abstract

We present the latest results from the search for light dark matter particle interactions with the DarkSide-50 dual-phase liquid argon time projection chamber. This analysis, based on the ionization signal only, improves the existing limits for spin-independent WIMP-nucleon interactions in the $[1.2, 3.6]$ GeV/c$^2$ mass range. The sensitivity is extended down to 40 MeV/c$^2$ by assuming the Migdal effect, responsible for an additional ionization signal from the recoiling atom. Finally, we set new constraints to interactions of dark matter particles with electrons in the final state, namely WIMPs, galactic axions, dark photons, and sterile neutrinos.
