Resumen
We propose a renormalizable theory based on the SU(3) C× SU(3) L× U(1) X gauge symmetry, supplemented by the spontaneously broken U(1)Lg global lepton number symmetry and the S3× Z2 discrete group, which successfully describes the observed SM fermion mass and mixing hierarchy. In our model the top and exotic quarks get tree level masses, whereas the bottom, charm and strange quarks as well as the tau and muon leptons obtain their masses from a tree level Universal seesaw mechanism thanks to their mixing with charged exotic vector like fermions. The masses for the first generation SM charged fermions are generated from a radiative seesaw mechanism at one loop level. The light active neutrino masses are produced from a loop level radiative seesaw mechanism. Our model successfully accommodates the experimental values for electron and muon anomalous magnetic dipole moments. © 2021, The Author(s).
