Abstract
The physical state of -- mesons can be mixed by the unitary matrix. The decay processes of and are from the isospin symmetry breaking. The , and interferences lead to resonance contribution to produce the strong phases. The asymmetry is considered from above isospin symmetry breaking due to the new strong phase for the first order. It has been found the asymmetry can be enhanced greatly for the decay process of when the invariant masses of the pairs are in the area around the resonance range and the resonance range in perturbative QCD. We also discuss the possibility to search the predicted violation at the LHC.
