Description

A precise understanding of WIMP discovery limits is indeed required for a correct interpretation of forthcoming data from multi-ton dark matter direct detection experiments. In this talk we will reconsider the discovery limit of multi-ton direct detection dark matter experiments in the light of recent measurements of the coherent elastic neutrino-nucleus scattering process by the COHERENT experiment. We will further comment about the impact of subleading nuclear form factor uncertainties, weak mixing angle uncertainties and new physics effects on the neutrino floor. Finally, to quantify the impact of new physics effects in the neutrino background, we revisit WIMP discovery limits assuming light vector and scalar mediators as well as neutrino magnetic moments/transitions.
