First Dark Matter Search Results from the XENON1T Experiment
Abstract
We report the first dark matter search results from XENON1T, a 2000-kg-target-mass dual-phase (liquid-gas) xenon time projection chamber in operation at the Laboratori Nazionali del Gran Sasso in Italy and the first ton-scale detector of this kind. The blinded search used 34.2 live days of data acquired between November 2016 and January 2017. Inside the (104212) kg fiducial mass and in the [5, 40] energy range of interest for WIMP dark matter searches, the electronic recoil background was events/(kg day ), the lowest ever achieved in a dark matter detector. A profile likelihood analysis shows that the data is consistent with the background-only hypothesis. We derive the most stringent exclusion limits on the spin-independent WIMP-nucleon interaction cross section for WIMP masses above 10 GeV/c, with a minimum of 7.7 cm for 35-GeV/c WIMPs at 90% confidence level.
