Coupling constants for scalar glueball decay
1996
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 16 3 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 ƒ J (1710) and inconsistent with all other observed meson resonances.
