A Simple Dark Matter Model to Explain the LZ Event and Galactic Center Excess
Caleb Gemmell, Dan Hooper, Gordan Krnjaic
We propose that the dark matter (DM) is a pseudo-Dirac fermion with a mass of approximately GeV that couples inelastically to the Standard Model through a hadrophilic spin…
Re-examining the sensitivity of JWST to decaying axion dark matter
Caleb Gemmell, Christopher Dessert, Andrea Caputo +1
An eV-scale QCD axion comprising the observed dark matter (DM) abundance is expected to generate a photon line at infrared energies that would be observable or near-observable in d…
Strongest constraints on dark acoustic oscillations from the Lyman-alpha forest
Zhihan Yuan, Caleb Gemmell, Keir K. Rogers +4
We set the first constraints on a small-scale dark acoustic oscillation (DAO) in the linear matter power spectrum arising from dark sector interactions, with a full forward model o…
Dark Matter, Baryon Number, and Cosmic-Ray Antinuclei
Caleb Gemmell, Dan Hooper, Seth Koren +1
Antideuterons and antihelium nuclei in the cosmic-ray spectrum have long been considered a smoking gun signature of dark matter annihilation, making the tentative observation of se…
Enhanced Cosmic-Ray Antinuclei Fluxes with Dark Matter Annihilation into SUEPs
Mattia Di Mauro, Caleb Gemmell, Austin Batz +4
Standard-Model (SM) hadronic parton showers initiated by secondary cosmic-ray production or dark matter (DM) annihilations robustly predict very low antinuclei yields and a strong…
