Description
The XENONnT experiment operates a liquid xenon time projection chamber at the INFN Laboratori Nazionali del Gran Sasso, designed to search for weakly interacting massive particles (WIMPs). Its ultra-low background rate and low energy threshold, achieved to maximize WIMP sensitivity, also enable the study of other rare processes.
In this talk, I will present the latest results from XENONnT. A search for spin-independent WIMP–nucleon interactions based on a 3.1 tonne-year exposure sets new constraints for WIMP masses above $10 \text{ GeV}/c^2 $. In addition, recent results on coherent elastic neutrino–nucleus scattering (CEvNS) from solar $^{8}\text{B}$ neutrinos demonstrate sensitivity to this low-energy signal and probe the neutrino background relevant for future dark matter searches.
