    Abstract

    We develop tools to determine the gluonic content of a resonance of known mass, width, and JPC from its branching fraction in radiative quarkonium decays and production cross section in γγ collisions. We test the procedures by applying them to known qq̄ mesons, then analyze four leading glueball candidates. We identify inconsistencies in data for J/ψ→γf0(1500) and J/ψ→γfj(1710) whose resolution can quantify their glueball status. When Γ(f0(1500)→γγ) and Γ(fj(1710)→γγ) are known, the nn̄,ss̄,gg mixing angles can be determined. The enigmatic situation in the 1400-1500 MeV region of the isosinglet 0-+ sector is discussed.
