About
DarkSide uses a dual-phase Liquid Argon Time Projection Chamber running since mid 2015 with a
50-kg-active-mass target from an underground source, to search for WIMP dark matter. The talk will present the latest result on the search for low mass WIMPs ($M_{WIMP} <20GeV/c^2$ ) extending the exclusion region below previous limits in the range $1.8-6 GeV/c^2$, as well as a search for high mass WIMPs ($M_{WIMP}>100GeV/c^2$) with 0 background reported in the signal region giving the most competitive result obtained with an Argon target.
The next stage of the Darkside program will be a new generation experiment involving a global collaboration from all the current Argon based experiments. DarkSide-20k is designed as a >20-tonne fiducial mass TPC with SiPM based photosensors, expected to achieve an instrumental background well below that from coherent scattering of solar and atmospheric neutrinos. Like its predecessor DarkSide-20k will be housed at the Gran Sasso (LNGS) underground laboratory, and it is expected to attain a WIMP-nucleon cross section exclusion sensitivity of $10^{-47}\, cm^2$ for a WIMP mass of $1 TeV/c^2$ in a 5 yr run. .
