Abstract
In the perturbative QCD approach, we study the direct violation in the decay of via isospin symmetry breaking. An interesting mechanism involving the charge symmetry violating between and is applied to enlarge the violating asymmetry. We find that the violation can be enhanced by the mixing mechanism when the invariant masses of the pairs are in the vicinity of the resonance. For the decay process of , the maximum violation can reach 5.98%. The possibility of detecting the violation is also presented.
