Boosted Dark Matter Interpretation of the XENON1T Excess
Boosted Dark Matter Interpretation of the XENON1T Excess
We propose boosted dark matter (BDM) as a possible explanation for the excess of keV electron recoil events observed by XENON1T. BDM particles have velocities much larger than those typical of virialized dark matter, and, as such, BDM-electron scattering can naturally produce keV electron recoils. We show that the required …
