Description
The recent detection of coherent elastic neutrino-nucleus elastic scattering (CE$\nu$NS) by the COHERENT experiment has enabled new area of neutrino physics. Apart from neutrino experiments using the stop pion source, the CE$\nu$NS measurement may be complemented by reactor experiments. We studied this complementarity between the accelerator and reactor CE$\nu$NS experiments for constraining new physics in the form of non-standard neutrino interactions (NSI). Previous studies that have constrained NSI with both oscillation and scattering experiments typically vary one or two NSI parameters when fitting to a given data set. In this talk, however, we consider four flavor-diagonal up and down-type NSI parameters. We demonstrated that a simultaneous analysis with reactor and accelerator experiments, for several different target materials, breaks a degeneracy between up and down flavor diagonal NSI terms that has persisted with neutrino experiments.
