Description
Coherent elastic neutrino–nucleus scattering (CEvNS) is a neutral-current weak interaction in which a neutrino scatters coherently from an entire nucleus at low momentum transfer. The coherent enhancement of the nuclear weak charge yields a cross section that scales approximately as N^2, while the associated nuclear recoils are typically at the keV or sub-keV scale. The Standard-Model prediction is theoretically well constrained, subject to nuclear-form-factor and detector-response uncertainties, making CEvNS a sensitive probe of electroweak interactions and possible physics beyond the Standard Model.
This talk will review the experimental landscape of CEvNS, including measurements with neutrinos from stopped-pion decay and nuclear reactors, as well as the emerging sensitivity to solar-neutrino CEvNS in dark-matter detectors. The current experimental program and prospects for future CEvNS measurements will also be briefly discussed. Finally, the talk will consider how CEvNS and stopped-pion neutrino facilities can improve the interpretation of future supernova-neutrino observations through measurements of neutrino interaction cross sections at supernova-relevant energies.
