Abstract: (arXiv)
Following the discovery of two new scalar mesons, and 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 is compatible with the ground state glueball expected around 1500 MeV mixed with the nearby states of the nonet. Tests of this hypothesis include the prediction of a further scalar state, which couples strongly to , and . Signatures for a possible tensor glueball at 2 GeV are also considered.- bibliography
