摘要：

This Letter accounts for the observed (i) enhancement of Γ(D0→K-K+)Γ(D0→K-π+) and (ii) suppression of Γ(D0→π-π+)Γ(D0→K-π+) relative to tan2θC in terms of (i) the ratio fKfπ of leptonic decay constants and (ii) different effective Cabibbo angles in noncharm and charm sectors. Strong new constraints on mixing angles in the six-quark model are implied. © 1979 The American Physical Society.
