We conducted a search for dark matter particles with sub-GeV/c2 masses that interact with electrons as final state particles using data from the DarkSide-50 experiment, which was based on low-radioactivity liquid argon exposure. Through analysis of the ionization signals, we were able to exclude previously unexplored parameter space for dark matter-electron interaction, including the cross section sigma over bar e, the axioelectric coupling constant gAe, and the dark photon kinetic mixing parameter kappa. Additionally, we established the first direct-detection constraints on the mixing angle IUe412 for keV/c2 sterile neutrinos.
We present a search for dark matter particles with sub-GeV/c2 masses whose interactions have final state electrons using the DarkSide-50 experiment's (12 306 1 184) kg d low-radioactivity liquid argon exposure. By analyzing the ionization signals, we exclude new parameter space for the dark matter-electron cross section sigma over bar e, the axioelectric coupling constant gAe, and the dark photon kinetic mixing parameter kappa. We also set the first dark matter direct-detection constraints on the mixing angle IUe412 for keV/c2 sterile neutrinos.
