We report the first results of DarkSide-50, a direct search for dark matter operating in the underground Laboratori Nazionali del Gran Sasso (LNGS) and searching for the rare nuclear recoils possibly induced by weakly interacting massive particles (WIMPs). The dark matter detector is a Liquid Argon Time Projection Chamber with a (46.4 +/- 0.7) kg active mass, operated inside a 30 t organic liquid scintillator neutron veto, which is in turn installed at the center of a 1 kt water Cherenkov veto for the residual flux of cosmic rays. We report here the null results of a dark matter search for a (1422 +/- 67) kgd exposure with an atmospheric argon fill. This is the most sensitive dark matter search performed with an argon target, corresponding to a 90% CL upper limit on the WIMP-nucleon spin-independent cross section of 6.1 x 10(-44) cm(2) for a WIMP mass of 100 Gev/c(2).

• Dark matter direct-detection experiments (2015, methodology): “ring 2005-2006, was the rst LAr detector which produced dark matter search results. It was located at the LNGS laboratory in Italy and consisted of 2.3‘liquid argon. Currently, the DarkSide experiment[313] is operating with about 50kg active mass and rst results have shown a large light yield at ˘8p”
