COUPLING-CONSTANTS FOR SCALAR GLUEBALL DECAY

We evaluate the partial decay widths of the lightest scalar glueball t o pairs of pseudoscalar quark-antiquark states. The calculation is don e in the valence (quenched) approximation on a 16(3) lattice at beta = 5.7. These predictions and values obtained earlier for the infinite v olume continuum limit of the scalar glueball's mass are in good agreem ent with the observed properties of f(J)(1710) and inconsistent with a ll other observed meson resonances.
