摘　　要：We investigate CP violation in the decay process B_(s)→ϕ(ρ,ω)P→K^(+)K^(-)P by considering the interference effects ofϕ→K^(+)K^(-),ρ→K^(+)K^(-),andω→K^(+)K^(-)within the framework of the perturbative QCD method(P refers toπ,K,η,andη′pseudoscalar mesons).We analyze the mixings ofϕ−ρ^(0),ϕ−ω,andω−ρ0 and provide the amplitudes of the quasi-two-body decay processes.The CP violation for the B_(s)→K^(+)K^(-)P decay process is obvious in the ranges of the three vector meson interferences.Meanwhile,the localized CP violation can be found to compare with the experimental results from the three-body decay process at the LHC in the near future.
