摘要：

Large CP-violation effects can occur for time-evolved B0 decays into definite CP eigenstates. The rates into these unique CP eigenmodes are tiny. This article advocates the use of many additional modes that are not CP eigenstates because of mixtures of angular momenta. Naively, for those modes a partial and sometimes large cancellation of the CP asymmetry occurs. However, a detailed study of their angular correlations enables the projection onto definite CP eigenstates, and thus recovers the full CP asymmetry.
