Direct CP violation of three body decay processes from the resonance effect

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