I thank the organization staff, and particularly E. Ribeiro, for creating such a nice working environment and offering me the chance to participate in this wonderful Conference. | |
| dc.description.abstract | Dispersive approaches provide model independent description of meson-meson scattering. We first review here the use of dispersion relations to obtain a model independent unitarization of Chiral Perturbation Theory amplitudes, that establish the existence of light scalar mesons and whose leading 1/N_c behavior suggest they ahve a non q q̅ dominant component. We also review the forward dispersion relation checks on conflicting experimental data and the resulting very precise pi pi scattering scattering amplitudes. | |
