Description
The recent observation of coherent elastic neutrino–nucleus scattering (CEvNS) from solar $^8$B neutrinos in dark matter direct detection experiments marks the beginning of the so-called neutrino fog era and further establishes these detectors as powerful low-energy neutrino observatories. Recent results from XENONnT, PandaX-4T, and LUX-ZEPLIN open new opportunities to test Standard Model predictions and search for new physics, in complementarity with dedicated neutrino experiments. In this talk, I will discuss the phenomenological implications of these measurements, including the extraction of the weak mixing angle at low momentum transfer and constraints on new interactions mediated by heavy or light particles. I will also examine the implications of these results for dark matter direct detection, particularly regarding the characterization of the neutrino fog and its impact on future discovery limits.
