Mass Scales and Stability of the Proton in [SU(6)]${}^3\times$Z${}_3$

Abstract

We proof that the proton is stable in the left-right symmetric gauge model [SU(6)]${}^3\times$Z${}_3$, which unifies nongravitational forces with flavors, broken spontaneously by a minimal set of Higgs Fields and Vacuum Expectation Values down to SU(3)${}_c\otimes$U(1)${}_{EM}$\hspace{0.2cm} . We also compute the evolution of the gauge coupling constants and show how agreement with precision data can be obtained.
