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=\fracm_\ensuremathμ3, m_b=m_\ensuremathτ in a new way and is easily consistent with values of m_t suggested by MSSM fits to CERN LEP data.
