Probing exotic neutral current interactions with coherent elastic neutrino-nucleus scattering

Abstract

: The exotic neutral current introduces new interactions beyond standard model (BSM) which consist of all possible four-fermion nonderivative Lorentz structures: scalar (S), pseudoscalar (P), vector (V), axial-vector (A), and tensor (T). In this work, we investigate the prediction of this model via the coherent elastic neutrino-nucleus scattering (CE ν NS). The differential cross section spectrum of CE ν NS for three nuclei in regards to experiment advancement are calculated in the framework of this model independent proposal using recent obtained bound. We present the ratio of this exotic model with the SM for various threshold energies. Significant bound is shown lie in the lower threshold case. The contributions from exotic neutral current interactions can considerably increase the rate of production relative to the SM case.
