Unitarized Chiral Perturbation Theory and the meson spectrum

Jose R. Pelaez, C. Hanhart, J. Nebreda, G. Rios

英文摘要:

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.
