New result from XENON1T

Most stringent result on WIMP dark matter ever.

The XENON collaboration publishes a new result from an unprecedeted dark matter exposure of 1 ton x year using the XENON1T experiment. The world-record, ultra-low background level achieved in this project allowed for the most sensitive dark-matter search ever. No statistically significant excess above the background level was observed and the tightest limit on spin-independent WIMP nucleon couplings was derived for WIMP masses above ~5 GeV/c².

The publication was submitted to PRL.
