Status of low energy electron-neutrino inelastic charged-current scattering on argon in CENNS-10

Measurement of the neutrino flux from the next galactic stellar core-collapse will usher in a new era for both astrophysics and particle physics. To enable the future Deep Underground Neutrino Experiment's measurement of the electron-neutrino component of a core-collapse, the low energy electron-neutrino inelastic charged-current scattering cross section on argon must be measured. The COHERENT collaboration will use neutrinos produced from pion decay at rest at the Spallation Neutron Source at Oak Ridge National Laboratory to measure this interaction. COHERENT has completed data taking with CENNS-10, a 24 kg single-phase liquid argon detector that measured coherent elastic neutrino nucleus scattering (CEvNS) on argon for the first time in 2021. An upgraded, tonne-scale liquid argon detector dubbed COH-Ar-750 is currently under construction with the goal of a precision CEvNS measurement as well as a precision measurement of the electron-neutrino inelastic charged-current scattering cross section on argon. The charged-current scattering search in CENNS-10 in preparation for COH-Ar-750 will be discussed.
