2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/46260I 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.12 pages of Latex, 5 PostScript figures, uses sprocl.sty which is included, invited talk at Continuous Advances in QCD, '96High Energy Physics - Phenomenologytext
