Evidence for the Observation of a Glueball

Abstract

I briefly review lattice QCD, the valence (quenched) approximation, and the application of both to the determination of the mass and two-body decay couplings of the lightest scalar glueball. Results in agreement with the observed properties of $f_J(1710)$ strongly suggest this resonance is largely a scalar glueball.
