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 state interactions. The derivation of the dispersion relations using the Lehmann- Symanzik-Zimmermann formalism and the Goldberger-Treiman method to include inelastic effects in the spectral function are presented. We discuss the pr oblem of quark hadron duality and estimate in the hadronic formalism the co rrections to the factorized amplitude in the heavy quark limit.
