DarkSide-50 532-day dark matter search with low-radioactivity argon
Journal Article

· Physical Review D
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 (16 660 ± 270) kg d exposure using a target of low-radioactivity argon extracted from underground sources. Additionally, 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).
