The Coherent elastic neutrino-nucleus scattering (CEvNS) was first predicted in 1974. It is the dominant neutrino scattering process below 100MeV. Though CEvNS has the most significant cross-section of low-energy neutrino scatterings, it has eluded detection for over 40 years due to technical difficulties in building low-energy thresholds and low background detectors. In 2017 and 2021, the...

In the Standard Model, neutrinos are predicted to have zero mass. However, the discovery of neutrino oscillations has proven that neutrinos possess mass, making neutrino research a promising avenue for exploring Beyond the Standard Model (BSM) physics.
