摘要
用振幅比值的方法，对末态为ＣＰ本征态的Ｂｄ０和Ｂｓ０介子衰变道可能的ＣＰ不对称性进行计算，并发现除了众所周知的Ｂｄ０→ψＫｓ外，Ｂｄ０→Ｄ＋Ｄ－也极有希望在１０７事例数附近观测到ＣＰ破坏．并讨论了计算结果的可靠性．
he CP violating effects in partial-decay-rate asymmetries of the Bd0 and Bs0 systems are reestimated with the method of amplitude ratio. We concentrate on those hadronic final states which are CP eigenstates. We find that for testing CP violations,except the well known Bd0→ψKs, the best decay is Bd0→D+D-, which needs, for 3σsignature, 2.2×107 bb pairs.
