The XENONnT experiment, located at the INFN Laboratori Nazionali del Gran Sasso in Italy, is designed to detect a dark matter candidate—Weakly Interacting Massive Particles (WIMPs)—by observing their interactions with xenon nuclei. A particularly intriguing aspect of this search is the potential for coherent elastic neutrino-nucleus scattering (CEvNS) between Boron-8 neutrinos and xenon nuclei, which produces a signal similar to that of WIMPs. In this seminar, I will present the analysis that led to the first measurement of solar neutrinos via CEvNS, based on data from XENONnT's first 3.5 ty exposure.
