Description

As direct detection experiments approach sensitivities where neutrinos become an irreducible background due to their interactions via coherent elastic neutrino-nucleus scattering (CEvNS), they pose a fundamental limitation in the search for Dark Matter. Given that CEvNS has only recently been observed, there remains significant room for new physics beyond the Standard Model (BSM) to alter the expected neutrino-induced recoil spectrum. In this talk, we examine how various BSM scenarios can modify the characteristics of the “neutrino fog”, and assess their implications for the interpretation of future Dark Matter signals.
