Description
Tens of MeV neutrinos, e.g. from the stopped pion or core-collapse supernova sources, scatter off the target nucleus in the detector either via a coherent elastic or the inelastic process and allow the study of a variety of SM and BSM processes. The precision of the coherent elastic neutrino nucleus scattering (CEvNS) process, where the scattered nucleus remains in its ground state, is limited by the precision with which the underlying weak form factor of the nucleus is known. Fully exploring the potential of CEvNS experiments requires a detailed description of underlying nuclear structure embedded in the weak form factor. Additionally, CEvNS experiments at stopped pion sources are also powerful avenues to measure inelastic cross sections, where neutrino excites the target nucleus to low-lying nuclear states and is subject to more detailed underlying nuclear structure and dynamics, that are vital in constraining supernova physics prospects of future neutrino experiments. In this talk, I will present an overview of CEvNS and inelastic neutrino-nucleus interactions in the tens of MeV region, constraining those are vital in disentangling beyond the Standard Model physics signals from the SM signals in neutrino experiments.
