摘要：

We study a coset-space unification model for families based on E-7/SU(5) x U(1)(3). We find that qualitative structure of quark and lepton mass matrices in this model describes very well the observation. We stress, in particular, that the large mixing angle, sin(2)2 theta(v mu v tau) similar or equal to 1, required for the atmospheric neutrino oscillation reported by the SuperKamiokande collaboration, is naturally obtained, which is a consequence of unparallel family structure in the present coset-space unification.
