Is f0(1500) a scalar glueball?

Following the discovery of two new scalar mesons f0(1370) and f0(1500) at the Low Energy Antiproton Ring at CERN, we argue that the observed properties of this pair are incompatible with them both being QQ-bar mesons. We show instead that f0(1500) is compatible with the ground state glueball expecte...

description Following the discovery of two new scalar mesons f0(1370) and f0(1500) at the Low Energy Antiproton Ring at CERN, we argue that the observed properties of this pair are incompatible with them both being QQ-bar mesons. We show instead that f0(1500) is compatible with the ground state glueball expected around 1500 MeV mixed with the nearby states of the 0++QQ-bar nonet. Tests of this hypothesis include the prediction of a further scalar state f'0(1500–1800) which couples strongly to KK-bar, eta eta , and eta eta '. Signatures for a possible tensor glueball at ~2 GeV are also considered.
