Is f0(1500) a scalar glueball?

چکیده
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 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 QQ̄ nonet. Tests of this hypothesis include the prediction of a further scalar state, f ′ 0(1500 − 1800) which couples strongly to KK̄, ηη and ηη. Signatures for a possible tensor glueball at ∼2 GeV are also considered. Submitted to Phys. Rev. D E-mail : [email protected] E-mail : [email protected]

Mixing of Scalar Glueball and Scalar Quarkonia
The isosinglet scalar mesons f0(1710), f0(1500), f0(1370) and their mixing are studied. Two recent lattice results are employed as the starting point; one is the approximate SU(3) symmetry in the scalar sector above 1 GeV for the connected insertion part without qq̄ annihilation, and the other is the scalar glueball mass at 1710 MeV in the quenched approximation. In the SU(3) symmetry limit, f0(...
متن کاملScalar Glueball, Scalar Quarkonia, and their Mixing
The isosinglet scalar mesons f0(1710), f0(1500), f0(1370) and their mixing are studied. We employ two recent lattice results as the starting point; one is the isovector scalar meson a0(1450) which displays an unusual property of being nearly independent of quark mass for quark masses smaller than that of the strange, and the other is the scalar glueball mass at 1710 MeV in the quenched approxim...
متن کاملScalar Quarkonium and the Scalar Glueball
The identification of fJ(1710) as the lightest scalar glueball is supported at present by two different sets of calculations. For the valence approximation to the infinite volume continuum limit of the lightest scalar glueball mass, a calculation on GF11 [1], using 25000 to 30000 gauge configurations, gives 1740 ± 71 MeV. An independent calculation by the UKQCD-Wuppertal [2] collaboration, usin...
متن کاملHunting the Scalar Glueball: Prospects for BES III
The search for the ground state scalar glueball G0 is reviewed. Spin zero glueballs will have unique dynamical properties if the < G0|qq > amplitude is suppressed by chiral symmetry, as it is to all orders in perturbation theory: for instance, mixing of G0 with qq mesons would be suppressed, radiative Ψ decay would be a filter for new physics in the spin zero channel, and the decay G0 → KK coul...
متن کامل1 Properties of the Scalar Mesons f0(1370), f0(1500) and f0(1710)
In the three-state mixing framework, considering the possible glueball components of η and η, we investigate the hadronic decays of f0(1370), f0(1500) and f0(1710) into two pseudoscalar mesons. The quarkonia-glueball content of the three states is determined from the fit to the new data presented by the WA102 Collaboration. We find that these data are insensitive to the possible glueball compon...
