The primary goal of the XENONnT experiment is the direct detection of Weakly Interacting Massive Particles (WIMPs), with a projected sensitivity improvement of an order of magnitude over XENON1T. In this talk, I will present recent results from searches for light dark matter and solar neutrinos using the scintillation-ionization channel and the ionization-only channel with a lowered detection threshold. Together, these complementary analyses set competitive constraints on dark matter–nucleon and dark matter–electron scattering cross sections. In the relevant mass range, the sensitivity approaches the so-called neutrino fog, where coherent neutrino scattering constitutes an irreducible background that can mimic light dark matter interactions.
