Cosmic Ray-Boosted Dark Matter at IceCube
Christopher Cappiello, Qinrui Liu, Gopolang Mohlabeng +1
Cosmic ray (CR) upscattering of dark matter is considered as one of the most straightforward mechanisms to accelerate ambient dark matter, making it detectable at high threshold, l…

How Effective is at Discovering Dark Radiation in a Cosmology with Heavy Particle Decay?
Katarina Bleau, Joseph Bramante, Christopher Cappiello
Any light relic which was in thermal equilibrium with the Standard Model before it freezes out results in a shift in the effective number of neutrino species, . This quant…

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…
