In the three-state mixing framework, considering the possible glueball components of \(\eta\) and \(\eta^\prime\), 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 \(\eta\) and \(\eta^\prime\). Furthermore, we discuss some properties of the mass matrix describing the mixing of the isoscalar scalar mesons.
