Unitarized Chiral Perturbation Theory and the meson spectrum
arXiv:1003.0364 · doi:10.1063/1.3483311
Abstract
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 colors.
