Abstract
The ratios of the partial widths for the decay of a glueball into two pseudoscalar mesons are calculated under the assumption that the produ ction of light quark pairs (u (u) over bar, d (d) over bar, s (s) over bar) in soft gluon-induced reactions goes on within universal symmetr y breaking. The parameter of the violation of flavour symmetry is fixe d by the central hadron production data in high energy hadron collisio ns and/or by the ratios of radiative decay amplitudes J/psi --> gamma eta/gamma eta' and J/psi --> gamma phi phi/gamma omega omega. The rati os of the coupling constants glueball --> pi pi, K (K) over bar, eta e ta, eta eta' which are calculated with this parameter coincide reasona bly with those of fo(1500), supporting the idea about the glueball nat ure of f0(1500).
