CEvNS
CEvNS stands for Coherent Elastic Neutrino-Nucleus Scattering. It is a rare type of interaction between neutrinos and atomic nuclei. In this process, a neutrino interacts with an entire nucleus, causing it to recoil, while the neutrino itself remains largely unchanged and is scattered elastically. Unlike other neutrino interaction types that involve scattering off individual protons or neutrons, CEvNS scatters off the collective nuclear target.
This interaction was first predicted by Wolfgang Pauli in 1930 as a way to explain missing energy
CEvNS is sensitive to the weak mixing angle, a fundamental parameter in the Standard Model of particle
