Coupled-Channel Final-State Interactions through Reggeon Exchange for D(B) --> ππ, K \bar{K}

Abstract

Coupled-channel final-state-interaction effects for D and B weak decays into ππand K \bar{K} are discussed in a Regge framework. It is found that the inclusion of coupled-channel effects significantly affects the results obtained previously in a quasi-elastic approximation. It is also shown that in the isospin I=0 channel the inelastic final-state transitions (ππ)_{I=0} --> (K \bar{K})_{I=0} dramatically influence the phase of the B^0 --> (K \bar{K})_{I=0} amplitude.
