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 x 10(-48) cm(2) (1.2 x 10(-47) cm(2)) for a WIMP mass of 100 GeV/c(2) (1 TeV/c(2)).

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 x 10(-48) cm(2) (1.2 x 10(-47) cm(2)) for a WIMP mass of 100 GeV/c(2) (1 TeV/c(2)).I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
