Coupling Constants for Scalar Glueball Decay
J. Sexton, A. Vaccarino, D. Weingarten
Abstract
We evaluate the partial decay widths of the lightest scalar glueball to pairs of pseudoscalar quark-antiquark states. The calculation is done in the valence (quenched) approximation on a 163 24 lattice at β= 5.7. These predictions and values obtained earlier for the infinite volume continuum limit of the scalar glueball's mass are in good agreement with the observed properties of fJ(1710) and inconsistent with all other observed meson resonances.
