Dynamical Symmetry Breaking and Fermion Mass Hierarchy in the Scale-Invariant 3-3-1 Model

Alex G. Dias, Julio Leite, B. L. Sánchez-Vega +1

We propose an extension of the Standard Model (SM) based on the $SU(3{)}_C\otimes SU(3{)}_L\otimes U(1{)}_X$ (3-3-1) gauge symmetry and scale invariance. Maintaining the main features of…
