Abstract
We investigate CP violation in the decay process by considering the interference effects of , , and within the framework of the perturbative QCD method (P refers to π, K, η, and pseudoscalar mesons). We analyze the mixings of , , and and provide the amplitudes of the quasi-two-body decay processes. The CP violation for the 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.
