Radiative generation of light fermion masses in a $SU(3{)}_H$ horizontal symmetry model

Abstract

In a model with a gauge group $SU(3{)}_H\otimes G_{SM}$, where $SU(3{)}_H$ is a horizontal symmetry and $G_{SM}=SU(3{)}_C\otimes SU(2{)}_L\otimes U(1{)}_Y$ is the standard model, we propose a radiative mechanism of mass generation mediated by the $SU(3{)}_H$ gauge bosons for the light fermions, meanwhile the masses of the heaviest family are generated by the implementation of see-saw mechanisms with the introduction of vectorial fermions.
