Properties of Light Resonances from Unitarized Chiral Perturbation Theory:NcBehavior and Quark Mass Dependence

J. R. Peláez, J. Nebreda, G. Ríos
2010 Progress of Theoretical Physics Supplement  
We review the unitarization of Chiral Perturbation Theory with dispersion relations and how it describes meson-meson scattering data, generating light resonances whose mass, width and nature can be related to QCD parameters like quark masses and the number of colors.
