Description
DarkSide-50 is the current phase of the DarkSide direct dark matter search program, operating underground at the Laboratori Nazionali del Gran Sasso in Italy. The detector is a dual-phase argon Time Projection Chamber (TPC), designed for direct detection of Weakly Interacting Massive Particles, and housed within a veto system of liquid scintillator and water Cherenkov detectors. We will highlight recent results from a 532.4 live-days exposure using a target of low-radioactivity underground argon, including a low-mass dark matter search based on the ionization signal, which extends the exclusion region for spin-independent dark matter-nucleon coupling below previous limits in the mass range of 1.8-6 GeV/c^2.
