Abstract
The XENON1T experiment searches for dark matter particles through theirscattering off xenon atoms in a 2 tonne liquid xenon target. The detector is adual-phase time projection chamber, which measures simultaneously thescintillation and ionization signals produced by interactions in target volume,to reconstruct energy and position, as well as the type of the interaction. Thebackground rate in the central volume of XENON1T detector is the lowestachieved so far with a liquid xenon-based direct detection experiment. In thiswork we describe the response model of the detector, the background and signalmodels, and the statistical inference procedures used in the dark mattersearches with a 1 tonne$\times$year exposure of XENON1T data, that leaded tothe best limit to date on WIMP-nucleon spin-independent elastic scattercross-section for WIMP masses above 6 GeV/c$^2$.
