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 →ηc + D-(D*-0 ), which need about ∼ 107 Bc events in experiment. Decays to ηc + D*-(D-s ), h c + D-(D*-)(D*- 0 ), J/ψ + D*- are also hopeful channels.
