Isf0(1500) a scalar glueball?

Following the discovery of two new scalar mesons, $f_0(1370)$ and $f_0(1500)$at the Low Energy Antiproton Ring at CERN, we argue that the observedproperties of this pair are incompatible with them both being $\qqbar$ mesons.We show instead that $f_0(1500)$ is compatible with the ground state glueballexpected around 1500 MeV mixed with the nearby states of the $0^{++}$$Q\bar{Q}$ nonet. Tests of this hypothesis include the prediction of a furtherscalar state, $f_0'(1500 - 1800)$ which couples strongly to $K\bar{K}$,$\eta\eta$ and $\eta\eta'$. Signatures for a possible tensor glueball at $\sim$2 GeV are also considered.Comment: 11 figures; PS files or hard copy available from C Amsle
