Abandoning Exact SU(3) in Coupled-Channel Final-State Interactions Through Reggeon Exchange for B→ππ K K-bar
Description
For weak decays B0d → ππ and K K-bar the effects of SU(3) breaking in coupled-channel final-state interaction effects are discussed in a Regge framework. It is shown that SU(3) breaking in the inelastic final-state transitions dramatically affects the phases of the isospin I = 0, 1, 2 amplitudes in the B0d decays. The effect of the singlet penguin diagram on these phases is studied. Furthermore, on the example of the B0d → ππ decays, the dependence of CP asymmetries on the size of penguin amplitude is analyzed. (author)
