ODE/IM correspondence and the Argyres-Douglas theory

We study the quantum spectral curve of the Argyres-Douglas theories in the
Nekrasov-Sahashvili limit of the Omega-background. Using the ODE/IM
correspondence we investigate the quantum integrable model corresponding to the
quantum spectral curve. We show that the models for the $A_{2N}$-type theories
are non-unitary coset models $(A_1)_1\times (A_1)_{L}/(A_1)_{L+1}$ at the
fractional level $L=\frac{2}{2N+1}-2$, which appear in the study of the 4d/2d
correspondence of ${\cal N}=2$ superconformal field theories. Based on the WKB
analysis, we clarify the relation between the Y-functions and the quantum
periods and study the exact Bohr-Sommerfeld quantization condition for the
quantum periods. We also discuss the quantum spectral curves for the D and E
type theories.Comment: 28 pages, 1 figure. Typos corrected, a reference is added. Published

Study of dark matter physics in non-universal gaugino mass scenario

We study dark matter physics in the Minimal Supersymmetric Standard Model
with non-universal gaugino masses at the unification scale. In this scenario,
the specific ratio of wino and gluino masses realizes the electro-weak scale
naturally and achieves 125 GeV Higgs boson mass. Then, relatively light
higgsino is predicted and the lightest neutral particle, that is dominantly
given by the neutral component of higgsino, is a good dark matter candidate.
The direct detection of the dark matter is sensitive to not only a higgsino
mass but also gaugino masses significantly. The upcoming XENON1T experiment
excludes the parameter region where bino or gluino is lighter than about 2.5
TeV if the higgsino and the gaugino mass parameters have same signs. We see
that the direct detection of dark matter gives stronger bound than the direct
search at the LHC experiment when higgsino sizably contributes to the dark
matter abundanceComment: 21 pages, 5 figures, 1 tabl
Setting limits on Effective Field Theories: the case of Dark Matter

The usage of Effective Field Theories (EFT) for LHC new physics searches is
receiving increasing attention. It is thus important to clarify all the aspects
related with the applicability of the EFT formalism in the LHC environment,
where the large available energy can produce reactions that overcome the
maximal range of validity, i.e. the cutoff, of the theory. We show that this
does forbid to set rigorous limits on the EFT parameter space through a
modified version of the ordinary binned likelihood hypothesis test, which we
design and validate. Our limit-setting strategy can be carried on in its
full-fledged form by the LHC experimental collaborations, or performed
externally to the collaborations, through the Simplified Likelihood approach,
by relying on certain approximations. We apply it to the recent CMS mono-jet
analysis and derive limits on a Dark Matter (DM) EFT model. DM is selected as a
case study because the limited reach on the DM production EFT Wilson
coefficient and the structure of the theory suggests that the cutoff might be
dangerously low, well within the LHC reach. However our strategy can also be
applied to EFT's parametrising the indirect effects of heavy new physics in the
Electroweak and Higgs sectors
2D CFT Partition Functions at Late Times

We consider the late time behavior of the analytically continued partition
function $Z(\beta + it) Z(\beta - it)$ in holographic $2d$ CFTs. This is a
probe of information loss in such theories and in their holographic duals. We
show that each Virasoro character decays in time, and so information is not
restored at the level of individual characters. We identify a universal
decaying contribution at late times, and conjecture that it describes the
behavior of generic chaotic $2d$ CFTs out to times that are exponentially large
in the central charge. It was recently suggested that at sufficiently late
times one expects a crossover to random matrix behavior. We estimate an upper
bound on the crossover time, which suggests that the decay is followed by a
parametrically long period of late time growth. Finally, we discuss integrable
theories and show how information is restored at late times by a series of
characters. This hints at a possible bulk mechanism, where information is
restored by an infinite sum over non-perturbative saddles.Comment: 36 pages, 7 figure
Triggering Soft Bombs at the LHC

Very high multiplicity, spherically-symmetric distributions of soft
particles, with $p_T$ ~ few hundred MeV, may be a signature of strongly-coupled
hidden valleys that exhibit long, efficient showering windows. With traditional
triggers, such "soft bomb" events closely resemble pile-up and are therefore
only recorded with minimum bias triggers at a very low efficiency. We
demonstrate a proof-of-concept for a high-level triggering strategy that
efficiently separates soft bombs from pile-up by searching for a "belt of
fire": A high density band of hits on the innermost layer of the tracker.
Seeding our proposed high-level trigger with existing jet, missing transverse
energy or lepton hardware-level triggers, we show that net trigger efficiencies
of order 10% are possible for bombs of mass several hundred GeV. We also
consider the special case that soft bombs are the result of an exotic decay of
the 125 GeV Higgs. The fiducial rate for "Higgs bombs" triggered in this manner
is marginally higher than the rate achievable by triggering directly on a hard
muon from associated Higgs production.Comment: 38 pages, 5 tables, 14 figure
Phenomenology of ELDER Dark Matter

We explore the phenomenology of Elastically Decoupling Relic (ELDER) dark
matter. ELDER is a thermal relic whose present density is determined primarily
by the cross-section of its elastic scattering off Standard Model (SM)
particles. Assuming that this scattering is mediated by a kinetically mixed
dark photon, we argue that the ELDER scenario makes robust predictions for
electron-recoil direct-detection experiments, as well as for dark photon
searches. These predictions are independent of the details of interactions
within the dark sector. Together with the closely related Strongly-Interacting
Massive Particle (SIMP) scenario, the ELDER predictions provide a physically
motivated, well-defined target region, which will be almost entirely accessible
to the next generation of searches for sub-GeV dark matter and dark photons. We
provide useful analytic approximations for various quantities of interest in
the ELDER scenario, and discuss two simple renormalizable toy models which
incorporate the required strong number-changing interactions among the ELDERs,
as well as explicitly implement the coupling to electrons via the dark photon
portal.Comment: 31 pages, 6 figures, minor corrections, updates to match version

More Toda-like (0,2) mirrors

In this paper, we extend our previous work to construct (0,2) Toda-like
mirrors to A/2-twisted theories on more general spaces, as part of a program of
understanding (0,2) mirror symmetry. Specifically, we propose (0,2) mirrors to
GLSMs on toric del Pezzo surfaces and Hirzebruch surfaces with deformations of
the tangent bundle. We check the results by comparing correlation functions,
global symmetries, as well as geometric blowdowns with the corresponding (0,2)
Toda-like mirrors. We also briefly discuss Grassmannian manifolds.Comment: 49 pages, LaTeX; v2: references adde
Intertwined Orders in Holography: Pair and Charge Density Waves

Building on [1], we examine a holographic model in which a U(1) symmetry and
translational invariance are broken spontaneously at the same time. The
symmetry breaking is realized through the St\"{u}ckelberg mechanism, and leads
to a scalar condensate and a charge density which are spatially modulated and
exhibit unidirectional stripe order. Depending on the choice of parameters, the
oscillations of the scalar condensate can average out to zero, with a frequency
which is half of that of the charge density. In this case the system realizes
some of the key features of pair density wave order. The model also admits a
phase with co-existing superconducting and charge density wave orders, in which
the scalar condensate has a uniform component. In our construction the various
orders are intertwined with each other and have a common origin. The fully
backreacted geometry is computed numerically, including for the case in which
the theory contains axions. The latter can be added to explicitly break
translational symmetry and mimic lattice-type effects.Comment: 37 pages, 17 figure
SYK-like Tensor Models on the Lattice

We study large $N$ tensor models on the lattice without disorder. We
introduce techniques which can be applied to a wide class of models, and
illustrate it by studying some specific rank-3 tensor models. In particular, we
study Klebanov-Tarnopolsky model on lattice, Gurau-Witten model (by treating it
as a tensor model on four sites) and also a new model which interpolates
between these two models. In each model, we evaluate various four point
functions at large $N$ and strong coupling, and discuss their spectrum and long
time behaviors. We find similarities as well as differences from SYK model. We
also generalize our analysis to rank-$D$ tensor models where we obtain
analogous results as $D=3$ case for the four point functions which we computed.
For $D>5$, we are able to compute the next-to-subleading ${1 \over N}$
corrections for a specific four point function.Comment: 46 pages, 29 figures; v2:typos corrected, reference added; v3:minor

Black holes from CFT: Universality of correlators at large c

Two-dimensional conformal field theories at large central charge and with a
sufficiently sparse spectrum of light states have been shown to exhibit
universal thermodynamics. This thermodynamics matches that of AdS$_3$ gravity,
with a Hawking-Page transition between thermal AdS and the BTZ black hole. We
extend these results to correlation functions of light operators. Upon making
some additional assumptions, such as large $c$ factorization of correlators, we
establish that the thermal AdS and BTZ solutions emerge as the universal
backgrounds for the computation of correlators. In particular, Witten diagrams
computed on these backgrounds yield the CFT correlators, order by order in a
large $c$ expansion, with exponentially small corrections. In pure CFT terms,
our result is that thermal correlators of light operators are determined
entirely by light spectrum data. Our analysis is based on the constraints of
modular invariance applied to the torus two-point function.Comment: 18 pages. v2: minor edit
Unity of pomerons from gauge/string duality

We develop a formalism where the hard and soft pomeron contributions to high
energy scattering arise as leading Regge poles of a single kernel in
holographic QCD. The kernel is obtained using effective field theory inspired
by Regge theory of a 5-d string theory. It describes the exchange of higher
spin fields in the graviton Regge trajectory that are dual to glueball states
of twist two. For a specific holographic QCD model we describe Deep Inelastic
Scattering in the Regge limit of low Bjorken x, finding good agreement with
experimental data from HERA. The observed rise of the effective pomeron
intercept, as the size of the probe decreases, is reproduced by considering the
first four pomeron trajectories. In the case of soft probes, relevant to total
cross sections, the leading hard pomeron trajectory is suppressed, such that in
this kinematical region we reproduce an intercept of 1.09 compatible with the
QCD soft pomeron data. In the spectral region of positive Maldelstam variable t
the first two pomeron trajectories are consistent with current expectations for
the glueball spectrum from lattice simulations
Horizon fluff, semi-classical black hole microstates - Log-corrections
  to BTZ entropy and black hole/particle correspondence

According to the horizon fluff proposal microstates of a generic black hole
belong to a certain subset of near horizon soft hairs that cannot be extended
beyond the near horizon region. In [1,2] it was shown how the horizon fluff
proposal works for AdS3 black holes. In this work we clarify further this
picture by showing that BTZ black hole microstates are in general among the
coherent states in the Hilbert space associated with conic spaces or their
Virasoro descendants, provided we impose a (Bohr-type) quantization condition
on the angular deficit. Thus BTZ black holes may be viewed as condensates (or
solitonic states) of AdS3 particles. We provide canonical and microcanonical
descriptions of the statistical mechanical system associated with BTZ black
holes and their microstates, and relate them. As a further non-trivial check we
show the horizon fluff proposal correctly reproduces the expected logarithmic
corrections to the BTZ entropy.Comment: 47pp, v2: added references, minor correction in section 6.1, results

NLO predictions for Higgs boson pair production with full top quark mass
  dependence matched to parton showers

We present the first combination of NLO QCD matrix elements for di-Higgs
production, retaining the full top quark mass dependence, with a parton shower.
Results are provided within both the POWHEG-BOX and MadGraph5_aMC@NLO Monte
Carlo frameworks. We assess in detail the theoretical uncertainties and provide
differential results. We find that, as expected, the shower effects are
relatively large for observables like the transverse momentum of the Higgs
boson pair, which are sensitive to extra radiation. However, these shower
effects are still much smaller than the differences between the Born-improved
HEFT approximation and the full NLO calculation in the tails of the
distributions.Comment: replaced by published version; in addition typos corrected in

Solving The Muon g-2 Anomaly With Natural NMSSM From Generalized
  Deflected AMSB

We propose to realize (natural) NMSSM spectrum from deflected AMSB with new
messenger-matter interactions. With additional messenger-matter interactions
involving ${\bf 10}\oplus{\bf \overline{10}}$ representation messengers, the
muon g-2 anomaly can be solved at $2\sigma$ (or $3\sigma$) level with the
corresponding gluino mass range $2.8~{\rm TeV}<m_{\tilde{g}}<5.4~ {\rm TeV}$
(or $2.6 ~{\rm TeV}<m_{\tilde{g}}<7.3~ {\rm TeV}$). Besides, our scenario is
fairly natural within which the involved fine tuning can be as low as 47. So,
in the framework of AMSB-type scenarios, NMSSM can be advantageous in
explaining the muon g-2 anomaly in compare with MSSM.Comment: 23 pages, 7 figure
$\mathcal{N}{=}1$ supersymmetric indices and the four-dimensional
  A-model

We compute the supersymmetric partition function of $\mathcal{N}{=}1$
supersymmetric gauge theories with an $R$-symmetry on $\mathcal{M}_4 \cong
\mathcal{M}_{g,p}\times S^1$, a principal elliptic fiber bundle of degree $p$
over a genus-$g$ Riemann surface, $\Sigma_g$. Equivalently, we compute the
generalized supersymmetric index $I_{\mathcal{M}_{g,p}}$, with the
supersymmetric three-manifold ${\mathcal{M}_{g,p}}$ as the spatial slice. The
ordinary $\mathcal{N}{=}1$ supersymmetric index on the round three-sphere is
recovered as a special case. We approach this computation from the point of
view of a topological $A$-model for the abelianized gauge fields on the base
$\Sigma_g$. This $A$-model---or $A$-twisted two-dimensional
$\mathcal{N}{=}(2,2)$ gauge theory---encodes all the information about the
generalized indices, which are viewed as expectations values of some
canonically-defined surface defects wrapped on $T^2$ inside $\Sigma_g \times
T^2$. Being defined by compactification on the torus, the $A$-model also enjoys
natural modular properties, governed by the four-dimensional 't Hooft
anomalies. As an application of our results, we provide new tests of Seiberg
duality. We also present a new evaluation formula for the three-sphere index as
a sum over two-dimensional vacua.Comment: 91 pages including appendices; v2: corrected typos and added

Rare radiative charm decays within the standard model and beyond

We present standard model (SM) estimates for exclusive $c \to u \gamma$
processes in heavy quark and hybrid frameworks. Measured branching ratios
${\cal{B}}(D^0 \to (\phi, \bar K^{*0}) \gamma)$ are at or somewhat exceeding
the upper range of the SM and suggest slow convergence of the $1/m_D,
\alpha_s$-expansion. Model-independent constraints on $|\Delta C|=|\Delta U|=1$
dipole operators from ${\cal{B}}(D^0 \to \rho^0 \gamma)$ data are obtained.
Predictions and implications for leptoquark models are worked out. While
branching ratios are SM-like CP asymmetries $\lesssim 10 \%$ can be induced. In
SUSY deviations from the SM can be even larger with CP asymmetries of $O(0.1)$.
If $\Lambda_c$-baryons are produced polarized, such as at the $Z$-pole, an
angular asymmetry in $\Lambda_c \to p \gamma$ decays can be studied that is
sensitive to chirality-flipped contributions.Comment: 23 pages plus references and appendices, 7 figures; v2:

Neutrino Masses and Absence of Flavor Changing Interactions in the 2HDM

We propose several Two Higgs Doublet Models with the addition of an Abelian
gauge group which free the usual framework from flavor changing neutral
interactions and explain neutrino masses through the seesaw mechanism. We
discuss the kinetic and mass-mixing gripping phenomenology which encompass
several constraints coming from atomic parity violation, the muon anomalous
magnetic moment, rare meson decays, Higgs physics, LEP precision data,
neutrino-electron scattering, low energy accelerators and LHC probes.Comment: 54 pages, 10 figure
Constraints on the relaxion mechanism with strongly interacting
  vector-fermions

We study the experimental constraints on strongly interacting vector-fermions
compatible with the relaxion mechanism and investigate any possible tuning. The
focus is on a minimal model and low confinement scale. More precisely, we study
bounds from electroweak precision tests, Higgs decay, Big Bang nucleosynthesis
and direct collider searches. The effect of these new fermions on vacuum
stability is also investigated. Combining our bounds, we show that the relaxion
mechanism becomes increasingly constrained and fine-tuned as the confinement
scale decreases. For example, a confinement scale of a few tens of MeVs would
require tuning at the percent level.Comment: 27 pages, 10 figures. References added. Matches published versio
Enlarging Regions of the MSSM Parameter Space for Large $\tan\beta$ via
  SUSY Decays of the Heavy Higgs Bosons

In the Minimal Supersymmetric Standard Model (MSSM) searches for the heaviest
CP-even and CP-odd Higgs $H$, $A$ to tau-lepton pairs severely constrain the
parameter region for large values of $\tan\beta$ and light Higgs bosons $H$,
$A$. We demonstrate how the experimental constraint can be avoided by new
decays to light third-generation sfermions, whose left-right couplings to $H$
can be maximised in regions of large trilinear couplings $A_{b}$, $A_{\tau}$
for sbottoms and staus, or large supersymmetric (SUSY) Higgs mass $\mu$ for
stops. Due to the $\tan\beta$-enhancement in the production cross-sections via
gluon-fusion and in association with bottom-quark pairs for $H$ and $A$, we
find that down-type sfermions, in particular, sbottoms perform a better job in
allowing more parameter space than up-type sfermions such as stops, which
require much larger values of $\mu$ to compensate for $\tan\beta$. Vacuum
stability as well as flavour observables constraints and direct searches for
SUSY particles are imposed. We also associate the lightest CP-even Higgs with
the observed 125 GeV SM-like Higgs and impose the experimental constraints from
the LHC.Comment: 16 pages, 6 figures. Final published versio
Non-resonant Collider Signatures of a Singlet-Driven Electroweak Phase
  Transition

We analyze the collider signatures of the real singlet extension of the
Standard Model in regions consistent with a strong first-order electroweak
phase transition and a singlet-like scalar heavier than the Standard Model-like
Higgs. A definitive correlation exists between the strength of the phase
transition and the trilinear coupling of the Higgs to two singlet-like scalars,
and hence between the phase transition and non-resonant scalar pair production
involving the singlet at colliders. We study the prospects for observing these
processes at the LHC and a future 100 TeV $pp$ collider, focusing particularly
on double singlet production. We also discuss correlations between the strength
of the electroweak phase transition and other observables at hadron and future
lepton colliders. Searches for non-resonant singlet-like scalar pair production
at 100 TeV would provide a sensitive probe of the electroweak phase transition
in this model, complementing resonant di-Higgs searches and precision
measurements. Our study illustrates a strategy for systematically exploring the
phenomenologically viable parameter space of this model, which we hope will be
useful for future work.Comment: 34 pages + 4 appendices, 13 figures. Comments welcome
Combinatorics and Topology of Kawai-Lewellen-Tye Relations

We revisit the relations between open and closed string scattering amplitudes
discovered by Kawai, Lewellen, and Tye (KLT). We show that they emerge from the
underlying algebro-topological identities known as the twisted period
relations. In order to do so, we formulate tree-level string theory amplitudes
in the language of twisted de Rham theory. There, open string amplitudes are
understood as pairings between twisted cycles and cocycles. Similarly, closed
string amplitudes are given as a pairing between two twisted cocycles. Finally,
objects relating the two types of string amplitudes are the $\alpha'$-corrected
bi-adjoint scalar amplitudes recently defined by the author [arXiv:1610.04230].
We show that they naturally arise as intersection numbers of twisted cycles. In
this work we focus on the combinatorial and topological description of twisted
cycles relevant for string theory amplitudes. In this setting, each twisted
cycle is a polytope, known in combinatorics as the associahedron, together with
an additional structure encoding monodromy properties of string integrals. In
fact, this additional structure is given by higher-dimensional generalizations
of the Pochhammer contour. An open string amplitude is then computed as an
integral of a logarithmic form over an associahedron. We show that the inverse
of the KLT kernel can be calculated from the knowledge of how pairs of
associahedra intersect one another in the moduli space. In the field theory
limit, contributions from these intersections localize to vertices of the
associahedra, giving rise to the bi-adjoint scalar partial amplitudes.Comment: 51 page
