Model for fermion mass matrices and the origin of quark-lepton symmetry

arXiv:hep-ph/0106286 · doi:10.1103/PhysRevD.64.117302

Abstract

Several phenomenological features of fermion masses and mixings can be accounted for by a simple model for fermion mass matrices, which suggests an underlying U(2) horizontal symmetry. In this context, it is also proposed how an approximate quark-lepton symmetry can be achieved without unified gauge theories.
