摘要：

By supplementing supersymmetric SO(10) with an anomalous U(1) flavor symmetry and additional 'matter' superfields carrying suitable U(1) charges, we explain the charged fermion mass hierarchies, the magnitudes of the CKM matrix elements, as well as the solar and atmospheric neutrino data. We stress bi-maximal vacuum neutrino mixings, and indicate how the small or large mixing angle MSW solution can be incorporated. The U(1) symmetry also implies that tau(p --> Rp)[SO(10] similar to (10-100).(tau p --> Kp)[minimal SU(5)]. (C) 2000 Published by Elsevier Science B.V.
