Limiting Light Dark Matter with Luminous Hadronic Loops
Joe Bramante, Melissa Diamond, Christopher V. Cappiello +1
Dark matter is typically assumed not to couple to the photon at tree level. While annihilation to photons through quark loops is often considered in indirect detection searches, su…
The Morphology of Exciting Dark Matter and the Galactic 511 keV Signal
Christopher V. Cappiello, Michael Jafs, Aaron C. Vincent
We study the morphology of the 511 keV signal that could be produced by exciting dark matter (XDM) in the Milky Way. In this model, collisions between dark matter particles excite…
An Analytic Approach to Light Dark Matter Propagation
Christopher Cappiello
If dark matter interacts too strongly with nuclei, it could be slowed to undetectable speeds in Earth's crust or atmosphere before ever reaching a detector. For sub-GeV dark matter…
