Phys. Rev. D 64, 117302 (2001) [4 pages]Model for fermion mass matrices and the origin of quark-lepton mass relationsReceived 3 July 2001; published 8 November 2001 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, a way in which approximate relations between quark and lepton mass matrices can be achieved without unified gauge theories is proposed. © 2001 The American Physical Society URL:
