Study the CP violation of the quasi-two-body decays of B meson with the a00(980) and f0(980) mixing

Abstract

In the framework of the QCD factorization approach, we study the localized CP violations of the B−→K−π+π−, B−→π−π+π−, B−→K−K+K−, B−→π−K+K−, B−→K−π0η and B−→π−π0η decays with and without the a00(980)−f0(980) mixing mechanism, respectively, and find that the localized CP violations can be enhanced by this mixing effect when the invariant masses of the ππ, KK and πη pairs in the final states are located around 980 MeV in the aforementioned decays. We suggest that the a00(980)−f0(980) mixing mechanism should be considered when studying the CP violation of the B or D meson decays theoretically and experimentally.
