Abstract Within the framework of the perturbative QCD approach utilizing factorization, we investigated the CP violation and branching ratios in the decay processes of and , where V denotes the three vector mesons , ω , and ϕ . During the and decay processes, we incorporated the mixing mechanism to describe the amplitudes of these quasi-two-body decays. Within the interference region of the three vector particles, we observed distinct changes in both CP violations and branching ratios. Furthermore, our study presents evidence for local CP violations and branching ratios that warrants further experimental investigation.
