Abstract

New results on the scattering cross-section between dark matter particles and nuclei and electrons are presented. They are obtained using a live- days exposure of 532.4 days from the DarkSide-50 experiment, which is a dual-phase liquid-argon time projection chamber (LAr TPC) installed at Laboratori Nazionali del Gran Sasso (LNGS). In this paper, the DarkSide-20k experiment, a LAr TPC with an active (fiducial) mass of 23 t (20 t) to be built at LNGS, is also reviewed. Thanks to its exceptionally low instrumental background, DarkSide-20k will be able to exclude cross sections between weakly interacting massive particles (WIMPs) and nuclei at 90% confidence level down to 2.8×10−48 cm2 (1.2×10−47 cm2) for a WIMP mass of 100 GeV/c2 (1 TeV/c2 ).
