Direct Detection of Strongly Interacting Sub-GeV Dark Matter via Electron Recoils

15 May 2019Timon EmkenRouven EssigChris KouvarisMukul Sholapurkar

We consider direct-detection searches for sub-GeV dark matter via electron scatterings in the presence of large interactions between dark and ordinary matter. Scatterings both on electrons and nuclei in the Earth's crust, atmosphere, and shielding material attenuate the expected local dark matter flux at a terrestrial detector, so that such experiments lose sensitivity to dark matter above some critical cross section...
