Absorption of Sub-MeV Fermionic Dark Matter by Electron Targets

3 Nov 2020 Jeff A. Dror Gilly Elor Robert McGehee Tien-Tien Yu

We study a new class of signals where fermionic dark matter is absorbed by bound electron targets. Fermionic absorption signals in direct detection and neutrino experiments are sensitive to dark matter with sub-MeV mass, probing a region of parameter space in which dark matter is otherwise challenging to detect...
