Abstract: (arXiv)
Following the discovery of two new scalar mesons, f0(1370)f_0(1370) and f0(1500)f_0(1500) at the Low Energy Antiproton Ring at CERN, we argue that the observed properties of this pair are incompatible with them both being \qqbar mesons. We show instead that f0(1500)f_0(1500) is compatible with the ground state glueball expected around 1500 MeV mixed with the nearby states of the 0++0^{++} QQˉQ\bar{Q} nonet. Tests of this hypothesis include the prediction of a further scalar state, f0(15001800)f_0'(1500 - 1800) which couples strongly to KKˉK\bar{K}, ηη\eta\eta and ηη\eta\eta'. Signatures for a possible tensor glueball at \sim 2 GeV are also considered.
