Abstract
The contribution of high-mass states in the dispersion relation for decay amplitudes is considered. A finite dispersion relation (FDR) implemented by duality and finite-energy sum rules (FESR), is suggested as a useful tool for such calculations, and an application to the decay is done in some detail.
