| contents | Dark matter direct detection experiments have become excellent low-energy neutrino detectors. We present a few novel ideas to probe Beyond the Standard Model physics from neutrinos at these experiments. First, we discuss signatures arising from the Migdal effect induced by solar neutrinos via Coherent Elastic Neutrino Nucleus Scatterings (CE$ν$NS) at the detector. Second, we discuss that placing a radioactive source near a liquid xenon detector may allow to observe the anapole moment of neutrinos expected in the Standard Model via neutrino-electron scattering. Third, we point out that neutrinos coupled to a light dark sector charged under a dark $U(1)'$ symmetry could feature enhanced electromagnetic properties at the loop-level. We further discuss the testability of this scenario with direct detection experiments sensitive to solar neutrinos. |
