Neutrino nonstandard interactions: Confronting COHERENT and LHC data

Abstract

We study the complementarity between COHERENT and LHC searches in testing neutrino nonstandard interactions (NSIs) through the completion of the effective field theory approach within a $Z^{\prime }$ simplified model. Our results show that LHC bounds are strongly dependent on the $Z^{\prime }$ mass, with relatively large masses excluding regions in the parameter space that are allowed by COHERENT data and its future expectations. We demonstrate that the combination of low- and high-energy experiments results in a viable approach to break NSI degeneracies within the context of simplified models.
