Universal Scotogenic Fermion Masses in Left-Right Gauge Model

Abstract

In the conventional left-right gauge model, if the Higgs scalar sector consists only of an $SU(2{)}_L$ doublet and an $SU(2{)}_R$ doublet, fermion masses are zero at tree level. There have been many studies on how they would become massive. With the help of a dark sector with $U(1{)}_D$ gauge symmetry, it is shown how all standard-model fermions may acquire realistic masses radiatively, including that of the top quark. In this context, the particle content of the model also implies the automatic conservation of baryon number $B$ and lepton number $L$ as in the standard model. Observable anomalous Higgs couplings are predicted.
