Radiative Left-Right Dirac Neutrino Mass
arXiv:1707.07698 · doi:10.1016/j.physletb.2017.08.071
Abstract
We consider the conventional left-right gauge extension of the standard model of quarks and leptons without a scalar bidoublet. We study systematically how one-loop radiative Dirac neutrino masses may be obtained. In addition to two well-known cases from almost 30 years ago, we find two new scenarios with verifiable predictions.
