Abstract: We study standard and non-standard neutrino signals in direct dark matter detection experiments. The next generation of dark matter detectors will be soon sensitive to solar neutrinos via coherent neutrino-nucleus scattering. In this work, we compare the nuclear recoil rates expected from neutrino scattering with weakly interacting massive particle (WIMP) signals and we show that the scattering of neutrinos is an irreducible background for direct dark matter searches. We explore the possibility that neutrino interactions are enhanced by new physics with light mediators. We emphasize that the neutrino floor can be raised in the case that new scalar and vector mediators exist. Finally, we show how on the one hand, direct dark matter searches can be useful to probe or set constraints in new physics beyond the Standard Model, but on the other hand, their signatures could also be confused with dark matter signals.
