Unitarized Chiral Perturbation Theory and the meson spectrum

In this talk we briefly review how the unitarization of Chiral Perturbation Theory with dispersion relations can successfully describe the meson- meson scattering data and generate light resonances, whose mass, width and nature can be related to QCD parameters like quark masses and the number of col...
