Abstract: | We present the results of a search for dark matter weakly interacting massive particles (WIMPs) in the mass range below 20 GeV /c<SUP>2</SUP> using a target of low-radioactivity argon with a 6786.0 kg d exposure. The data were obtained using the DarkSide-50 apparatus at Laboratori Nazionali del Gran Sasso. The analysis is based on the ionization signal, for which the DarkSide-50 time projection chamber is fully efficient at 0.1 keV ee . The observed rate in the detector at 0.5 keV ee is about 1.5 event /keV ee/kg /d and is almost entirely accounted for by known background sources. We obtain a 90% C.L. exclusion limit above 1.8 GeV /c<SUP>2</SUP> for the spin-independent cross section of dark matter WIMPs on nucleons, extending the exclusion region for dark matter below previous limits in the range 1.8 - 6 GeV /c<SUP>2</SUP> . |
