Abstract
The pseudoscalar (PS) glueball is described with an account of the quark-gluon mixing and strict observation of the QCD local gauge and renormalization invariance. The lower limits on the mass and total width are established. The partial radiative decay widths and the PS-glueball production inJ/gY radiative decays are calculated. The consistency of the results with the η- and η′-meson data onJ/Ψ→PV decays is verified. On the basis of the results, the lower PS-glueball state may be identified with the upper iota state η(1490).
