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

William A. Ponce, Arnulfo Zepeda, Juan B. Flórez

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 min…
