Abstract

We investigate the CP violation in the decay process B_s → ϕ(ρ,ω) P → K⁺K^-P by considering the interference effects of ϕ→ K⁺K^-, ρ→ K⁺K^- and ω→ K⁺K^- within the framework of perturbative QCD method (P refers to π, K, η and η' pseudoscalar mesons, respectively). We analyse the mixings of ϕ-ρ⁰, ϕ-ω and ω-ρ⁰ and provide the amplitudes of the quasi-two-body decay processes. The CP violation for B_s → K⁺K^- P decay process is obvious at the ranges of the three vector mesons interferences. Meanwhile, the localised CP violation can be found for comparing with the experiment results from three-body decay process at the LHC in the near future.
