Jet fragmentation functions in proton-proton collisions using
  soft-collinear effective theory

The jet fragmentation function describes the longitudinal momentum
distribution of hadrons inside a reconstructed jet. We study the jet
fragmentation function in proton-proton collisions in the framework of
soft-collinear effective theory (SCET). We find that, up to power corrections,
the jet fragmentation function can be expressed as the ratio of the fragmenting
jet function and the unmeasured jet function. Using renormalization group
techniques, we are able to resum large logarithms of jet radii R in the
perturbative expansion of the cross section. We use our theoretical formalism
to describe the jet fragmentation functions for light hadron and heavy meson
production measured at the Large Hadron Collider (LHC). Our calculations agree
very well with the experimental data for the light hadron production. On the
other hand, although our calculations for the heavy meson production inside
jets are consistent with the PYTHIA simulation, they fail to describe the LHC
data. We find that the jet fragmentation function for heavy meson production is
very sensitive to the gluon-to-heavy-meson fragmentation function.Comment: 26 pages, 7 figures, published version at JHE
RG Flow and Thermodynamics of Causal Horizons in Higher-Derivative AdS
  Gravity

In arXiv:1508.01343 [hep-th], one of the authors proposed that in AdS/CFT the
gravity dual of the boundary $c$-theorem is the second law of thermodynamics
satisfied by causal horizons in AdS and this was verified for Einstein gravity
in the bulk. In this paper we verify this for higher derivative theories. We
pick up theories for which an entropy expression satisfying the second law
exists and show that the entropy density evaluated on the causal horizon in a
RG flow geometry is a holographic c-function. We also prove that given a theory
of gravity described by a local covariant action in the bulk a sufficient
condition to ensure holographic c-theorem is that the second law of causal
horizon thermodynamics be satisfied by the theory. This allows us to explicitly
construct holographic c-function in a theory where there is curvature coupling
between gravity and matter and standard null energy condition cannot be defined
although second law is known to hold. Based on the duality between c-theorem
and the second law of causal horizon thermodynamics proposed in
arXiv:1508.01343 [hep-th] and the supporting calculations of this paper we
conjecture that every Unitary higher derivative theory of gravity in AdS
satisfies the second law of causal horizon thermodynamics. If this is not true
then c-theorem will be violated in a unitary Lorentz invariant field theory.Comment: 30 pages, Latex, Three figures, Includes a short review of

Higher-point conformal blocks and entanglement entropy in heavy states

We consider conformal blocks of two heavy operators and an arbitrary number
of light operators in a (1+1)-d CFT with large central charge. Using the
monodromy method, these higher-point conformal blocks are shown to factorize
into products of 4-point conformal blocks in the heavy-light limit for a class
of OPE channels. This result is reproduced by considering suitable worldline
configurations in the bulk conical defect geometry. We apply the CFT results to
calculate the entanglement entropy of an arbitrary number of disjoint intervals
for heavy states. The corresponding holographic entanglement entropy calculated
via the minimal area prescription precisely matches these results from CFT.
Along the way, we briefly illustrate the relation of these conformal blocks to
Riemann surfaces and their associated moduli space.Comment: 41 pages, 10 figures. (Published version; typos corrected and

On one-loop entanglement entropy of two short intervals from OPE of
  twist operators

We investigate the one-loop entanglement entropy of two short intervals with
small cross ratio $x$ on a complex plane in two-dimensional conformal field
theory (CFT) using operator product expansion of twist operators. We focus on
the one-loop entanglement entropy instead of the general order $n$ R\'enyi
entropy, and this makes the calculation much easier. We consider the
contributions of stress tensor to order $x^{10}$, contributions of $W_3$
operator to order $x^{12}$, and contributions of $W_4$ operator to order
$x^{14}$. The CFT results agree with the ones in gravity.Comment: V1, 27 pages; V2, 27 pages, typos corrected, references added,

A General Framework of Automorphic Inflation

Automorphic inflation is an application of the framework of automorphic
scalar field theory, based on the theory of automorphic forms and
representations. In this paper the general framework of automorphic and modular
inflation is described in some detail, with emphasis on the resulting
stratification of the space of scalar field theories in terms of the group
theoretic data associated to the shift symmetry, as well as the automorphic
data that specifies the potential. The class of theories based on Eisenstein
series provides a natural generalization of the model of $j$-inflation
considered previously.Comment: 30 pages, corrected typo
Non-linear uplift Ans\"atze for the internal metric and the four-form
  field-strength of maximal supergravity

The uplift of SO(8) gauged N=8 supergravity to 11-dimensional supergravity is
well studied in the literature. It is given by consistent relations between the
respective vector and scalar fields of both theories. For example, recent work
provided non-linear uplift Ans\"atze for the scalar degrees of freedom on the
internal manifold: the inverse metric and the three-form flux with mixed index
structure. However, one always found the metric of the compactified manifold by
inverting the inverse metric --- a task that was only possible in particular
cases, e.g. for the G$_2$, SO(3)$\times$SO(3) or SU(3)$\times$U(1)$\times$U(1)
invariant solutions of 11-dimensional supergravity.
  In this paper, I present a direct non-linear uplift Ansatz for the internal
metric in terms of the four-dimensional scalars and the Killing forms on the
compactified background manifold. Based on this formula, I also find new uplift
Ans\"atze for the warp factor and the full three-form flux. Finally, I provide
a direct non-linear uplift Ansatz for the internal four-form field-strength in
terms of the metric, the flux as well as the four-dimensional scalars and
background Killing forms. This new formula does not require to calculate the
derivative of the flux.
  My results may be generalized to other compactifications, e.g. the reduction
from type IIB supergravity to five dimensions.Comment: 18page
Closed star product on noncommutative $\mathbb{R}^3$ and scalar field
  dynamics

We consider the noncommutative space $\mathbb{R}^3_\theta$, a deformation of
$\mathbb{R}^3$ for which the star product is closed for the trace functional.
We study one-loop IR and UV properties of the 2-point function for real and
complex noncommutative scalar field theories with quartic interactions and
Laplacian on $\mathbb{R}^3$ as kinetic operator. We find that the 2-point
functions for these noncommutative scalar field theories have no IR
singularities in the external momenta, indicating the absence of UV/IR mixing.
We also find that the 2-point functions are UV finite with the deformation
parameter $\theta$ playing the role of a natural UV cut-off. The possible
origin of the absence of UV/IR mixing in noncommutative scalar field theories
on $\mathbb{R}^3_\theta$ as well as on $\mathbb{R}^3_\lambda $, another
deformation of $\mathbb{R}^3$, is discussed.Comment: 19 page
New decay modes of heavy Higgs bosons in a two Higgs doublet model with
  vectorlike leptons

In models with extended Higgs sector and additional matter fields, the decay
modes of heavy Higgs bosons can be dominated by cascade decays through the new
fermions rendering present search strategies ineffective. We investigate new
decay topologies of heavy neutral Higgses in two Higgs doublet model with
vectorlike leptons. We also discuss constraints from existing searches and
discovery prospects. Among the most interesting signatures are monojet, mono Z,
mono Higgs, and Z and Higgs bosons produced with a pair of charged leptons.Comment: 16 pages, 6 figure
NNLL resummation for stop pair-production at the LHC

The production of supersymmetric stop-antistop pairs at the Large Hadron
Collider (LHC) is studied including corrections from soft-gluon resummation up
to next-to-next-to-leading logarithmic (NNLL) accuracy in the Mellin-space
approach. Additionally, corrections to the hard-matching coefficient at
one-loop and Coulomb contributions at two-loop order are considered. The NNLL
corrections enhance the cross section for all stop masses at centre-of-mass
energies of 8 and 13 TeV compared to the previously calculated predictions at
next-to-leading logarithmic (NLL) accuracy. Furthermore, a slight increase in
the dependence on the additional stop-mixing parameters is observed.Comment: 24 pages, 7 figures; version published in JHE
One jet to rule them all: monojet constraints and invisible decays of a
  750 GeV diphoton resonance

The ATLAS and CMS collaborations recently reported a mild excess in the
diphoton final state pointing to a resonance with a mass of around 750 GeV and
a potentially large width. We consider the possibility of a scalar resonance
being produced via gluon fusion and decaying to electroweak gauge bosons, jets
and pairs of invisible particles, stable at collider scales. We compute limits
from monojet searches on such a resonance and test their compatibility with the
requirement for a large width. We also study whether the stable particle can be
a a dark matter candidate and investigate the corresponding relic density
constraints along with the collider limits. We show that monojet searches rule
out a large part of the available parameter space and point out scenarios where
a broad diphoton resonance can be reconciled with monojet constraints.Comment: Matches published versio
Scalar field as an intrinsic time measure in coupled dynamical
  matter-geometry systems. II. Electrically charged gravitational collapse

Investigating the dynamics of gravitational systems, especially in the regime
of quantum gravity, poses a problem of measuring time during the evolution. One
of the approaches to this issue is using one of the internal degrees of freedom
as a time variable. The objective of our research was to check whether a scalar
field or any other dynamical quantity being a part of a coupled multi-component
matter-geometry system can be treated as a `clock' during its evolution. We
investigated a collapse of a self-gravitating electrically charged scalar field
in the Einstein and Brans-Dicke theories using the 2+2 formalism. Our findings
concentrated on the spacetime region of high curvature existing in the vicinity
of the emerging singularity, which is essential for the quantum gravity
applications. We investigated several values of the Brans-Dicke coupling
constant and the coupling between the Brans-Dicke and the electrically charged
scalar fields. It turned out that both evolving scalar fields and a function
which measures the amount of electric charge within a sphere of a given radius
can be used to quantify time nearby the singularity in the dynamical spacetime
part, in which the apparent horizon surrounding the singularity is spacelike.
Using them in this respect in the asymptotic spacetime region is possible only
when both fields are present in the system and, moreover, they are coupled to
each other. The only nonzero component of the Maxwell field four-potential
cannot be used to quantify time during the considered process in the
neighborhood of the whole central singularity. None of the investigated
dynamical quantities is a good candidate for measuring time nearby the Cauchy
horizon, which is also singular due to the mass inflation phenomenon.Comment: 31 pages, 15 figure
Thinking outside the ROCs: Designing Decorrelated Taggers (DDT) for jet
  substructure

We explore the scale-dependence and correlations of jet substructure
observables to improve upon existing techniques in the identification of highly
Lorentz-boosted objects. Modified observables are designed to remove
correlations from existing theoretically well-understood observables, providing
practical advantages for experimental measurements and searches for new
phenomena. We study such observables in $W$ jet tagging and provide
recommendations for observables based on considerations beyond signal and
background efficiencies
Emergent space-time and the supersymmetric index

It is of interest to find criteria on a 2d CFT which indicate that it gives
rise to emergent gravity in a macroscopic 3d AdS space via holography.
Symmetric orbifolds in the large $N$ limit have partition functions which are
consistent with an emergent space-time string theory with $L_{\rm string} \sim
L_{\rm AdS}$. For supersymmetric CFTs, the elliptic genus can serve as a
sensitive probe of whether the SCFT admits a large radius gravity description
with $L_{\rm string} \ll L_{\rm AdS}$ after one deforms away from the symmetric
orbifold point in moduli space. We discuss several classes of constructions
whose elliptic genera strongly hint that gravity with $L_{\rm Planck} \ll
L_{\rm string} \ll L_{\rm AdS}$ can emerge at suitable points in moduli space.Comment: 29 pages, 2 figures; v2, very minor changes; v3, very minor additions

Sensitivity of NEXT-100 to neutrinoless double beta decay

NEXT-100 is an electroluminescent high-pressure xenon gas time projection
chamber that will search for the neutrinoless double beta ($\beta \beta 0 \nu$)
decay of Xe-136. The detector possesses two features of great value for $\beta
\beta 0 \nu$ searches: energy resolution better than 1\% FWHM at the $Q$ value
of Xe-136 and track reconstruction for the discrimination of signal and
background events. This combination results in excellent sensitivity, as
discussed in this paper. Material-screening measurements and a detailed Monte
Carlo detector simulation predict a background rate for NEXT-100 of at most
$4\times10^{-4}$ counts keV$^{-1}$ kg$^{-1}$ yr$^{-1}$. Accordingly, the
detector will reach a sensitivity to the \bbonu-decay half-life of
$2.8\times10^{25}$ years (90\% CL) for an exposure of 100
$\mathrm{kg}\cdot\mathrm{year}$, or $6.0\times10^{25}$ years after a run of 3
effective years.Comment: Accepted for publication in the Journal of High Energy Physics (JHEP
Quantum Quenches in Free Field Theory: Universal Scaling at Any Rate

Quantum quenches display universal scaling in several regimes. For quenches
which start from a gapped phase and cross a critical point, with a rate slow
compared to the initial gap, many systems obey Kibble-Zurek scaling. More
recently, a different scaling behaviour has been shown to occur when the quench
rate is fast compared to all other physical scales, but still slow compared to
the UV cutoff. We investigate the passage from fast to slow quenches in scalar
and fermionic free field theories with time dependent masses for which the
dynamics can be solved exactly for all quench rates. We find that renormalized
one point functions smoothly cross over between the regimes.Comment: 40 pages; v2: a bit late, but it includes minor modifications to

Heavy-tailed chiral random matrix theory

We study an unconventional chiral random matrix model with a heavy-tailed
probabilistic weight. The model is shown to exhibit chiral symmetry breaking
with no bilinear condensate, in analogy to the Stern phase of QCD. We solve the
model analytically and obtain the microscopic spectral density and the smallest
eigenvalue distribution for an arbitrary number of flavors and arbitrary quark
masses. Exotic behaviors such as non-decoupling of heavy flavors and a
power-law tail of the smallest eigenvalue distribution are illustrated.Comment: 18 pages, 5 figure
The BFSS model on the lattice

We study the maximally supersymmetric BFSS model at finite temperature and
its bosonic relative. For the bosonic model in $p+1$ dimensions, we find that
it effectively reduces to a system of gauged Gaussian matrix models. The
effective model captures the low temperature regime of the model including one
of its two phase transitions. The mass becomes $p^{1/3}\lambda^{1/3}$ for large
$p$, with $\lambda$ the 'tHooft coupling. Simulations of the bosonic-BFSS model
with $p=9$ give $m=(1.965\pm .007)\lambda^{1/3}$, which is also the mass gap of
the Hamiltonian. We argue that there is no `sign' problem in the maximally
supersymmetric BFSS model and perform detailed simulations of several
observables finding excellent agreement with AdS/CFT predictions when
$1/\alpha'$ corrections are included.Comment: 23 pages, 11 figure
A realistic model for Dark Matter interactions in the neutrino portal
  paradigm

We discuss a simple extension of the Standard Model (SM) that provides an
explicit realization of the dark-matter (DM) neutrino-portal paradigm. The dark
sector is composed of a scalar $ \Phi $ and a Dirac fermion $ \Psi $, with the
latter assumed to be lighter than the former. These particles interact with the
SM through the exchange of a set of heavy Dirac fermion mediators that are
neutral under all local SM symmetries, and also under the dark-sector symmetry
that stabilizes the $ \Psi $ against decay. We show that this model can
accommodate all experimental and observational constraints provided the DM mass
is below $\sim 35\, \gev $ or is in a resonant region of the Higgs or $Z$
boson. We also show that if the dark scalar and dark fermion are almost
degenerate in mass, heavier DM fermions are not excluded. We note that in this
scenario DM annihilation in the cores of astrophysical objects and the galactic
halo produces a monochromatic neutrino beam of energy $ \mfe $, which provides
a clear signature for this paradigm. Other experimental signatures are also
discussed.Comment: 21 pages, 8 figures. Published versio
Probing the Higgs Sector of the Minimal Left-Right Symmetric Model at
  Future Hadron Colliders

If neutrino masses arise from a TeV-scale minimal Left-Right seesaw model,
the ensuing extended Higgs sector with neutral, singly and doubly-charged
scalars has a plethora of implications for new Higgs boson searches beyond the
Standard Model at future hadron colliders, such as the $\sqrt s=14$ TeV
High-Luminosity Large Hadron Collider (HL-LHC) and the proposed $\sqrt s=100$
TeV collider (FCC-hh or SPPC). In this article, we provide a glimpse of this
new physics in the Higgs sector. Our discussion focuses on the minimal
non-supersymmetric version of the Left-Right model with high-scale parity
breaking but TeV-scale $SU(2)_R$-breaking, a property desirable to suppress the
type-II seesaw contribution to neutrino masses. We analyze the masses and
couplings of the physical Higgs bosons in this model, and discuss their
dominant production and decay modes at hadron colliders. We identify the best
discovery channels for each of the non-SM Higgs bosons and estimate the
expected SM backgrounds in these channels to derive the sensitivity reaches for
the new Higgs sector at future hadron colliders under discussion. Following a
rather conservative approach, we estimate that the heavy Higgs sector can be
effectively probed up to 15 TeV at the $\sqrt s=100$ TeV machine. We also
discuss how the LR Higgs sector can be distinguished from other extended Higgs
sectors.Comment: 51 pages, 12 figures, 14 tables, sensitivity analysis improved, some

Polarised antibranes from Smarr relations

We study the backreaction of smeared and localised anti M2-branes placed at
the tip of the CGLP background. To this end we derive a Smarr relation for
backreacted antibranes at zero and finite temperature. For extremal antibranes
we show that if smeared they cannot have regular horizons, whereas localised
M2-branes can potentially be regular when polarised into M5-branes, in
agreement with the probe result of Klebanov and Pufu. We further discuss
antibranes at finite temperature and argue that localised antibrane solutions
with regular horizons are not excluded.Comment: 26 pages, 3 figure
Strong electroweak phase transition from Supersymmetric Custodial
  Triplets

The Supersymmetric Custodial Triplet Model, a supersymmetric generalization
of the Georgi-Machacek model, has proven to be an interesting modification of
the MSSM. It extends the MSSM Higgs sector by three extra SU(2)L triplets in
such a way that approximate custodial invariance is preserved and rho-parameter
deviations are kept under control. By means of a sizeable triplet contribution
to electroweak breaking the model is able to generate a barrier at tree level
between the false vacuum and the electroweak one. This will result in a strong
first order phase transition for an important region of the parameter space. We
also look at the gravitational waves that could be generated as a result of the
phase transition and show how future interferometers could be used as a probe
of the model.Comment: 18 pages, 8 figure
Moduli mediation without moduli-induced gravitino problem

We study the moduli-induced gravitino problem within the framework of the
phenomenologically attractive mirage mediations. The huge amount of gravitino
generated by the moduli decay can be successfully diluted by introducing an
extra light modulus field which does not induce the supersymmetry breaking.
Since the lifetime of extra modulus field becomes longer than usually
considered modulus field, our proposed mechanism is applied to both the low-
and high-scale supersymmetry breaking scenarios. We also point out that such an
extra modulus field appears in the flux compactification of type II string
theory.Comment: 24 pages, 2 figure
Surprises from the resummation of ladders in the ABJ(M) cusp anomalous
  dimension

We study the cusp anomalous dimension in N=6 ABJ(M) theory, identifying a
scaling limit in which the ladder diagrams dominate. The resummation is encoded
into a Bethe-Salpeter equation that is mapped to a Schroedinger problem,
exactly solvable due to the surprising supersymmetry of the effective
Hamiltonian. In the ABJ case the solution implies the diagonalization of the
U(N) and U(M) building blocks, suggesting the existence of two independent cusp
anomalous dimensions and an unexpected exponentiation structure for the related
Wilson loops. While consistent with previous perturbative analysis, the strong
coupling limit of our result does not agree with the string theory computation,
emphasizing a difference with the analogous resummation in the N=4 case.Comment: 26 pages, 4 figures, references added, published versio
