Search for Light Dark Matter with XENONnT

The main goal of the XENONnT detector is the direct detection of Weakly Interacting Massive Particles (WIMPs), aiming to improve the sensitivity by one order of magnitude than XENON1T. In this talk, I'll present a search for dark matter with a mass [3, 12] GeV/c2 using an exposure of 3.51 tonne × year of XENONnT data. In the considered mass range, the DM sensitivity approaches the 'neutrino fog', the limitation where neutrinos produce a signal that is indistinguishable from that of light DM-xenon nucleus scattering.
