  • xenon1t dark matter data Analysis Signal reconstruction calibration and event selection
    Physical Review D, 2019
    Co-Authors: E Aprile, J Aalbers, F Agostini, M Alfonsi, L Althueser, F D Amaro, V C Antochi, F Arneodo, L Baudis

    Abstract:

    The XENON1T experiment at the Laboratori Nazionali del Gran Sasso is the most sensitive direct detection experiment for dark matter in the form of weakly interacting particles (WIMPs) with masses above 6  GeV/c2 scattering off nuclei. The detector employs a dual-phase time projection chamber with 2.0 metric tons of liquid xenon in the target. A one metric ton×year exposure of science data was collected between October 2016 and February 2018. This article reports on the performance of the detector during this period and describes details of the data Analysis that led to the most stringent exclusion limits on various WIMP-nucleon interaction models to date. In particular, Signal reconstruction, event selection, and calibration of the detector response to nuclear and electronic recoils in XENON1T are discussed.

  • xenon1t dark matter data Analysis Signal and background models and statistical inference
    Physical Review D, 2019
    Co-Authors: E Aprile, L Baudis, J Aalbers, F Agostini, M Alfonsi, L Althueser, F D Amaro, V C Antochi, F Arneodo, B Bauermeister

    Abstract:

    The XENON1T experiment searches for dark matter particles through their scattering off xenon atoms in a 2 metric ton liquid xenon target. The detector is a dual-phase time projection chamber, which measures simultaneously the scintillation and ionization Signals produced by interactions in target volume, to reconstruct energy and position, as well as the type of the interaction. The background rate in the central volume of XENON1T detector is the lowest achieved so far with a liquid xenon-based direct detection experiment. In this work we describe the response model of the detector, the background and Signal models, and the statistical inference procedures used in the dark matter searches with a 1  metric ton×year exposure of XENON1T data, that leads to the best limit to date on WIMP-nucleon spin-independent elastic scatter cross section for WIMP masses above 6  GeV/c2.
