Abstract:

Coherent elastic neutrino-nucleus scattering (CEνNS) has the largest predicted cross-section of all low-energy neutrino interactions. However, the only experimental signature of CEνNS is a low-energy nuclear recoil which made its detection challenging. In this talk, after a brief introduction on the observation of CEνNS at Spallation Neutron Source with CsI and Argon detectors by the COHERENT experiment, and the recent suggestive evidence of CEνNS from reactor neutrinos, I will mainly discuss the implication of the CEνNS detection as a novel tool to study important properties of the nuclear structure, neutrino interactions, and new physics beyond the Standard Model. The prospect of solar neutrino CEνNS detection in future dark matter direct detection experiments will also be presented.
