Description
Scalar mesons play important roles in low-energy QCD and are known to be nontrivial states in hadron spectroscopy. Within the context of a generalized linear sigma model that includes two nonets of scalar mesons (a two-quark nonet and a four-quark nonet) and two nonets of pseudoscalar mesons (a two-quark nonet and a four-quark nonet) a collective description of scalar and pseudoscalar mesons below and above 1 GeV is studied. In this study, the quark contents of these states are probed and estimates on their quark components are extracted. Within the same framework various low-energy scatterings (such as pi pi scattering and pi K scattering) as well as decays such as eta prime to eta pi pi, are also investigated and the properties of scalar mesons are probed. This presentation will provide an overview of these investigations and will discuss future directions.
