Abstract

Rates and CP asymmetries of the non-leptonic two-body decay of B c are calculated based on the low energy effective Hamiltonian. We concentrate on such b quark decays of the processes with 0− and 1− S-wave particles and/or 0+ and 1+ P-wave particles in the final states. The Salpeter method, which is the relativistic instantaneous approximation of the original Bethe-Salpeter equation, is used to derive hadron transition matrix elements. Based on the calculation, it is found that the best decay channels to observe CP violation are B c − → η c + D −(D 0 *−), which need about ∼ 107 B c events in experiment. Decays to η c + D *−(D s −), h c  + D −(D *−)(D 0 *−), J/Ψ + D ∗− are also hopeful channels.
