Is U(1)H a Good Family Symmetry?
William A. Ponce, Arnulfo Zepeda, Jesús M. Mira
Abstract
We analyze U(1)H as a horizontal symmetry and its possibilities to explain the known elementary-fermion masses. We find that only two candidates, in the context of SU(3)c(2)L(1)Y(1)H nonsupersymmetric, are able to fit the experimental result mb<<mt.
