Dark Matter Search Results from a One Ton-Year Exposure of XENON1T


XENON Collaboration; et al; Baudis, Laura; Brown, Adam; Capelli, Chiara; Galloway, Michelle; Kazama, Shingo; Kish, A; Reichard, Shayne; Wulf, J (2018). Dark Matter Search Results from a One Ton-Year Exposure of XENON1T. Physical Review Letters, 121(11):111302.

Abstract

We report on a search for weakly interacting massive particles (WIMPs) using 278.8 days of data collected with the XENON1T experiment at LNGS. XENON1T utilizes a liquid xenon time projection chamber with a fiducial mass of (1.30±0.01)  ton, resulting in a 1.0 ton yr exposure. The energy region of interest, [1.4,10.6]  keVee ([4.9,40.9] keVnr), exhibits an ultralow electron recoil background rate of [82-3+5(syst)±3(stat)]  events/(ton yr keVee). No significant excess over background is found, and a profile likelihood analysis parametrized in spatial and energy dimensions excludes new parameter space for the WIMP-nucleon spin-independent elastic scatter cross section for WIMP masses above 6  GeV/c2, with a minimum of 4.1×10-47  cm2 at 30  GeV/c2 and a 90% confidence level.
