Abstract

Dual-phase xenon time projection chamber is pushing the forefront of dark matter direct detection with both very large exposure and ultra-low background. The XENON1T experiment, which contains 2 tonne of liquid xenon as target, had reported the most sensitive dark matter search result in 2018. This result features the largest 1 tonne-year exposure with the lowest electronic recoil background level down to 82 events/ tonne/ year/ keVee in any dark matter experiment. This data place the most stringent limit on the spin-independent interaction cross section between dark matter and nucleons, with a minimum value of 4.7*10-47cm2 at a mass of 30 GeV. This talk will cover analysis and results from the most sensitive dark matter search with the XENON1T detector, together with an outlook of the future XENONnT experiment which will start commissioning in late 2019.
