Abstract: (arXiv)
We compute from lattice QCD in the valence (quenched) approximation the partial decay widths of the lightest scalar glueball to pairs of pseudoscalar quark-antiquark states. These predictions and values obtained earlier for the scalar glueball's mass are in good agreement with the observed properties of fJ(1710)f_J(1710) and inconsistent with all other observed meson resonances.
