There are currently several existing and proposed experiments designed to probe sub-GeV dark matter (DM) using electron ionization in various materials. The projected signal rates for these experiments assume that this ionization yield arises only from DM scattering directly off electron targets, ignoring secondary ionization contributions from DM scattering off nuclear targets. In this work...
The Migdal Effect has seen a surge of interest in the last three years, particularly since Ibe et al (1707.07258) laid out the formalism for how to calculate an expected rate in a detector due to a dark matter signal. Multiple groups since then have expanded on this theoretical work to demonstrate the importance of such a signal in searching for sub-GeV dark matter, but all suffer from the...
We report on the status of WIMP dark matter by exploring the most invisible final state: neutrinos. We provide new model-independent limits on dark matter annihilation into neutrinos in a mass range spanning MeV to ZeV. Interestingly, our limits using the latest SuperK data are inching ever closer to the thermal relic cross section. We also show projections for the next generation of neutrino...
