A New Model for Fermion Masses in Supersymmetric Grand Unified Theories

Abstract

We present a simple model for fermion mass matrices and quark mixing in the context of supersymmetric grand unified theories and show its agreement with experiment. Our model realizes the GUT mass relations $m_d=3m_e$, $m_s=m_{\mu }/3$, $m_b=m_{\tau }$ in a new way and is easily consistent with values of $m_t$ suggested by MSSM fits to LEP data.
