Abstract
The DarkSide-50 direct-detection dark matter experiment is a dual-phase argon time projection chamber operating at Laboratori Nazionali del Gran Sasso. This paper reports on the blind analysis of a (16660±270) kg d exposure using a target of low-radioactivity argon extracted from underground sources. We find no events in the dark matter selection box and set a 90% C.L. upper limit on the dark matter–nucleon spin-independent cross section of 1.14 × 10−44 cm2 (3.78 × 10−44 cm2, 3.43 × 10−43 cm2) for a WIMP mass of 100 GeV=c2 (1 TeV=c2, 10 TeV=c2).File in questo prodotto:
