Abstract

We take up again the study of the mass spectrum of the quark sector in a model with gauge symmetry SU(3)c⊠- SU(3)L⊠- U(1)X(331). In a special type II-like 3-3-1 model, we obtain specific zero-texture mass matrices for the quarks which predict four massless quarks (u,c,d,s) and two massive quarks (b,t) at the electroweak scale (∼GeV). By considering the mixing between the standard model quarks and new exotic quarks at large scales predicted by the model, we find that a third quark (associated to the charm quark) acquires a mass. The remaining light quarks (u,d,s) get small masses (∼MeV) via radiative corrections. © 2013 American Physical Society.
