Inelastic Signatures of Electroweak Dark Matter
Juri Smirnov, Spencer Griffith, John F. Beacom
Minimal dark matter extended to include a Majorana and a Dirac multiplet coupled through the Higgs --- the HC-MDM model --- provides a compelling and predictive framework. We show…

Minimal Dark Matter: Generalized Framework and Direct-Detection Sensitivity
Spencer Griffith, Juri Smirnov, Laura Lopez-Honorez +1
Minimal electroweak dark matter models are compelling due to their simplicity, though calculations of their freezeout abundance are complicated by nonperturbative effects due to So…

Angular Distribution of Gamma Rays Produced in Proton-Proton Collisions
Spencer Griffith, John F. Beacom, Jung-Tsung Li +1
Accurate modeling of how high-energy proton-proton collisions produce gamma rays through the decays of pions and other secondaries is needed to correctly interpret astrophysical ob…
