Description
Observations at astronomical and cosmological levels suggest the existence of a new form of non-luminous matter that interacts gravitationally with baryonic matter. The XENON1T detector, located at the underground National Laboratory of Gran Sasso in Italy, was designed and built to detect nuclear recoils from particles that may constitute the nature of this Dark Matter, their existence emerging in theories beyond the Standard Model under the generic name of Weakly Interacting Massive Particles (WIMPs). Using a 2t of ultra-pure liquid Xenon as target mass, this double phased TPC which was operational from late 2016 to 2018, after a 1 $\text{t}\times\text{yr}$ exposure, exhibiting an ultra-low electronic recoil background, did not observed a significant excess of the number of events over the expected background, thus achieving to provide the most stringent limit, to date, on the WIMP-nucleon spin-independent elastic scattering cross-section for WIMP masses above 6 $\text{GeV}/\text{c}^2$.
In this talk I will present an overview of the XENON1T experiment, its latest results, as well as the prospects for its immediate upgrading, the XENONnT detector that is expected to increase the sensitivity by more than one order of magnitude.
