Properties of the scalar mesons f_0(1370), f_0(1500) and f_0(1710)

摘要

In the three-state mixing framework, considering the possible glueball components of η and η', we investigate the hadronic decays of f_0(1370), f_0(1500) and f_0(1710) into two pseudoscalar mesons. The quarkonia-glueball content of the three states is determined from a fit to the new data presented by the WA102 Collaboration. We find that these data are insensitive to the possible glueball components of η and η'n. Furthermore, we discuss some properties of the mass matrix describing the mixing of the isoscalar scalar mesons.
