Within the neutrino-fog: CEvNS as precision Standard Model test and new physics probe
The recent observation of coherent elastic neutrino-nucleus scattering (CEvNS) from solar 8B neutrinos in dark matter direct detection experiments has inaugurated the neutrino-fog era, highlighting the extended potential of these experiments as precision neutrino observatories. These measurements provide new opportunities to test Standard Model predictions and to probe physics beyond it, in complementarity with dedicated neutrino facilities. In this talk I present a combined analysis of nuclear recoil data from XENONnT, PandaX-4T, and
LUX-ZEPLIN experiments to extract information on the solar 8B neutrino flux normalization and on the weak mixing angle at low-momentum transfer. Additionally, I will comment the derived constraints on new physics scenarios involving light and heavy vector mediators.
