Direct CP violation in B(s)→J/ψP(V)

  • In the framework of factorization, we study direct CP violation in the decays of B(s)→J/ψP(V) (P(V) refer to the pseudoscalar (vector) meson). The CP violation depends strongly on Cabibbo-Kobayashi- Maskawa (CKM) matrix elements and the effective parameter, Nc. 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 Nc. We nd that the CP violating 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 CP violation of other decay channels for B(s)→J/ψP(V). We expect our results can give valuable guidance for experiments.

Direct CP violation in B(s)→J/ψP(V)

    Corresponding author: GUO Xin-Heng,

Abstract: In the framework of factorization, we study direct CP violation in the decays of B(s)→J/ψP(V) (P(V) refer to the pseudoscalar (vector) meson). The CP violation depends strongly on Cabibbo-Kobayashi- Maskawa (CKM) matrix elements and the effective parameter, Nc. 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 Nc. We nd that the CP violating 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 CP violation of other decay channels for B(s)→J/ψP(V). We expect our results can give valuable guidance for experiments.
