Properties of the scalar mesons f(0)(1370), f(0)(1500) and f(0)(1710)

In the three-state mixing framework, considering the possible glueball comp onents of eta and eta ' we investigate the hadronic decays of f(o)(1370), f (o)(1500) and f(o)(1710) into two pseudoscalar mesons. The quarkonia-glueba ll content of the three states is: determined from a fit to the new data pr esented by the WA102 Collaboration. The find that these data are insensitiv e to the possible glueball components of eta and eta ' Furthermore. we disc uss some properties of the mass matrix describing the mixing of tile isosca lar scalar mesons.
