Indirect Searches of the Degenerate MSSM
Debtosh Chowdhury, Ketan M. Patel, Xerxes Tata +1
A degenerate sfermionic particle spectrum can escape constraints from flavor physics, and at the same time evade the limits from the direct searches if the degeneracy extends to th…
Gluino reach and mass extraction at the LHC in radiatively-driven natural SUSY
Howard Baer, Vernon Barger, James S. Gainer +4
Radiatively-driven natural SUSY (RNS) models enjoy electroweak naturalness at the level while respecting LHC sparticle and Higgs mass constraints. Gluino and top squark mass…
Connecting Dark Matter Annihilation to the Vertex Functions of Standard Model Fermions
Jason Kumar, Christopher Light
We consider scenarios in which dark matter is a Majorana fermion which couples to Standard Model fermions through the exchange of charged mediating particles. The matrix elements f…
Detecting kinematic boundary surfaces in phase space: particle mass measurements in SUSY-like events
Dipsikha Debnath, James S. Gainer, Can Kilic +3
We critically examine the classic endpoint method for particle mass determination, focusing on difficult corners of parameter space, where some of the measurements are not independ…
Natural generalized mirage mediation
Howard Baer, Vernon Barger, Hasan Serce +1
In the supersymmetric scenario known as mirage mediation (MM), the soft SUSY breaking terms receive comparable anomaly-mediation and moduli-mediation contributions leading to the p…
Vector dark matter annihilation with internal bremsstrahlung
Gulab Bambhaniya, Jason Kumar, Danny Marfatia +2
We consider scenarios in which the annihilation of self-conjugate spin-1 dark matter to a Standard Model fermion-antifermion final state is chirality suppressed, but where this sup…
Boxes, Boosts, and Energy Duality: Understanding the Galactic-Center Gamma-Ray Excess through Dynamical Dark Matter
Kimberly K. Boddy, Keith R. Dienes, Doojin Kim +3
Many models currently exist which attempt to interpret the excess of gamma rays emanating from the Galactic Center in terms of annihilating or decaying dark matter. These models ty…
Simultaneous Explanation of the and Puzzles: a Model Analysis
Bhubanjyoti Bhattacharya, Alakabha Datta, Jean-Pascal Guévin +2
and are two -decay measurements that presently exhibit discrepancies with the SM. Recently, using an effective field theory approach, it was demonstrated tha…
Directional Searches at DUNE for Sub-GeV Monoenergetic Neutrinos Arising from Dark Matter Annihilation in the Sun
Carsten Rott, Seongjin In, Jason Kumar +1
We consider the use of directionality in the search for monoenergetic sub-GeV neutrinos arising from the decay of stopped kaons, which can be produced by dark matter annihilation i…
Hidden Sector Hydrogen as Dark Matter: Small-scale Structure Formation Predictions and the Importance of Hyperfine Interactions
Kimberly K. Boddy, Manoj Kaplinghat, Anna Kwa +1
We study the atomic physics and the astrophysical implications of a model in which the dark matter is the analog of hydrogen in a secluded sector. The self interactions between dar…
Big Bang Nucleosynthesis in the presence of sterile neutrinos with altered dispersion relations
Elke Aeikens, Heinrich Päs, Sandip Pakvasa +1
Big Bang Nucleosynthesis imposes stringent bounds on light sterile neutrinos mixing with the active flavors. Here we discuss how altered dispersion relations can weaken such bounds…
Lines and Boxes: Unmasking Dynamical Dark Matter through Correlations in the MeV Gamma-Ray Spectrum
Kimberly K. Boddy, Keith R. Dienes, Doojin Kim +3
Identifying signatures of dark matter at indirect-detection experiments is generally more challenging for scenarios involving non-minimal dark sectors such as Dynamical Dark Matter…
Identifying Phase Space Boundaries with Voronoi Tessellations
Dipsikha Debnath, James S. Gainer, Can Kilic +3
Determining the masses of new physics particles appearing in decay chains is an important and longstanding problem in high energy phenomenology. Recently it has been shown that the…
Dark matter annihilation with s-channel internal Higgsstrahlung
Jason Kumar, Jiajun Liao, Danny Marfatia
We study the scenario of fermionic dark matter that annihilates to standard model fermions through an s-channel axial vector mediator. We point out that the well-known chirality su…
Gamma-ray Signals from Dark Matter Annihilation Via Charged Mediators
Jason Kumar, Pearl Sandick, Fei Teng +1
We consider a simplified model in which Majorana fermion dark matter annihilates to charged fermions through exchange of charged mediators. We consider the gamma-ray signals arisin…
Multi-channel assault on natural supersymmetry at the high luminosity LHC
Howard Baer, Vernon Barger, Michael Savoy +1
Recent clarifications of naturalness in supersymmetry robustly require the presence of four light higgsinos with mass ~100-300 GeV while gluinos and (top)-squarks may lie in the mu…
Randomness in the Dark Sector: Emergent Mass Spectra and Dynamical Dark Matter Ensembles
Keith R. Dienes, Jacob Fennick, Jason Kumar +1
In general, non-minimal models of the dark sector such as Dynamical Dark Matter posit the existence of an ensemble of individual dark components with differing masses, cosmological…
