Description
DarkSide-50 is a direct WIMP dark matter detection experiment at Laboratori Nazionali del Gran Sasso (LNGS) that used argon as the target material. Exploiting the ionization signal from a dual-phase time projection chamber (TPC) filled with low radioactivity argon from an underground source, it has set the strongest limit against WIMP with a mass in the GeV/c2 region. A new analysis has recently been carried out with a larger exposure coupled with an improved understanding of the detector response. In this talk, I will give the details of the updated search for the low mass WIMP using only ionization signal.
