| Abstract: |
XENONnT is a direct dark matter search experiment located deep underground at the INFN Laboratori Nazionali del Gran Sasso in Italy. Designed to be sensitive to rare interactions of potential dark matter candidates, XENONnT’s central detector is a dual-phase time projection chamber with 5.9 tonnes of ultra-pure liquid xenon as an active target. > In addition, neutrinos from the Sun can interact with the nuclei of the xenon atoms in the XENONnT target via coherent elastic neutrino-nucleus scattering (CEvNS). This Standard Model process, first predicted in 1974, has been challenging due to the very low energy recoils and the elusive nature of neutrinos. XENONnT is the first experiment to measure CEvNS from neutrinos produced in the sun's core. In this talk, the analysis used data collected over two years, from July 7, 2021, to August 8, 2023, for a total exposure of approximately 3.5 tonne-years will be presented. |
