Scalar Quarkonium and the Scalar Glueball

Abstract

Valence approximation glueball mass and decay calculations support the identification of $f_J(1710)$ as the lightest scalar glueball. An alternate glueball candidate is $f_0(1500)$. I present evidence for the identification of $f_0(1500)$ as $s\overline{s}$ quarkonium.
