Abstract

In perturbative QCD approach, based on the first order of isospin symmetry breaking, we study the direct CP violation in the decay of B¯s0ρωK0π+πK0. An interesting mechanism is applied to enlarge the CP violating asymmetry involving the charge symmetry breaking between ρ and ω. We find that the CP violation is large by the ρω mixing mechanism when the invariant masses of the π+π pairs are in the vicinity of the ω resonance. For the decay process of B¯s0ρωK0π+πK0, the maximum CP violation can reach 59.12%. Furthermore, taking ρω mixing into account, we calculate the branching ratio for B¯s0ρωK0. We also discuss the possibility of observing the predicted CP violation asymmetry at the LHC.
