Abstract

We consider the hadronic description of the B-d(0) --> pi (+)pi (-) decay,with the aim to investigate the strong phases generated by the final stateinteractions. The derivation of the dispersion relations using the Lehmann-Symanzik-Zimmermann formalism and the Goldberger-Treiman method to includeinelastic effects in the spectral function are presented. We discuss the problem of quark hadron duality and estimate in the hadronic formalism the corrections to the factorized amplitude in the heavy quark limit.
