A first step into the neutrino fog: first measurement of solar CEvNS with XENONnT

Tuesday 3 Dec 2024, 14:15 → 15:15 Europe/London

The XENONnT detector, located at Laboratori Nazionali del Gran Sasso, in  Italy, utilizes 5.9 tonnes of instrumented liquid xenon in the direct  search for weakly-interacting massive particle (WIMP) dark matter. Having  achieved unprecedented levels of target purity, it is sensitive to a  plethora of signals beyond WIMPs. This talk will present an overview of the experiment and its performance in the search of solar ^8B neutrino interactions via the so-called coherent elastic neutrino-nucleus  scattering (CEvNS) process. This analysis, pursued with a lower detection  threshold than the standard WIMP search, yielded the first-ever solar  CEvNS measurement, with a statistical significance of 2.7σ.
