There is No Missing Satellites Problem. (arXiv:1711.06267v1 [astroph.CO])
Authors: Stacy Y. Kim, Annika H. G. Peter, Jonathan R. Hargis
A critical challenge to the cold dark matter (CDM) paradigm is that there are
fewer satellites observed around the Milky Way than found in simulations of
dark matter substructure. We show that there is a match between the observed
satellite counts corrected by the detection efficiency of the Sloan Digital Sky
Survey (for luminosities $L \gtrsim$ 340 L$_\odot$) and the number of luminous
satellites predicted by CDM, assuming an empirical relation between stellar
mass and halo mass. The "issing satellites problem", cast in terms of number
counts, is thus solved, and imply that luminous satellites inhabit subhalos as
small as 10$^7$10$^8$ M$_\odot$. The total number of Milky Way satellites
depends sensitively on the spatial distribution of satellites. We also show
that warm dark matter (WDM) models with a thermal relic mass smaller than 4 keV
are robustly ruled out, and that limits of $m_\text{WDM} \gtrsim 8$ keV from
the Milky Way are probable in the near future. Similarly stringent constraints
can be placed on any dark matter model that leads to a suppression of the
matter power spectrum on $\sim$10$^7$ M$_\odot$ scales. Measurements of
completely dark halos below $10^8$ M$_\odot$, achievable with substructure
lensing, are the next frontier for tests of CDM.

Cosmological Axion and Quark Nugget Dark Matter Model. (arXiv:1711.06271v1 [hepph])
Authors: Shuailiang Ge, Xunyu Liang, Ariel Zhitnitsky
We study a dark matter (DM) model offering a very natural explanation of two
(naively unrelated) problems in cosmology: the observed relation $\Omega_{\rm
DM}\sim\Omega_{\rm visible}$ and the observed asymmetry between matter and
antimatter in the Universe, known as the "baryogenesis" problem. In this
framework, both types of matter (dark and visible) have the same QCD origin,
form at the same QCD epoch, and both proportional to one and the same
dimensional parameter of the system, $\Lambda_{\rm QCD}$, which explains how
these two, naively distinct, problems could be intimately related, and could be
solved simultaneously within the same framework. More specifically, the DM in
this model is composed by two different ingredients: the (well studied) DM
axions and (lessstudied) the quark nuggets made of matter or antimatter. The
focus of the present work is the quantitative analysis of the relation between
these two distinct components contributing to the dark sector of the theory
determined by $\Omega_{\rm DM}\equiv [\Omega_{\rm DM}(\rm nuggets)+ \Omega_{\rm
DM}(\rm axion)]$. We argue that the nugget's DM component always traces the
visible matter density, i.e. $\Omega_{\rm DM}(\rm nuggets)\sim\Omega_{\rm
visible}$ and this feature is not sensitive to the parameters of the system
such as the axion mass $m_a$ or the misalignment angle $\theta_0$. It should be
contrasted with conventional axion production mechanism due to the misalignment
when $\Omega_{\rm DM}(\rm axion)$ is highly sensitive to the axion mass $m_a$
and the initial misalignment angle $\theta_0$. We also discuss the constraints
on this model related to the inflationary scale $H_I$, nonobservation of the
isocurvature perturbations, $r_T < 0.12$, and also, varies axions search
experiments.

Heavy quark radiation in NLO+PS POWHEG generators. (arXiv:1711.06281v1 [hepph])
Authors: L. Buonocore, P. Nason, F. Tramontano
In this paper we deal with radiation from heavy quarks in the context of
nexttoleading order calculations matched to parton shower generators. A new
algorithm for radiation from massive quarks is presented that has considerable
advantages over the one previously employed. We implement the algorithm in the
framework of the ${\tt POWHEGBOX}$, and compare it with the previous one in
the case of the ${\tt hvq}$ generator for bottom production in hadronic
collisions, and in the case of the ${\tt bb4l}$ generator for top production
and decay.

Loopholes in $Z^\prime$ searches at the LHC: exploring supersymmetric and leptophobic scenarios. (arXiv:1711.06302v1 [hepph])
Authors: Jack Y. Araz, Gennaro Corcella, Mariana Frank, Benjamin Fuks
Searching for heavy vector bosons $Z^\prime$, predicted in models inspired by
Grand Unification Theories, is among the challenging objectives of the LHC. The
ATLAS and CMS collaborations have looked for $Z^\prime$ bosons assuming that
they can decay only into Standard Model channels, and have set exclusion limits
by investigating dilepton, dijet and to a smaller extent topantitop final
states. In this work we explore possible loopholes in these $Z^\prime$ searches
by studying supersymmetric as well as leptophobic scenarios. We demonstrate the
existence of realizations in which the $Z^\prime$ boson automatically evades
the typical bounds derived from the analyses of the DrellYan invariantmass
spectrum. Dileptonic final states can in contrast only originate from
supersymmetric $Z^\prime$ decays and are thus accompanied by additional
effects. This feature is analyzed in the context of judiciously chosen
benchmark configurations, for which visible signals could be expected in future
LHC data with a $4\sigma7\sigma$ significance. Our results should hence
motivate an extension of the current $Z^\prime$ search program to account for
supersymmetric and leptophobic models.

$N\pi$ scattering in the Roper channel. (arXiv:1711.06334v1 [heplat])
Authors: M. Padmanath, C. B. Lang, Luka Leskovec, Sasa Prelovsek
We present results from our recent lattice QCD study of $N\pi$ scattering in
the positiveparity nucleon channel, where the puzzling Roper resonance
$N^*(1440)$ resides in experiment. Using a variety of hadron operators, that
include $qqq$like, $N\pi$ in $p$wave and $N\sigma$ in $s$wave, we
systematically extract the excited lattice spectrum in the nucleon channel up
to 1.65 GeV. Our lattice results indicate that N$\pi$ scattering in the elastic
approximation alone does not describe a lowlying Roper. Coupled channel
effects between $N\pi$ and $N\pi\pi$ seem to be crucial to render a lowlying
Roper in experiment, reinforcing the notion that this state could be a
dynamically generated resonance. After giving a brief motivation for studying
the Roper channel and the relevant technical details to this study, we will
discuss the results and the conclusions based on our lattice investigation and
in comparison with other lattice calculations.

Stationary black holes with stringy hair. (arXiv:1711.06357v1 [grqc])
Authors: Jens Boos, Valeri P. Frolov
We discuss properties of black holes which are pierced by special
configurations of cosmic strings. For static black holes we consider radial
strings in the limit when the number of strings grows to infinity while the
tension of each single string tends to zero. In a properly taken limit the
stressenergy tensor of the string distribution is finite. We call such matter
stringy matter. We present a solution of the Einstein equations for an
electrically charged static black hole with the stringy matter, with and
without cosmological constant. This solution is a warped product of two
metrics. One of them is a deformed twosphere whose Gaussian curvature is
determined by the energydensity of the stringy matter. We discuss the
embedding of a corresponding distorted sphere into a threedimensional
Euclidean space and formulate consistency conditions. We also found a relation
between the square of the Weyl tensor invariant of the four dimensional
spacetime of the stringy black holes and the energy density of the stringy
matter. In the second part of the paper, we discuss test stationary strings in
the Kerr geometry and in its KerrNUTA(d)S generalizations. Explicit solutions
for strings that are regular at the event horizon are obtained. Using these
solutions the stressenergy tensor of the stringy matter in these geometries is
calculated. Extraction of the angular momentum from rotating black holes by
such strings is also discussed.

Partial restoration of chiral symmetry in cold nuclear matter: the $\phi$meson case. (arXiv:1711.06358v1 [nuclth])
Authors: J.J. CobosMartínez, K Tsushima, G Krein, A W Thomas
The work presented at this workshop is divided into two parts. In the first
part, the mass and decay width of the $\phi$meson in cold nuclear matter are
computed in an effective Lagrangian approach. The medium dependence of these
properties are obtained by evaluating kaonantikaon loop contributions to the
$\phi$meson selfenergy, employing mediummodified kaon masses calculated
using the quarkmeson coupling model. The loop integral is regularized with a
dipole form factor, and the sensitivity of the results to the choice of cutoff
mass in the form factor is investigated. At normal nuclear matter density, we
find a downward shift of the $\phi$ mass by a few percent, while the decay
width is enhanced by an order of magnitude.
Our results support the literature which suggest that one should observe a
small downward mass shift and a large broadening of the decay width. In the
second part, we present $\phi$mesonnucleus bound state energies and
absorption widths for four selected nuclei, calculated by solving the
KleinGordon equation with complex optical potentials. The attractive potential
for the $\phi$meson in the nuclear medium originates from the inmedium
enhanced KK loop in the $\phi$meson selfenergy. The results suggest that the
$\phi$meson should form bound states with all the nuclei considered. However,
the identification of the signal for these predicted bound states will need
careful investigation because of their sizable absorption widths.

Dinstantons in Real Time Dynamics. (arXiv:1711.06365v1 [hepth])
Authors: Siwen Li, Shu Lin
Instanton is known to exist in Euclidean spacetime only. Their role in real
time dynamics is usually understood as tunneling effect by Wick rotation. We
illustrate other effects of instanton in holography by investigating 5d
effective gravity theory of the black D3braneDinstanton system. The
supergravity description of the D3braneDinstanton system is dual to the
super YangMills theory with topological excitations of the vacuum. We obtain
Euclidean correlators in the presence of instantons by analyzing of the
fluctuations of the bulk fields in the 5d effective theory. Furthermore,
analytic continuation of Euclidean correlators leads to retarded correlators,
which characterize real time dynamics. We find interestingly real time
fluctuations of topological charge can destroy instantons and the lifetime of
instanton is set by temperature. This implies instanton contribution to "real
time dynamics" is suppressed at high temperature, which is analogous to classic
field theory results that instanton contribution to "thermodynamics" is
suppressed at high temperature.

Approaching the asymptotics at the LHC. (arXiv:1711.06380v1 [hepph])
Authors: Norbert Bence, László Jenkovszky, István Szanyi
Recent results on the slope of the $pp$ diffraction cone measured by TOTEM at
$7$ and $8$ GeV show an unexpected rapid rise in $s$, close to $B(s)\sim
\ln^2$, rather than $\ln s$, typical of the Reggepole predictions. We show
that the new phenomenon can be accommodated by the inclusion of unitarity
corrections to a simple Regge (pomeron) pole exchange. Interestingly, the
odderon may also promote the acceleration of $B(s)$. The onset of the new
regime may be indicative of the approach to the asymptotic dynamics of strong
interactions. We analyse the new data together with other available forward
measurable in a unitarized Regge dipole. Unitarization proves crucial in
fitting the data, especially those on the slope $B(s)$ showing a change from
the $\ln (s)$ to $\ln^2 (s)$ behavior. Having fitted the free parameters of the
unitarized model to the data, we predict the behavior of the cross sections and
the slope at still higher energies, including those asymptotic.

Positivity bound on the imaginary part of the rightchiral tensor coupling \boldmath{$g_R$} in polarized top quark decay. (arXiv:1711.06432v1 [hepph])
Authors: S. Groote, J.G. Körner
We derive a positivity bound on the rightchiral tensor coupling Im $g_R$ in
polarized top quark decay by analyzing the angular decay distribution of the
threebody polarized top quark decay $t(\uparrow)\to b+\ell^+ +\nu_\ell$ in NLO
QCD. We obtain the bound $0.0420 \le$ Im $g_R \le 0.0420$.

A combined dark matter study of AMS02 antiprotons and FermiLAT gamma rays. (arXiv:1711.06460v1 [astroph.HE])
Authors: Alessandro Cuoco, Jan Heisig, Michael Korsmeier, Michael Krämer
Observations of cosmic rays are a sensitive probe of dark matter annihilation
in our Galaxy. In this article we present an analysis of the AMS02 antiproton
data, reducing cosmicray propagation uncertainties by fitting at the same time
dark matter and propagation parameters. The result exhibits a possible hint for
dark matter pointing to an annihilation cross section close to the thermal
value. We investigate the compatibility of this signal with a dark matter
interpretation of the Galactic center excess seen in the FermiLAT gammaray
data and discuss implications for dark matter models.

The Higgs properties in the MSSM after the LHC Run2. (arXiv:1711.06461v1 [hepph])
Authors: Jun Zhao
We scrutinize the parameter space of the SMlike Higgs boson in the minimal
supersymmetric standard model (MSSM) under current experimental constraints.
The constraints are from (i) the precison electroweak data and various flavor
observables; (ii) the direct 22 separate ATLAS searches in Run1; (iii) the
latest LHC Run2 Higgs data and trilepton search of electroweakinos. We
perform a scan over the parameter space and find that the Run2 data can
further exclude a part of parameter space. For the property of the SMlike
Higgs boson, its gauge couplings further approach to the SM values with a
deviation below 0.1\%, while its Yukawa couplings $hb\bar{b}$ and
$h\tau\bar\tau$ can still sizably differ from the SM predictions by several
tens percent.

Scattering of charmed baryons on nucleons. (arXiv:1711.06470v1 [hepph])
Authors: J. Haidenbauer, G. Krein
Chiral effective field theory is utilized for extrapolating results on the
$\Lambda_c N$ interaction, obtained in lattice QCD at unphysical (large) quark
masses, to the physical point. The pionmass dependence of the components that
constitute the $\Lambda_c N$ potential up to nexttoleading order
(pionexchange diagrams and fourbaryon contact terms) is fixed by information
from lattice QCD simulations. No recourse to SU(3) or SU(4) flavor symmetry is
made. It is found that the results of the HAL QCD Collaboration for quark
masses corresponding to $m_\pi = 410$$570$ MeV imply a moderately attractive
$\Lambda_c N$ interaction at $m_\pi = 138$ MeV with scattering lengths of
$a\approx 1$ fm for the $^1S_0$ as well as the $^3S_1$ partial waves. For such
an interaction the existence of a charmed counterpart of the hypertriton is
unlikely but four and/or fivebaryons systems with a $\Lambda_c$ baryon could
be indeed bound.

Semialigned two Higgs doublet model. (arXiv:1711.06499v1 [hepph])
Authors: Naoyuki Haba, Hiroyuki Umeeda, Toshifumi Yamada
In the leftright symmetric model based on $SU(2)_L\times SU(2)_R\times
U(1)_{BL}$ gauge symmetry, there appear heavy neutral scalar particles
mediating quark flavor changing neutral currents (FCNCs) at tree level. We
consider a situation where such FCNCs give the only sign of the leftright
model while $W_R$ gauge boson is decoupled, and name it "semialigned two Higgs
doublet model" because the model resembles a two Higgs doublet model with
mildlyaligned Yukawa couplings to quarks. We predict a correlation among
processes induced by quark FCNCs in the model, and argue that future precise
calculation of mesonantimeson mixings and CP violation therein may hint at the
semialigned two Higgs doublet model and the leftright model behind it.

Reaction rates and transport in neutron stars. (arXiv:1711.06520v1 [astroph.HE])
Authors: Andreas Schmitt, Peter Shternin
Understanding signals from neutron stars requires knowledge about the
transport inside the star. We review the transport properties and the
underlying reaction rates of dense hadronic and quark matter in the crust and
the core of neutron stars and point out open problems and future directions.

Impact of Beauty and Charm H1ZEUS Combined Measurements on PDFs and Determination of the Strong Coupling. (arXiv:1711.06573v1 [hepph])
Authors: A. Vafaee, A. Khorramian
In this QCD analysis, we investigate the impact of recent measurements of
heavyflavor charm and beauty cross sections data sets on the simultaneous
determination of Parton Distribution Functions (PDFs) and the strong coupling,
$\alpha_s(M^2_Z)$. We perform three different fits based on VariableFlavour
Number Scheme (VFNS) at the Leading Order (LO) and NexttoLeading Order (NLO)
and choose the full HERA run I and II combined data as a new measurement of
inclusive Deep Inelastic Scattering (DIS) cross sections for our base data set.
We show that including charm and beauty cross sections data reduces the
uncertainty of gluon distribution and improves the fit quality up to 4.1\% from
leading order to nexttoleading order and up to 1.7\% for only NLO without and
with beauty and charm data contributions.

Cosmological abundance of the QCD axion coupled to hidden photons. (arXiv:1711.06590v1 [hepph])
Authors: Naoya Kitajima, Toyokazu Sekiguchi, Fuminobu Takahashi
We study cosmological evolution of the QCD axion coupled to hidden photons.
For a moderately strong coupling, the motion of the axion field leads to
explosive production of hidden photons by tachyonic instability. We use lattice
simulations to evaluate the cosmological abundance of the QCD axion. In doing
so we incorporate the backreaction of the produced hidden photons on the axion
dynamics, which becomes significant in the nonlinear regime. We find that the
axion abundance is suppressed by at most ${\cal O}(10^{3})$ for the decay
constant $f_a = 10^{16}$ GeV, compared to the case without the coupling. For a
sufficiently large coupling, the motion of the QCD axion becomes strongly
damped, and as a result the axion abundance is enhanced. Our results show that
the cosmological upper bound on the axion decay constant can be relaxed by a
few hundred for a certain range of the coupling to hidden photons.

The Electroweak Vacuum Decay and the Gravitational Contribution. (arXiv:1711.06594v1 [hepph])
Authors: Alberto Salvio
Whether the Standard Model electroweak vacuum is stable, metastable or
unstable depends crucially on the top mass (and, to a lesser extent, on other
measurable quantities). These topics are reviewed and updated by taking into
account the most recent determination of the top and Higgs masses. Moreover,
the correction to the vacuum decay due to Einstein gravity is described. This
process is also discussed in a scenario, called softened gravity, which has
been proposed as a solution of the Higgs mass hierarchy problem.

Matter density, symmetry breaking, and neutrino oscillation. (arXiv:1711.06607v1 [hepph])
Authors: H. Mohseni Sadjadi, A. P. Khosravi Karchi
A proposal for the neutrino mass, based on neutrinoscalar field interaction,
is introduced. The scalar field, in turn, is nonminimally coupled to the Ricci
scalar, and hence relates the neutrino mass to the matter density. In a dense
region, the scalar field obeys the $Z_2$ symmetry, and the neutrino is
massless. In a diluted region, the $Z_2$ symmetry breaks and neutrino acquires
mass from the nonvanishing expectation value of the scalar field. We consider
this scenario in the framework of a spherical dense object whose outside is a
diluted region. In this background, we study the neutrino flavors oscillation,
along with the consequences of the theory on oscillation length and MSW effect.
This preliminary model may shed some lights on the existing anomalies within
the neutrino data, concerning the different oscillating behavior of the
neutrinos in regions with different densities.

Fully differential NNLO computations with MATRIX. (arXiv:1711.06631v1 [hepph])
Authors: Massimiliano Grazzini, Stefan Kallweit, Marius Wiesemann
We present the computational framework MATRIX which allows us to evaluate
fully differential cross sections for a wide class of processes at hadron
colliders in nexttonexttoleading order (NNLO) QCD. The processes we
consider are $2\to 1$ and $2\to 2$ hadronic reactions involving Higgs and
vector bosons in the final state. All possible leptonic decay channels of the
vector bosons are included for the first time in the calculations, by
consistently accounting for all resonant and nonresonant diagrams, offshell
effects and spin correlations. We briefly introduce the theoretical framework
MATRIX is based on, discuss its relevant features and provide a detailed
description of how to use MATRIX to obtain NNLO accurate results for the
various processes. We report reference predictions for inclusive and fiducial
cross sections of all the physics processes considered here and discuss their
corresponding uncertainties. MATRIX features an automatic extrapolation
procedure that allows us, for the first time, to control the systematic
uncertainties inherent to the applied NNLO subtraction procedure down to the
few permille level (or better).

Quark Mass Correction to Chiral Separation Effect and Pseudoscalar Condensate. (arXiv:1610.05886v2 [hepth] UPDATED)
Authors: Erdong Guo, Shu Lin
We derived an analytic structure of the quark mass correction to chiral
separation effect (CSE) in small mass regime. We confirmed this structure by a
D3/D7 holographic model study in a finite density, finite magnetic field
background. The quark mass correction to CSE can be related to correlators of
pseudoscalar condensate, quark number density and quark condensate in static
limit. We found scaling relations of these correlators with spatial momentum in
the small momentum regime. They characterize medium responses to electric
field, inhomogeneous quark mass and chiral shift. Beyond the small momentum
regime, we found existence of normalizable mode, which possibly leads to
formation of spiral phase. The normalizable mode exists beyond a critical
magnetic field, whose magnitude decreases with quark chemical potential.

Theory overview on amplitude analyses with charm decays. (arXiv:1611.05286v2 [hepph] UPDATED)
Authors: B. Loiseau
This contribution about amplitude analyses in multibody hadronic charm decays
deals with some attempts to introduce theoretical constraints. Different
effective hadronic formalism approaches are mentioned. A recent work, based on
a basic weak interaction process and a Chiral unitary model to account for the
final state interaction, is described in details for the $f_0(980)$ production
in $D_s^+ \to \pi^+ \pi^+ \pi^$ and $D_s^+ \to \pi^+ K^+ K^ $ decays. Within
the framework of the diagrammatic approach and flavor symmetry, a global
analysis of twobody $D$ decays into a vector meson and a pseudoscalar meson is
presented. A quasitwobody QCD factorization model for $D$ decays into three
mesons and its recent application to $D^0 \to K_S^0 \pi^+ \pi^$ is outlined.
For processes with finalstate pions and kaons and as an alternative to the sum
of BreitWigner amplitudes, often used in experimental Dalitzplot analyses,
amplitude parametrizations, in term of unitary $\pi \pi$, $\pi K$ and $K \bar
K$ form factors, are proposed. These parametrizations are derived from
quasitwobody factorization models.

Flavoured $BL$ Local Symmetry and Anomalous Rare $B$ Decays. (arXiv:1705.03858v2 [hepph] UPDATED)
Authors: Rodrigo Alonso, Peter Cox, Chengcheng Han, Tsutomu T. Yanagida
We consider a flavoured $BL$ gauge symmetry under which only the third
generation fermions are charged. Such a symmetry can survive at low energies
(~TeV) while still allowing for two superheavy righthanded neutrinos,
consistent with neutrino masses via seesaw and leptogenesis. We describe a
mechanism for generating Yukawa couplings in this model and also discuss the
lowenergy phenomenology. Interestingly, the new gauge boson could explain the
recent hints of lepton universality violation at LHCb, with a gauge coupling
that remains perturbative up to the Planck scale. Finally, we discuss more
general $U(1)$ symmetries and show that there exist only two classes of
vectorial $U(1)$ that are both consistent with leptogenesis and remain
phenomenologically viable at lowenergies.

Multiparticle production in the large lambda n limit: Realising Higgsplosion in a scalar QFT. (arXiv:1705.04365v3 [hepph] UPDATED)
Authors: Valentin V. Khoze
In a scalar theory which we use as a simplified model for the Higgs sector,
we adopt the semiclassical formalism of Son for computations of $n$particle
production crosssections in the highmultiplicity $n\to \infty$ weakcoupling
$\lambda \to 0$ regime with the value of $\lambda n$ held fixed and large. The
approach relies on the use of singular classical solutions to a certain
boundary value problem. In the past this formalism has been successfully used
and verified in computations of perturbative multiparticle processes at
treelevel, and also at the nexttoleading order level in the small $\lambda
n$ expansion near the multiparticle mass threshold. We apply this singular
solutions formalism in the regime of ultrahigh multiplicities where $\lambda n
\gg 1$, and compute the leading positive $\sim n\,\sqrt{\lambda n}$
contribution to the exponent of the multiparticle rate in this large $\lambda
n$ limit. The computation is carried out near the multiparticle mass threshold
where the multiplicity $n$ approaches its maximal value allowed by kinematics.
This calculation relies on the idea of Gorsky and Voloshin to use a thin wall
approximation for the singular solutions that resemble critical bubbles. This
approximation is justified in precisely the highmultiplicity $\sqrt{\lambda n}
\to \infty$ regime of interest. Based on our results we show that the scalar
theory with a spontaneous symmetry breaking used here as a simplified model for
the Higgs sector, is very likely to realise the highenergy Higgsplosion
phenomenon.

Spontaneous breakdown of charge in the MSSM and in the NMSSM: Possibilities and Implications. (arXiv:1705.08208v3 [hepph] UPDATED)
Authors: Jyotiranjan Beuria, AseshKrishna Datta
We study the possibilities and the implications of a spontaneous breakdown of
charge in the MSSM and in the $Z_3$symmetric NMSSM. The breakdown is triggered
by the charged states of the Higgs doublets acquiring vacuum expectation
values. In the MSSM, it is known that the presence of a charge conserving
minimum for the treelevel Higgs potential precludes a deeper (global)
chargebreaking minimum. We find that the inclusion of radiative correction to
the potential does not alter the situation while a deeper chargeconserving
minimum could arise, albeit with no major practical consequences. In the NMSSM
scenario, a chargebreaking global minimum, with or without an accompanying
chargeconserving deeper minimum, could appear even with the treelevel Higgs
potential thanks to the presence of a chargeneutral scalar state which
transforms as a singlet under the Standard Model gauge group. Use of the NMSSM
Higgs potential that includes both quantum and thermal corrections and the
requirement of a viable (stable or longlived) vacuum that breaks the
electroweak symmetry, along with its compatibility with the latest Higgs data,
lead to nontrivial constraints on the NMSSM parameter space.

Coannihilation without chemical equilibrium. (arXiv:1705.09292v2 [hepph] UPDATED)
Authors: Mathias Garny, Jan Heisig, Benedikt Lülf, Stefan Vogl
Chemical equilibrium is a commonly made assumption in the freezeout
calculation of coannihilating dark matter. We explore the possible failure of
this assumption and find a new conversiondriven freezeout mechanism.
Considering a representative simplified model inspired by supersymmetry with a
neutralino and sbottomlike particle we find regions in parameter space with
very small couplings accommodating the measured relic density. In this region
freezeout takes place out of chemical equilibrium and dark matter
selfannihilation is thoroughly inefficient. The relic density is governed
primarily by the size of the conversion terms in the Boltzmann equations. Due
to the small dark matter coupling the parameter region is immune to direct
detection but predicts an interesting signature of disappearing tracks or
displaced vertices at the LHC. Unlike freezein or superWIMP scenarios,
conversiondriven freezeout is not sensitive to the initial conditions at the
end of reheating.

Dual meson condensates in the Polyakovloop extended linear sigma model. (arXiv:1705.09953v2 [hepph] UPDATED)
Authors: Zhao Zhang, Haipeng Lu
Dual meson condensates as possible order parameters for deconfinement are
investigated in a Polyakovloop enhanced linear sigma model of QCD at both zero
and finite isospin chemical potential $\mu_I$. We find that the rapid rise of
the dual sigma condensate (corresponding to the dressed Polyakovloop) with $T$
is driven by the chiral transition, no matter whether the Polyakovloop
dynamics is included or not. For $\mu_I>m_\pi/2$, the dual sigma condensate
shows abnormal thermal behavior which even decreases with $T$ below the melting
temperature $T_c^{I_3}$ of pion superfluidity; On the other hand, even the dual
pion condensate always increases with $T$, its maximum slope locates exactly at
$T_c^{I_3}$ rather than the deconfinement temperature $T_c^{P}$ determined by
the Polyakovloop. All these are qualitatively consistent with the previous
results obtained in the NambuJonaLasinio type models. The dual vector meson
condensate for $\mu_I>m_\pi/2$ is also calculated. This quantity is more
sensitive to the chiral transition when taking into account the Diracsea
contribution. Our study further suggests that it should be cautious to use dual
observables to indicate the deconfinement transition, especially in QCD models.

Dark Matter, Neutrino mass, Cutoff for CosmicRay Neutrino, and Higgs Boson Invisible Decay from a Neutrino Portal Interaction. (arXiv:1706.07028v3 [hepph] UPDATED)
Authors: Wen Yin
We study an effective theory beyond the standard model (SM) where either of
two additional gauge singlets, a Majorana fermion and a real scalar,
constitutes all or some fraction of dark matter. In particular, we focus on the
masses of the two singlets in the range of O(10) MeVO(10) GeV, with a neutrino
portal interaction which plays important roles not only in particle physics but
also in cosmology and astronomy. We point out that the dark matter abundance
can be thermally explained with (co)annihilation, where the dark matter with a
mass greater than 2 GeV can be tested in future lepton colliders, CEPC, ILC,
FCCee and CLIC, in the light of the Higgs boson invisible decay. When the
gauge singlets are lighter than O(100)MeV, the interaction can affect the
neutrino propagation in the universe due to its annihilation with the cosmic
background neutrino into the gauge singlets. Although can not be the dominant
dark matter in this case, the singlets are produced by the invisible decay of
the Higgs boson at a rate fully within the reach of the future lepton
colliders. In particular, a high energy cutoff of cosmicray neutrino, which
may account for the nondetection of GreisenZatsepinKuzmin (GZK) neutrinos or
nonobservation of Glashow resonance, can be set. Interestingly, given the
cutoff and the mass (range) of the WIMP, a neutrino mass can be "measured"
kinematically.

Exploring light mediators with lowthreshold direct detection experiments. (arXiv:1707.08571v2 [hepph] UPDATED)
Authors: Felix Kahlhoefer, Suchita Kulkarni, Sebastian Wild
We explore the potential of future cryogenic direct detection experiments to
determine the properties of the mediator that communicates the interactions
between dark matter and nuclei. Due to their low thresholds and large
exposures, experiments like CRESSTIII, SuperCDMS SNOLAB and EDELWEISSIII will
have excellent capability to reconstruct mediator masses in the MeV range for a
large class of models. Combining the information from several experiments
further improves the parameter reconstruction, even when taking into account
additional nuisance parameters related to background uncertainties and the dark
matter velocity distribution. These observations may offer the intriguing
possibility of studying dark matter selfinteractions with direct detection
experiments.

Gravitino and Polonyi production in supergravity. (arXiv:1708.05393v3 [hepph] UPDATED)
Authors: Andrea Addazi, Sergei V. Ketov, Maxim Yu. Khlopov
We study production of gravitino and Polonyi particles in the minimal
StarobinskyPolonyi $\mathcal{N}=1$ supergravity with inflaton belonging to a
massive vector supermultiplet. Our model has only one free parameter given by
the scale of spontaneous SUSY breaking triggered by Polonyi chiral superfield.
The vector supermultiplet generically enters the action nonminimally, via an
arbitrary real function. This functon is chosen to generate the inflaton scalar
potential of the Starobinsky model. Our supergravity model can be reformulated
as an abelian supersymmetric gauge theory with the vector gauge superfield
coupled to two (Higgs and Polonyi) chiral superfields interacting with
supergravity, where the $U(1)$ gauge symmetry is spontaneously broken. We find
that Polonyi and gravitino particles are efficiently produced during inflation.
After inflation, perturbative decay of inflaton also produces Polonyi particles
that rapidly decay into gravitinos. As a result, a coherent picture of
inflation and dark matter emerges, where the abundance of produced gravitinos
after inflation fits the CMB constraints as a Super Heavy Dark Matter (SHDM)
candidate. Our scenario avoids the notorous gravitino and Polonyi problems with
the Big Bang Nucleosynthesis (BBN) and DM overproduction.

Measuring properties of a Heavy Higgs boson in the $H\to ZZ \to 4\ell$ decay. (arXiv:1708.05583v2 [hepph] UPDATED)
Authors: Jung Chang, Kingman Cheung, Jae Sik Lee, ChihTing Lu, Jubin Park
In many extensions of the standard model, there exist a few extra Higgs
bosons. Suppose a heavy neutral Higgs boson H is discovered at the LHC, one
could then investigate CP and CPT~ properties of its couplings to a pair of $Z$
bosons through $H \to ZZ \to 4\ell$. We use the helicityamplitude method to
write down the most general form for the angular distributions of the four
finalstate leptons, which can cover the case of CPeven, odd, and mixed
state for the Higgs boson. We figure out there are 9 types of angular
observables and all the $H$ couplings to $Z$ bosons can be fully determined by
exploiting them. A Higgsboson mass of 260 GeV below the $t\bar t$ threshold is
illustrated with full details. With a total of $10^3$ events of $H \to ZZ \to
4\ell$, one can determine the couplings up to 1220\% uncertainties.

Averaged Energy Conditions and Bouncing Universes. (arXiv:1708.08713v2 [hepth] UPDATED)
Authors: Massimo Giovannini
The dynamics of bouncing universes is characterized by violating certain
coordinate invariant restrictions on the total energymomentum tensor,
customarily referred to as energy conditions. Although there could be epochs
where the null energy condition is locally violated, it may perhaps be enforced
in an averaged sense. Explicit examples of this possibility are investigated in
different frameworks.

Dynamical vs geometric anisotropy in relativistic heavyion collisions: which one prevails?. (arXiv:1709.08602v2 [hepph] UPDATED)
Authors: L.V. Bravina, I.P. Lokhtin, L.V. Malinina, S.V. Petrushanko, A.M. Snigirev, E.E. Zabrodin
We study the influence of geometric and dynamical anisotropies on the
development of flow harmonics and, simultaneously, on the second and
thirdorder oscillations of femtoscopy radii. The analysis is done within the
Monte Carlo event generator HYDJET++, which was extended to dynamical
triangular deformations. It is shown that the merely geometric anisotropy
provides the results which anticorrelate with the experimental observations of
either $v_2$ (or $v_3$) or secondorder (or thirdorder) oscillations of the
femtoscopy radii. Decays of resonances significantly increase the emitting
areas but do not change the phases of the radii oscillations. In contrast to
the spatial deformations, the dynamical anisotropy alone provides the correct
qualitative description of the flow and the femtoscopy observables
simultaneously. However, one needs both types of the anisotropy to match
quantitatively the experimental data.

Global Anomalies, Discrete Symmetries, and Hydrodynamic Effective Actions. (arXiv:1710.03768v2 [hepth] UPDATED)
Authors: Paolo Glorioso, Hong Liu, Srivatsan Rajagopal
We derive effective actions for parityviolating fluids in both $(3+1)$ and
$(2+1)$ dimensions, including those with anomalies. As a corollary we confirm
the most general constitutive relations for such systems derived previously
using other methods. We discuss in detail connections between parityodd
transport and underlying discrete symmetries. In (3+1) dimensions we elucidate
connections between anomalous transport coefficients and global anomalies, and
clarify a previous puzzle concerning transports and local gravitational
anomalies.

Likelihood Analysis of the pMSSM11 in Light of LHC 13TeV Data. (arXiv:1710.11091v2 [hepph] UPDATED)

We use MasterCode to perform a frequentist analysis of the constraints on a
phenomenological MSSM model with 11 parameters, the pMSSM11, including
constraints from ~ 36/fb of LHC data at 13 TeV and PICO, XENON1T and PandaXII
searches for dark matter scattering, as well as previous accelerator and
astrophysical measurements, presenting fits both with and without the
$(g2)_{\mu}$ constraint. The pMSSM11 is specified by the following parameters:
3 gaugino masses $M_{1,2,3}$, a common mass for the firstand secondgeneration
squarks $m_{\tilde{q}}$ and a distinct thirdgeneration squark mass
$m_{\tilde{q}_3}$, a common mass for the firstand secondgeneration sleptons
$m_{\tilde l}$ and a distinct thirdgeneration slepton mass $m_{\tilde \tau}$,
a common trilinear mixing parameter $A$, the Higgs mixing parameter $\mu$, the
pseudoscalar Higgs mass $M_A$ and $\tan\beta$. In the fit including
$(g2)_{\mu}$, a Binolike $\tilde\chi^0_1$ is preferred, whereas a
Higgsinolike $\tilde \chi^0_1$ is favoured when the $(g2)_{\mu}$ constraint
is dropped. We identify the mechanisms that operate in different regions of the
pMSSM11 parameter space to bring the relic density of the lightest neutralino,
$\tilde\chi^0_1$, into the range indicated by cosmological data. In the fit
including $(g2)_{\mu}$, coannihilations with $\tilde \chi^0_2$ and the
Winolike $\tilde\chi^{\pm}_1$ or with nearlydegenerate first and
secondgeneration sleptons are favoured, whereas coannihilations with the
$\tilde \chi^0_2$ and the Higgsinolike $\tilde\chi^{\pm}_1$ or with first and
secondgeneration squarks may be important when the $(g2)_{\mu}$ constraint is
dropped. Prospects remain for discovering stronglyinteracting sparticles at
the LHC as well as for discovering electroweaklyinteracting sparticles at a
future linear $e^+ e^$ collider such as the ILC or CLIC.

Itoh, M. Iwasaki, et al. (128 additional authors not shown)
We search for the $J^{PC}=0^{}$ and $1^{+}$ light tetraquark states with
masses up to 2.46~GeV/$c^2$ in $\Upsilon(1S)$ and $\Upsilon(2S)$ decays with
data samples of $(102\pm 2)$ million and $(158\pm 4)$ million events,
respectively, collected with the Belle detector. No significant signals are
observed in any of the studied production modes, and 90\% credibility level
(C.L.) upper limits on their branching fractions in $\Upsilon(1S)$ and
$\Upsilon(2S)$ decays are obtained. The inclusive branching fractions of the
$\Upsilon(1S)$ and $\Upsilon(2S)$ decays into final states with $f_1(1285)$ are
measured to be ${\cal B}(\Upsilon(1S)\to f_1(1285)+anything)=(46\pm28({\rm
stat.})\pm13({\rm syst.}))\times 10^{4}$ and ${\cal B}(\Upsilon(2S)\to
f_1(1285)+anything)=(22\pm15({\rm stat.})\pm6.3({\rm syst.}))\times 10^{4}$.
The measured $\chi_{b2} \to J/\psi + anything$ branching fraction is measured
to be $(1.50\pm0.34({\rm stat.})\pm0.22({\rm syst.}))\times 10^{3}$, and 90\%
C.L. upper limits for the $\chi_{b0,b1} \to J/\psi + anything$ branching
fractions are found to be $2.3\times 10^{3}$ and $1.1\times 10^{3}$,
respectively. For ${\cal B}(\chi_{b1} \to \omega + anything)$, the branching
fraction is measured to be $(4.9\pm1.3({\rm stat.})\pm0.6({\rm syst.}))\times
10^{2}$. %($<3.68\times 10^{2}$ at 90\% C.L.). All results reported here are
the first measurements for these modes.

Effective field theory approach to transTeV supersymmetry: covariant matching, Yukawa unification and Higgs couplings. (arXiv:1711.04774v2 [hepph] UPDATED)
Authors: James D. Wells, Zhengkang Zhang
Dismissing traditional naturalness concerns while embracing the Higgs boson
mass measurement and unification motivates careful analysis of transTeV
supersymmetric theories. We take an effective field theory (EFT) approach,
matching the Minimal Supersymmetric Standard Model (MSSM) onto the Standard
Model (SM) EFT by integrating out heavy superpartners, and evolving MSSM and
SMEFT parameters according to renormalization group equations in each regime.
Our matching calculation is facilitated by the recent covariant diagrams
formulation of functional matching techniques, with the full oneloop SUSY
threshold corrections encoded in just 30 diagrams. Requiring consistent
matching onto the SMEFT with its parameters (those in the Higgs potential in
particular) measured at low energies, and in addition requiring unification of
bottom and tau Yukawa couplings at the scale of gauge coupling unification, we
detail the solution space of superpartner masses from the TeV scale to well
above. We also provide detailed views of parameter space where Higgs coupling
measurements have probing capability at future colliders beyond the reach of
direct superpartner searches at the LHC.
