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 $Z^{\prime }$ and Higgs properties, neutrino mixing and rare decays, etc.
