Abstract
We consider the CP-violating asymmetry betweenB0→f and\(\overline {B^0 } \)→f in the case thatf is a CP-eigenstate containing no charmed quarks. The asymmetry is assumed to arise as a result of mixing with other channelsf′ having the same quantum numbers but containing ac\(\bar c\) pair. Inelastic unitarity is implemented by means of the K-Matrix formalism, in which the constraints of CPT are manifestly satisfied. The formalism is applied to a hypothetical two-channel problemB0→M\(\bar M\),M′\(\bar M\)′, and then to a realistic four-channel situationB0→π+π−,π0π0,D+D−,D0\(\bar D\)0. Asymmetries and branching ratios are estimated for the decaysB0→π+π−,π0π0.
