Zero-Range Effective Field Theory for Resonant Wino Dark Matter III. Annihilation Effects

Eric Braaten, Evan Johnson, Hong Zhang

Near a critical value of the wino mass where there is a zero-energy S-wave resonance at the neutral-wino-pair threshold, low-energy winos can be described by a zero-range effective…

Time-Dependent Observables in Heavy Ion Collisions II: in Search of Pressure Isotropization in the Theory

Yuri V. Kovchegov, Bin Wu

To understand the dynamics of thermalization in heavy ion collisions in the perturbative framework it is essential to first find corrections to the free-streaming classical gluon f…

Time-Dependent Observables in Heavy Ion Collisions I: Setting up the Formalism

Bin Wu, Yuri V. Kovchegov

We adapt the Schwinger-Keldysh formalism to study heavy-ion collisions in perturbative QCD. Employing the formalism, we calculate the two-point gluon correlation function $G_{22}^{…

Zero-Range Effective Field Theory for Resonant Wino Dark Matter II. Coulomb Resummation

Eric Braaten, Evan Johnson, Hong Zhang

Near a critical value of the wino mass where there is a zero-energy S-wave resonance at the neutral-wino-pair threshold, low-energy winos can be described by a zero-range effective…

Probing the neutrino mass ordering with KM3NeT-ORCA: Analysis and perspectives

Francesco Capozzi, Eligio Lisi, Antonio Marrone

The discrimination of the two possible options for the neutrino mass ordering (normal or inverted) is a major goal for current and future neutrino oscillation experiments. Such goa…

Mass Dependence of Higgs Production at Large Transverse Momentum through a Bottom Quark Loop

Eric Braaten, Hong Zhang, Jia-Wei Zhang

In the production of the Higgs through a bottom-quark loop, the transverse momentum distribution of the Higgs at large is complicated by its dependence on two other important…

Fast flavor conversions of supernova neutrinos: Classifying instabilities via dispersion relations

Francesco Capozzi, Basudeb Dasgupta, Eligio Lisi +2

Supernova neutrinos can exhibit a rich variety of flavor conversion mechanisms. In particular, they can experience "fast" self-induced flavor conversions almost immediately above t…

Zero-Range Effective Field Theory for Resonant Wino Dark Matter I. Framework

Eric Braaten, Evan Johnson, Hong Zhang

The most dramatic "Sommerfeld enhancements" of neutral-wino-pair annihilation occur when the wino mass is near a critical value where there is a zero-energy S-wave resonance at the…

Searching for Dark Matter with Neutron Star Mergers and Quiet Kilonovae

Joseph Bramante, Tim Linden, Yu-Dai Tsai

We identify new astrophysical signatures of dark matter that implodes neutron stars (NSs), which could decisively test whether NS-imploding dark matter is responsible for missing p…

Vector-like Leptons: Muon g-2 Anomaly, Lepton Flavor Violation, Higgs Decays, and Lepton Non-Universality

Zijie Poh, Stuart Raby

In this paper, we consider the Standard Model (SM) with one family of vector-like (VL) leptons, which couple to all three families of the SM leptons. We study the constraints on th…

Mass Dependence of Higgs Production at Large Transverse Momentum

Eric Braaten, Hong Zhang, Jia-Wei Zhang

The transverse momentum distribution of the Higgs at large is complicated by its dependence on three important energy scales: , the top quark mass , and the Higgs m…

A Pati-Salam SUSY GUT with Yukawa Unification

Zijie Poh, Stuart Raby, Zi-zhi Wang

Previous studies of a three family Yukawa unified supersymmetric grand unified theory (SUSY GUT) with SO(10) or Pati-Salam (PS) gauge symmetry proposed by Raby and students show th…

Dark Kinetic Heating of Neutron Stars and An Infrared Window On WIMPs, SIMPs, and Pure Higgsinos

Masha Baryakhtar, Joseph Bramante, Shirley Weishi Li +2

We identify a largely model-independent signature of dark matter interactions with nucleons and electrons. Dark matter in the local galactic halo, gravitationally accelerated to ov…

Small- Asymptotics of the Quark Helicity Distribution: Analytic Results

Yuri V. Kovchegov, Daniel Pitonyak, Matthew D. Sievert

In this Letter, we analytically solve the evolution equations for the small- asymptotic behavior of the (flavor singlet) quark helicity distribution in the large- limit. Th…

Global constraints on absolute neutrino masses and their ordering

Francesco Capozzi, Eleonora Di Valentino, Eligio Lisi +3

Within the standard three-neutrino framework, the absolute neutrino masses and their ordering (either normal, NO, or inverted, IO) are currently unknown. However, the combination o…

Leptogenesis after Inflation in a Pati-Salam Model

Stuart Raby

In this talk I discuss a supersymmetric Pati-Salam model of fermion masses and mixing angles which fits low energy data. The model is then extended to include an inflationary secto…

Solar Neutrinos as a Probe of Dark Matter-Neutrino Interactions

Francesco Capozzi, Ian M. Shoemaker, Luca Vecchi

Sterile neutrinos at the eV scale have long been studied in the context of anomalies in short baseline neutrino experiments. Their cosmology can be made compatible with our underst…

Zhong-Bo Kang, Jian-Wei Qiu, Felix Ringer +2

We study the production and polarization of mesons within a jet in proton-proton collisions at the LHC. We define the -jet fragmentation function as a ratio of different…

Comment on "Single-inclusive jet production in electron-nucleon collisions through next-to-next-to-leading order in perturbative QCD" [Phys. Lett. B 763, 52--59 (2016)]

Geoffrey T. Bodwin, Eric Braaten

In the cross section for single-inclusive jet production in electron-nucleon collisions, the distribution of a quark in an electron appears at next-to-next-to-leading order. The nu…
