Abstract: We suggest a rigorous generalization of the pseudoscalar mesons mixingdescription in SU3 basis. It is shown that the appearance of extra massivestate nicknamed in the paper as glueball is unavoidable in any scheme with morethan one angle. In this framework we develop the dispersive approach to Abelianaxial anomaly of isoscalar non-singlet current. Combining it with the analysisof experimental data of charmonium radiative decays ratio we get the number ofquite strict constraints for mixing parameters. Our analysis favors the equalvalues of axial currents coupling constants which may be considered as amanifestation of SU3 symmetry and possible violation of chiral symmetry basedpredictions.
