Numerical evidence for the observation of a scalar glueball

Abstract

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) and inconsistent with all other observed meson resonances. © 1995 The American Physical Society.
