Split Left-Right Symmetry and Scotogenic Quark and Lepton Masses
Abstract
A model of split left-right symmetry is proposed, where the first family of quarks and leptons transforms under SU(2)R but the heavier two families do not. The Higgs scalar sector consists only of an SU(2)L doublet and an SU(2)R doublet. The u,d quarks and the electron, as well as the neutrinos, are massless at tree level, but become massive radiatively through their interactions with a simple dark sector. Verifiable consequences include Z' and Higgs properties, neutrino mixing and rare decays, etc.
