Dark Matter Searches for Monoenergetic Neutrinos Arising from Stopped Meson Decay in the Sun

Carsten Rott, Seongjin In, Jason Kumar +1

Dark matter can be gravitationally captured by the Sun after scattering off solar nuclei. Annihilations of the dark matter trapped and accumulated in the centre of the Sun could re…

Issues and Opportunities in Exotic Hadrons

R. A. Briceno, T. D. Cohen, S. Coito +22

The last few years have been witness to a proliferation of new results concerning heavy exotic hadrons. Experimentally, many new signals have been discovered that could be pointing…

Monoenergetic Neutrinos From Dark Matter Annihilation: Issues of Exposure

Jason Kumar

We consider searches for dark matter annihilation in the Sun resulting in monoenergetic neutrinos, produced either directly or through the decay of stopped pions and kaons. We find…

Vector dark matter at the LHC

Jason Kumar, Danny Marfatia, David Yaylali

We consider monojet searches at the Large Hadron Collider (LHC) for spin-1 dark matter that interacts with quarks through a contact operator. If the dark matter particles are produ…

Same-sign Higgsino Production at the CERN LHC: How Not to Hunt for Natural Supersymmetry

Patrick Stengel, Xerxes Tata

We examine the prospects for detecting light charged higgsinos that are expected to be a necessary feature of natural SUSY models via $pp\to {\widetilde W}^\pm{\widetilde W}_1^\pm…

Lorentz Invariance Violation and IceCube Neutrino Events

Gaurav Tomar, Subhendra Mohanty, Sandip Pakvasa

The IceCube neutrino spectrum shows a flux which falls of as for sub PeV energies but there are no neutrino events observed above PeV. In particular the Glashow r…

Supersymmetry: Aspirations and Prospects

Xerxes Tata

The realization in the early 1980s that weak scale supersymmetry stabilizes the Higgs sector of the spectacularly successful Standard Model led several authors to explore whether l…

IceCube neutrinos, decaying dark matter, and the Hubble constant

Luis A. Anchordoqui, Vernon Barger, Haim Goldberg +4

Cosmological parameters deduced from the Planck measurements of anisotropies in the cosmic microwave background are at some tension with direct astronomical measurements of various…

Majorana dark matter through the Higgs portal under the vacuum stability lamppost

Luis A. Anchordoqui, Vernon Barger, Haim Goldberg +4

We study the vacuum stability of a minimal Higgs portal model in which the standard model (SM) particle spectrum is extended to include one complex scalar field and one Dirac fermi…

New physics with ultra-high-energy neutrinos

D. Marfatia, D. W. McKay, T. J. Weiler

Now that PeV neutrinos have been discovered by IceCube, we optimistically entertain the possibility that neutrinos with energy above 100 PeV exist. We evaluate the dependence of ev…

Searching for Dark Matter Annihilation to Monoenergetic Neutrinos with Liquid Scintillation Detectors

Jason Kumar, Pearl Sandick

We consider searches for dark matter annihilation to monoenergetic neutrinos in the core of the Sun. We find that liquid scintillation neutrino detectors have enhanced sensitivity…

Yukawa Unification and Sparticle Spectroscopy in Gauge Mediation Models

Ilia Gogoladze, Azar Mustafayev, Qaisar Shafi +1

We explore the implications of t-b-tau (and b-tau) Yukawa coupling unification condition on the fundamental parameter space and sparticle spectroscopy in the minimal gauge mediated…

Natural SUSY with a bino- or wino-like LSP

Howard Baer, Vernon Barger, Peisi Huang +3

In natural SUSY models higgsinos are always light because μ^2 cannot be much larger than M_Z^2, while squarks and gluinos may be very heavy. Unless gluinos are discovered at LHC13,…

Hyperfine splitting in muonic hydrogen constrains new pseudoscalar interactions

W. -Y. Keung, D. Marfatia

We constrain the possibility of a new pseudoscalar coupling between the muon and proton using a recent measurement of the 2S hyperfine splitting in muonic hydrogen.
