摘要：

Form the observation that there is a three-fold hierarchy of quark and lepton masses we are led to impose a discrete symmetry on the lagrangian. As a consequence, two quark masses and all mixing angles are predicted with the following results: (i) tan θc = (md/ms) 1 2; (ii) mb is predicted correctly; (iii) mt is predicted to be ∼ 20 GeV; (iv) the relation me/mμ ≈ mu/mc emerges automatically; (v) a heavy meson containing a b quark is predicted to decay into charmed particles with a lifetime of ∼ 10-11 s; (vi) the magnitude of CP violation in KL → 2π automatically is O(10-3). © 1979.
