The resonance ƒ;0(1500): Is it a scalar glueball?

The ratios of the partial widths for the decay of a glueball into two pseudoscalar mesons are calculated under the assumption that the production of light quark pairs (uu, dd, ss) in soft gluon-induced reactions goes on within universal symmetry breaking. The parameter of the violation of flavour symmetry is fixed by the central hadron production data in high energy hadron collisions and/or by the ratios of radiative decay amplitudes JΨ → γηγη′ and JΨ → γφφγωω. The ratios of the coupling constants glueball → ππ, KK, ηη, ηη′ which are calculated with this parameter coincide reasonably with those of ƒ;0(1500), supporting the idea about the glueball nature of ƒ;0(1500).
