dc.description.abstract
We study scalar, pseudoscalar, vector, and axial-vector mesons with non-strange and strange quantum numbers in the framework of a linear sigma model with global chiral U(Nf)L×U(Nf)R symmetry. We perform a global fit of meson masses, decay widths, as well as decay amplitudes. The quality of the fit is, for a hadronic model that does not consider isospin-breaking effects, surprisingly good. We also investigate the question whether the scalar \bar q-q states lie below or above 1 GeV and find the scalar states above 1 GeV to be preferred as \barq-q states. Additionally, we also describe the axial-vector resonances as \bar q-q states.
