The scalar quarkonium spectrum and quarkonium-glueball mixing
Abstract
We evaluate the valence approximation to the mass of scalar quarkonium and to the mixing energy between scalar quarkonium and the lightest scalar glueball for a range of different lattice sizes and quark masses. Our results support the identification of f0(1710) as the lightest scalar glueball.
