Title: Latest solar neutrino and WIMP search results from the XENONnT experiment"

Place: Seminar Room A
Abstract:
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. Another 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 analyses of solar neutrino CEvNS and WIMP based on data from XENONnT's first two science runs.
