$ invariant which is
given in 5D superfield form.Comment: 29 pages, minor modification, published versio
$\mathbf{O}(D,D)$ Covariant Noether Currents and Global Charges in
  Double Field Theory

Double field theory is an approach for massless modes of string theory,
unifying and geometrizing all gauge invariance in manifest $\mathbf{O}(D,D)$
covariant manner. In this approach, we derive off-shell conserved Noether
current and corresponding Noether potential associated with unified gauge
invariance. We add Wald-type counter two-form to the Noether potential and
define conserved global charges as surface integral. We check our
$\mathbf{O}(D,D)$ covariant formula against various string backgrounds, both
geometric and non-geometric. In all cases we examined, we find perfect
agreements with previous results. Our formula facilitates to evaluate momenta
along not only ordinary spacetime directions but also dual spacetime directions
on equal footing. From this, we confirm recent assertion that null wave in
doubled spacetime is the same as macroscopic fundamental string in ordinary
spacetime.Comment: v2) 1+42 pages, Refs added, minor changes. To appear in JHE
Hedgehog Bases for A_n Cluster Polylogarithms and An Application to
  Six-Point Amplitudes

Multi-loop scattering amplitudes in N=4 Yang-Mills theory possess cluster
algebra structure. In order to develop a computational framework which exploits
this connection, we show how to construct bases of Goncharov polylogarithm
functions, at any weight, whose symbol alphabet consists of cluster coordinates
on the $A_n$ cluster algebra. Using such a basis we present a new expression
for the 2-loop 6-particle NMHV amplitude which makes some of its cluster
structure manifest.Comment: 32 pages; v2: minor corrections and clarification
Features of electroweak symmetry breaking in five dimensional SUSY
  models

We explore the phenomenological predictions of a supersymmetric standard
model, with a large extra dimension and unifying gauge couplings. The modified
five dimensional renormalisation group equations make it possible to obtain
light, maximally mixed stops, with a low scale of supersymmetry breaking and a
low unification scale. This allows the fine-tuning to be lowered right down to
the barrier coming directly from experimental lower limits on the stop masses.
We also show that attempts at modifying the SUSY breaking pattern to obtain
more natural soft terms at the high scale do not give the expected fine-tuning
relaxation, and only RGE effects turn out to be effective in generating a lower
fine-tuning
Form factors of B, Bs -> eta, eta' and D, Ds -> eta, eta' transitions
  from QCD light-cone sum rules

In the framework of the QCD light-cone sum rules (LCSRs) we present the
analysis of all $B, B_{s}\to \eta^{(\prime)}$ and $D, D_{s}\to \eta^{(\prime)}$
form factors ($f^+, f^0$ and $f^T$) by including $m_{\eta^{(\prime)}}^2$
corrections in the leading (up to the twist-four) and next-to-leading order (up
to the twist-three) in QCD, and two-gluon contributions to the form factors at
the leading twist. The SU(3)-flavour breaking corrections and the axial anomaly
contributions to the distribution amplitudes are also consistently taken into
account. The complete results for the $f^0$ and $f^T$ form factors of $B,B_s
\to \eta^{(\prime)}$ and $D, D_{s} \to \eta^{(\prime)}$ relevant for processes
like $B \to \eta^{(\prime)} \tau \nu_{\tau}$ or $B_{s} \to \eta^{(\prime)} l^+

0.212^{+0.015}_{-0.013}$, $f^+_{B\eta^\prime}(0)= 0.130^{+0.036}_{-0.032}$,
