Abstract：
In the framework of factorization, we study direct CPviolation in the decays of B _(s)→J/ψP(V) (P(V) refer to the pseudoscalar (vector) meson). The CPviolation depends strongly on Cabibbo-Kobayashi- Maskawa (CKM) matrix elements and the effective parameter, N _c. The recent experimental data for the branching ratios of B _(s)→J/ψP(V) are accurate enough and we can give a strong constraint on the range of N _c. We nd that the CPviolating asymmetry is consistent with the available experiment values for the b→d transition, and a little smaller than the b→s transition. We also predict the CPviolation of other decay channels for B _(s)→J/ψP(V). We expect our results can give valuable guidance for experiments.
