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

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.
