A chiral model for sterile neutrino
arXiv:2109.07828 · doi:10.1007/JHEP12(2021)075
Abstract
A model, which extends the standard model with a new chiral U(1) gauge symmetry sector, for the eV-mass sterile neutrino is constructed. It is basically fixed by anomaly free conditions. The lightness of the sterile neutrino has a natural explanation. As a by product, this model provides a WIMP-like dark matter candidate.
