  "abstract": "We report on a blinded search for dark matter (DM) using ionization-only (S2-only) signals in XENONnT with a total exposure of 7.83 Tonne-year over 579 days in three science runs. Dedicated background suppression techniques and the first complete S2-only background model in XENONnT provide sensitivity to nuclear recoils of [0.5,5.0] keV_{nr} and electronic recoils of [0.04,0.7] keV_{ee}. No significant excess over the expected background is observed, and we set 90% confidence level upper limits on spin-independent DM-nucleon and spin-dependent DM-neutron scattering for DM masses between 3 and 8 GeV/c^{2}, as well as on DM-electron scattering, axionlike particles, and dark photons, improving on previous constraints. For spin-independent DM-nucleon scattering, we exclude cross sections above 6.0×10^{-45} cm^{2} at a DM mass of 5 GeV/c^{2}, pushing the XENONnT sensitivity closer to the region where coherent elastic neutrino-nucleus scattering becomes an irreducible background.",
