Renormalization schemes for the Two-Higgs-Doublet Model and applications
  to h -> WW/ZZ -> 4fermions

We perform the renormalization of different types of Two-Higgs-Doublet Models
for the calculation of observables at next-to-leading order. In detail, we
suggest four different renormalization schemes based on on-shell
renormalization conditions as far as possible and on MSbar prescriptions for
the remaining field-mixing parameters where no distinguished on-shell condition
exists and make contact to existing schemes in the literature. In particular,
we treat the tadpole diagrams in different ways and discuss issues of gauge
independence and perturbative stability in the considered schemes. The
renormalization group equations for the MSbar parameters are solved in each
scheme, so that a consistent renormalization scale variation can be performed.
We have implemented all Feynman rules including counterterms and the
renormalization conditions into a FeynArts model file, so that amplitudes and
squared matrix elements can be generated automatically. As an application we
compute the decay of the light, CP-even Higgs boson of the Two-Higgs-Doublet
Model into four fermions at next-to-leading order. The comparison of different
schemes and the investigation of the renormalization scale dependence allows us
to test the perturbative consistency in each of the renormalization schemes,
and to get a better estimate of the theoretical uncertainty that arises due to
the truncation of the perturbation series.Comment: 44 pages, 8 figures, revised version, to appear in JHE
Dualities of Deformed $\mathcal{N=2}$ SCFTs from Link Monodromy on
  D3-brane States

We study D3-brane theories that are dually described as deformations of two
different $\mathcal{N}=2$ superconformal theories with massless monopoles and
dyons. These arise at the self-intersection of a seven-brane in F-theory, which
cuts out a link on a small three-sphere surrounding the self-intersection. The
spectrum is studied by taking small loops in the three-sphere, yielding a
link-induced monodromy action on string junction D3-brane states, and
subsequently quotienting by the monodromy. This reduces the differing flavor
algebras of the $\mathcal{N}=2$ theories to the same flavor algebra, as
required by duality, and projects out charged states, yielding an
$\mathcal{N}=1$ superconformal theory on the D3-brane. In one, a deformation of
a rank one Argyres-Douglas theory retains its $SU(2)$ flavor symmetry and
exhibits a charge neutral flavor triplet that is comprised of electron, dyon,
and monopole string junctions. From duality we argue that the monodromy
projection should also be imposed away from the conformal point, in which case
the D3-brane field theory appears to exhibit confinement of electrons, dyons,
and monopoles. We will address the mathematical counterparts in a companion
paper.Comment: 28+20 pages, 8 figures 6 table
Asymptotic Fragility, Near $AdS_2$ Holography and $T\bar{T}$

We present the exact solution for the scattering problem in the flat space
Jackiw-Teitelboim (JT) gravity coupled to an arbitrary quantum field theory. JT
gravity results in a gravitational dressing of field theoretical scattering
amplitudes. The exact expression for the dressed $S$-matrix was previously
known as a solvable example of a novel UV asymptotic behavior, dubbed
asymptotic fragility. This dressing is equivalent to the $T\bar{T}$ deformation
of the initial quantum field theory. JT gravity coupled to a single massless
boson provides a promising action formulation for an integrable approximation
to the worldsheet theory of confining strings in 3D gluodynamics. We also
derive the dressed $S$-matrix as a flat space limit of the near $AdS_2$
holography. We show that in order to preserve the flat space unitarity the
conventional Schwarzian dressing of boundary correlators needs to be slightly
extended. Finally, we propose a new simple expression for flat space amplitudes
of massive particles in terms of correlators of holographic CFT's.Comment: 39+7 pages; v2: notation clarified, typos corrected, references

$\theta=\pi$ in $SU(N)/\mathbb{Z}_N$ gauge theories

In $SU(N)$ gauge theory, it is argued recently that there exists a "mixed
anomaly" between the CP symmetry and the 1-form $\mathbb{Z}_N$ symmetry at
$\theta=\pi$, and the anomaly matching requires CP to be spontaneously broken
at $\theta=\pi$ if the system is in the confining phase. In this paper, we
elaborate on this discussion by examining the large volume behavior of the
partition functions of the $SU(N)/\mathbb{Z}_N$ theory on $T^4$ a la 't Hooft.
The periodicity of the partition function in $\theta$, which is not $2\pi$ due
to fractional instanton numbers, suggests the presence of a phase transition at
$\theta=\pi$. We propose lattice simulations to study the distribution of the
instanton number in $SU(N)/\mathbb{Z}_N$ theories. A characteristic shape of
the distribution is predicted when the system is in the confining phase. The
measurements of the distribution may be useful in understanding the phase
structure of the theory.Comment: 18 pages, 1 figure, reference added, typo fixe
A Preferred Mass Range for Primordial Black Hole Formation and Black
  Holes as Dark Matter Revisited

Bird, et. al. and Sasaki, et. al. have recently proposed the intriguing
possibility that the black holes detected by LIGO could be all or part of the
cosmological dark matter. This offers an alternative to WIMPs and axions, where
dark matter could be comprised solely of Standard Model particles. The mass
range lies within an observationally viable window and the predicted merger
rate can be tested by future LIGO observations. In this paper, we argue that
non-thermal histories favor production of black holes near this mass range --
with heavier ones unlikely to form in the early universe and lighter black
holes being diluted through late-time entropy production. We discuss how this
prediction depends on the primordial power spectrum, the likelihood of black
hole formation, and the underlying model parameters. We find the prediction for
the preferred mass range to be rather robust assuming a blue spectral index
less than two. We consider the resulting relic density in black holes, and
using recent observational constraints, establish whether they could account
for all of the dark matter today.Comment: 8 pages, 3 figure
Quasinormal modes of Gauss-Bonnet-AdS black holes: towards holographic
  description of finite coupling

Here we shall show that there is no other instability for the
Einstein-Gauss-Bonnet-anti-de Sitter (AdS) black holes, than the eikonal one
and consider the features of the quasinormal spectrum in the stability sector
in detail. The obtained quasinormal spectrum consists from the two essentially
different types of modes: perturbative and non-perturbative in the Gauss-Bonnet
coupling $\alpha$. The sound and hydrodynamic modes of the perturbative branch
can be expressed through their Schwazrschild-AdS limits by adding a linear in
$\alpha$ correction to the damping rates: $\omega \approx Re(\omega_{SAdS}) -
Im(\omega_{SAdS}) (1 - \alpha \cdot ((D+1) (D-4) /2 R^2)) i$, where $R$ is the
AdS radius. The non-perturbative branch of modes consists of purely imaginary
modes, whose damping rates unboundedly increase when $\alpha$ goes to zero.
When the black hole radius is much larger than the anti-de Sitter radius $R$,
the regime of the black hole with planar horizon (black brane) is reproduced.
If the Gauss-Bonnet coupling $\alpha$ (or used in holography $\lambda_{GB}$) is
not small enough, then the black holes and branes suffer from the instability,
so that the holographic interpretation of perturbation of such black holes
becomes questionable, as, for example, the claimed viscosity bound violation in
the higher derivative gravity. For example, $D=5$ black brane is unstable at
$|\lambda_{GB}|>1/8$ and has anomalously large relaxation time when approaching
the threshold of instability.Comment: 22 pages, JHEP styl
The full Quantum Spectral Curve for $AdS_4/CFT_3$

The spectrum of planar N=6 superconformal Chern-Simons theory, dual to type
IIA superstring theory on $AdS_4 \times CP^3$, is accessible at finite coupling
using integrability. Starting from the results of [arXiv:1403.1859], we study
in depth the basic integrability structure underlying the spectral problem, the
Quantum Spectral Curve. The new results presented in this paper open the way to
the quantitative study of the spectrum for arbitrary operators at finite
coupling. Besides, we show that the Quantum Spectral Curve is embedded into a
novel kind of Q-system, which reflects the OSp(4|6) symmetry of the theory and
leads to exact Bethe Ansatz equations. The discovery of this algebraic
structure, more intricate than the one appearing in the $AdS_5/CFT_4$ case,
could be a first step towards the extension of the method to $AdS_3/CFT_2$.Comment: 43 + 27 pages, 7 figures. v4: text improved, more details and App D

BPS black holes from massive IIA on S$^6$

We present BPS black hole solutions in a four-dimensional $\mathcal{N}=2$
supergravity with an abelian dyonic gauging of the universal hypermultiplet
moduli space. This supergravity arises as the SU(3)-invariant subsector in the
reduction of massive IIA supergravity on a six-sphere. The solutions are
supported by non-constant scalar, vector and tensor fields and interpolate
between a unique $\textrm{AdS}_{2} \,\times\, \textrm{H}^2$ geometry in the
near-horizon region and the domain-wall DW$_{4}$ (four-dimensional) description
of the D2-brane at the boundary. Some special solutions with charged AdS$_{4}$
or non-relativistic scaling behaviours in the ultraviolet are also presented.Comment: 20 pages, 4 figures and 1 appendix. v2: New appendix, comments and

Determination of the properties of vector mesons in external magnetic
  field by Quenched $SU(3)$ Lattice QCD

We investigate the ground state energies of vector $\rho^{\pm}$ and $K^{\pm
*}$ mesons depending on the magnetic field value in the $SU(3)$ lattice gauge
theory. It has been shown that the energy of a vector particle depends on its
spin projection on the field axis. The magnetic dipole polarizability and
hyperpolarizabilities give significant contributions to the energy value which
prevents the formation of the charged vector meson condensate at high magnetic
fields. We calculate the g-factor of $\rho^{\pm}$ and $K^{\pm*}$ mesons and the
dipole magnetic polarizability of $\rho^{\pm}$ mesons.Comment: 26 pages, 13 figure
Ghost-free vector superfield actions in supersymmetric higher-derivative
  theories

We systematically construct ghost-free higher-derivative actions of Abelian
vector supermultiplets in four-dimensional ${\cal N}=1$ global supersymmetric
theories. After giving a simple example which illustrates that a naive
introduction of a higher-derivative term gives rise to a ghost, we discuss
possible building blocks for a ghost-free action and explicitly show that their
bosonic parts have no ghost mode and the auxiliary field $\boldsymbol{D}$ does
not propagate. Higher-derivative terms yield higher powers of the auxiliary
field $\boldsymbol{D}$ in the actions, and the D-term equations of motion
consequently admit multiple solutions in general. We confirm that the
well-known supersymmetric Dirac-Born-Infeld action falls into this class. We
further give another example in which the standard quadratic kinetic term
(Maxwell term) is corrected by a quartic term of the field strength. We also
discuss possible couplings to matter fields and a deformed D-term potential.Comment: 17 pages; v3: references added, published versio
On the `simple' form of the gravitational action and the
  self-interacting graviton

The so-called $\Gamma\Gamma$-form of the gravitational Lagrangian, long known
to provide its most compact expression as well as the most efficient generation
of the graviton vertices, is taken as the starting point for discussing General
Relativity as a theory of the self-interacting graviton. A straightforward but
general method of converting to a covariant formulation by the introduction of
a reference metric is given. It is used to recast the Einstein field equation
as the equation of motion of a spin-2 particle interacting with the canonical
energy-momentum tensor symmetrized by the standard Belinfante method applicable
to any field carrying nonzero spin. This represents the graviton field equation
in a form complying with the precepts of standard field theory. It is then
shown how representations based on other, at face value completely unrelated
definitions of energy-momentum (pseudo)tensors are all related by the addition
of appropriate superpotential terms. Specifically, the superpotentials are
explicitly constructed which connect to: i) the common definition consisting
simply of the nonlinear part of the Einstein tensor; ii) the Landau-Lifshitz
definition.Comment: 15 pages, latex, typos corrected, references added, published versio
Holographic Heat Current as Noether Current

We employ the Noether procedure to derive a general formula for the radially
conserved heat current in AdS planar black holes with certain transverse and
traceless perturbations, for a general class of gravity theories. For Einstein
gravity, the general higher-order Lovelock gravities and also a class of
Horndeski gravities, we derive the boundary stress tensor and show that the
resulting boundary heat current matches precisely the bulk Noether current.Comment: Latex, 27 pages, typos corrected, comments added, references adde
6D SCFTs and Phases of 5D Theories

Starting from 6D superconformal field theories (SCFTs) realized via F-theory,
we show how reduction on a circle leads to a uniform perspective on the phase
structure of the resulting 5D theories, and their possible conformal fixed
points. Using the correspondence between F-theory reduced on a circle and
M-theory on the corresponding elliptically fibered Calabi--Yau threefold, we
show that each 6D SCFT with minimal supersymmetry directly reduces to a
collection of between one and four 5D SCFTs. Additionally, we find that in most
cases, reduction of the tensor branch of a 6D SCFT yields a 5D generalization
of a quiver gauge theory. These two reductions of the theory often correspond
to different phases in the 5D theory which are in general connected by a
sequence of flop transitions in the extended Kahler cone of the Calabi--Yau
threefold. We also elaborate on the structure of the resulting conformal fixed
points, and emergent flavor symmetries, as realized by M-theory on a canonical
singularity.Comment: v2: 45 pages, 7 figures, references and clarifications adde
Conformal interfaces between free boson orbifold theories

We construct a large class of conformal interfaces between two-dimensional
c=1 conformal field theories describing compact free bosons and their Z_2
orbifolds. The interfaces are obtained by constructing boundary states in the
corresponding c=2 product theories and applying the unfolding procedure. We
compute the fusion products for all of these defects, and identify the
invertible topological interfaces associated to global symmetries, the
interfaces corresponding to marginal deformations, and the interfaces which map
the untwisted sector of an orbifold to the invariant states of the parent
theory.Comment: 28 pages + 15 pages of appendix, v2 added some references and

Witten Diagrams for Torus Conformal Blocks

We give a holographic description of global conformal blocks in two
dimensional conformal field theory on the sphere and on the torus. We show that
the conformal blocks for one-point functions on the torus can be written as
Witten diagrams in thermal AdS. This is accomplished by deriving a general
conformal Casimir equation for global conformal blocks, and showing that Witten
diagrams obey the same equation. We study the semi-classical limit of n-point
conformal blocks, and show that these equal the action of a network of bulk
world-lines obeying appropriate geodesic equations. We give an alternate
description in the Chern-Simons formulation of 3D gravity, where the conformal
blocks are described by networks of Wilson lines, and argue that these
formulations are equivalent.Comment: 32 pages, 6 figure
Geometric polarization of plasmas and Love numbers of AdS black branes

We use AdS/CFT holography to study how a strongly-coupled plasma polarizes
when the geometry where it resides is not flat. We compute the linear-response
polarization coefficients, which are directly related to the static two-point
correlation function of the stress-energy tensor. In the gravitational dual
description, these parameters correspond to the tidal deformation
coefficients---the Love numbers---of a black brane. We also compute the
coefficients of static electric polarization of the plasma.Comment: 23 pages, 9 figures. v2: Added references and acknowledgments. v3:

Corrections to holographic entanglement plateau

We investigate the robustness of the Araki-Lieb inequality in a
two-dimensional (2D) conformal field theory (CFT) on torus. The inequality
requires that $\Delta S=S(L)-|S(L-\ell)-S(\ell)|$ is nonnegative, where $S(L)$
is the thermal entropy and $S(L-\ell)$, $S(\ell)$ are the entanglement
entropies. Holographically there is an entanglement plateau in the BTZ black
hole background, which means that there exists a critical length such that when
$\ell \leq \ell_c$ the inequality saturates $\Delta S=0$. In thermal AdS
background, the holographic entanglement entropy leads to $\Delta S=0$ for
arbitrary $\ell$. We compute the next-to-leading order contributions to $\Delta
S$ in the large central charge CFT at both high and low temperatures. In both
cases we show that $\Delta S$ is strictly positive except for $\ell = 0$ or
$\ell = L$. This turns out to be true for any 2D CFT. In calculating the single
interval entanglement entropy in a thermal state, we develop new techniques to
simplify the computation. At a high temperature, we ignore the finite size
correction such that the problem is related to the entanglement entropy of
double intervals on a complex plane. As a result, we show that the leading
contribution from a primary module takes a universal form. At a low
temperature, we show that the leading thermal correction to the entanglement
entropy from a primary module does not take a universal form, depending on the
details of the theory.Comment: 32 pages, 8 figures; V2, typos corrected, published versio
Higher order gravities and the Strong Equivalence Principle

We show that, in all metric theories of gravity with a general covariant
action, gravity couples to the gravitational energy-momentum tensor in the same
way it couples to the matter energy-momentum tensor order by order in the weak
field approximation around flat spacetime. We discuss the relation of this
property to the Strong Equivalence Principle. We also study the gauge
transformation properties of the gravitational energy-momentum tensor.Comment: Additional resulting the gauge transformation of the gravitational

Isospin breaking corrections to meson masses and the hadronic vacuum
  polarization: a comparative study

We calculate the strong isospin breaking and QED corrections to meson masses
and the hadronic vacuum polarization in an exploratory study on a
$64\times24^3$ lattice with an inverse lattice spacing of $a^{-1}=1.78$ GeV and
an isospin symmetric pion mass of $m_\pi=340$ MeV. We include QED in an
electro-quenched setup using two different methods, a stochastic and a
perturbative approach. We find that the electromagnetic correction to the
leading hadronic contribution to the anomalous magnetic moment of the muon is
smaller than $1\%$ for the up quark and $0.1\%$ for the strange quark, although
it should be noted that this is obtained using unphysical light quark masses.
In addition to the results themselves, we compare the precision which can be
reached for the same computational cost using each method. Such a comparison is
also made for the meson electromagnetic mass-splittings.Comment: 49 pages, 20 figure
Tetrahedral modular graph functions

The low-energy expansion of one-loop amplitudes in type II string theory
generates a series of world-sheet integrals whose integrands can be represented
by world-sheet Feynman diagrams. These integrands are modular invariant and
understanding the structure of the action of the modular Laplacian on them is
important for determining their contribution to string scattering amplitudes.
In this paper we study a particular infinite family of such integrands
associated with three-loop scalar vacuum diagrams of tetrahedral topology and
find closed forms for the action of the Laplacian. We analyse the possible
eigenvalues and degeneracies of the Laplace operator by group- and
representation-theoretic means.Comment: 40 pages. v2: reference added. Version published in JHE
Machine Learning in the String Landscape

We utilize machine learning to study the string landscape. Deep data dives
and conjecture generation are proposed as useful frameworks for utilizing
machine learning in the landscape, and examples of each are presented. A
decision tree accurately predicts the number of weak Fano toric threefolds
arising from reflexive polytopes, each of which determines a smooth F-theory
compactification, and linear regression generates a previously proven
conjecture for the gauge group rank in an ensemble of $\frac43 \times 2.96
\times 10^{755}$ F-theory compactifications. Logistic regression generates a
new conjecture for when $E_6$ arises in the large ensemble of F-theory
compactifications, which is then rigorously proven. This result may be relevant
for the appearance of visible sectors in the ensemble. Through conjecture
generation, machine learning is useful not only for numerics, but also for
rigorous results.Comment: 35 pages, 4 figure
B physics Beyond the Standard Model at One Loop: Complete
  Renormalization Group Evolution below the Electroweak Scale

General analyses of $B$-physics processes beyond the Standard Model require
accounting for operator mixing in the renormalization-group evolution from the
matching scale down to the typical scale of $B$ physics. For this purpose the
anomalous dimensions of the full set of local dimension-six operators beyond
the Standard Model are needed. We present here for the first time a complete
and non-redundant set of dimension-six operators relevant for $B$-meson mixing
and decay, together with the complete one-loop anomalous dimensions in QCD and
QED. These results are an important step towards the automation of general New
Physics analyses.Comment: 37 pages, 3 figures + ancillary mathematica package. Version
