Abstract

The most successful class of direct detection of WIMPs with masses from few GeV/c2 to TeV/c2 have utilized Liquid Xenon time projection chambers (TPCs). The XENON project adopted dual phase TPCs using ultra-pure liquid Xenon as both target and detection medium for WIMPs. The first ton-scale Liquid Xenon based TPC, XENON1T, is running at the Gran Sasso Laboratory. With an active mass inside the TPC of 2 tonnes, data were collected for 278.8 days live time. Within a fiducial mass of 1.3 tonne, this results in 1.0 tonne×year exposure. In the energy region of interest, the detector exhibits the lowest background ever obtained in direct dark matter search experiment. In these data no significant excess over background is found and the most stringent limits on WIMP-nucleon spin-independent elastic scattering cross section has been set for masses above 6 GeV/c2 with a minimum of 4.1×10-47cm2 at 30 GeV/c2.
