Is U(1)$_H$ a Good Family Symmetry?

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

We analyze U(1)H_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_c\otimesSU(2)L_L\otimesU(1)Y_Y\otimesU(1)H_H nonsupersymmetric, are able to fit the experimental result mb<<_b<<mt_t.
