摘要：

The formula tan2Cmdms is derived from a continuous symmetry. Cabibbo universality is guaranteed in a natural way. All weak mixing angles are determined in terms of quark masses. The b quark is predicted to decay mainly to the u quark, and the lifetime of the associated mesons is 10-10-10-11 sec. We argue that this additional symmetry is (essentially) the only one which can be added to the standard SUc(3)SU(2)U(1) model without generating anomalies. © 1979 The American Physical Society.
