A Light Mediator Relating Neutrino Reactions

Abstract

The extension of the standard model with a multiplicative $U(1{)}_R$ factor is consistent with a light vector boson. In its simplest realization, only right-handed particles carry charges of the new group. In this model, there is a residual ${\tau }_{3R}$ symmetry and one new coupling constant which correlates neutrino interactions. We compute new contributions to antineutrino$-$electron scattering and coherent scattering on nuclei, and compare them with the XENON1T result.
