Abstract
We study the low-energy spectra of light mesons in the framework of constituent quark models. Several interactions including chiral symmetry breaking and designed for the description of the nucleon-nucleon system and/or the baryon spectra are used. We find that chiral quark models only based on Goldstone boson exchanges are not able to provide a reasonable description of the light meson spectra. However, if they are supplemented with a color-spin term, like the one present in the one-gluon-exchange or instanton-induced potentials, they reproduce in a satisfactory manner the light meson spectra at the same time that they are able to explain the main features of the baryon spectra and the baryon-baryon interaction.
