Details of the first XENON1T science run analysis.
Di Gangi P.
XENON1T, at the Laboratori Nazionali del Gran Sasso, is the first tonne-scale double-phase xenon TPC, dedicated to the direct search of dark matter. Data collected during 34 live days have been analysed for a total exposure of 35.6 tonnes days. In this communication we describe the details of the data analysis of the XENON1T first run. Stability, performances and backgrounds of such new large detector have been studied and are well understood. This allows to derive the first limit of XENON1T on the spin-independent WIMP-nucleon interaction cross-section.
