Description

The final state interaction (FSI) appears as mechanism to enhance the  CP asymmetry  in the neutral D decays in two pions and kaons, due to the strong coupling between the two channels [1]. Another manifestation of the hadronic FSI is in the solution of the helicity asymmetry puzzle in the charged B three-body decays into proton-antiproton and pion or kaon [2]. In this last case the consideration of the FSI, demands the analysis of the Faddeev-Bethe-Salpeter equations for the three-body decay to define the decay amplitudes.
