Scalar 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...

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(...

Scalar 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...

Scalar Charmonium and Glueball Mixing in E

We study the possibility of the scalar charmonium and glueball mixing in e + e − annihilation at √ s = 10.6 GeV. The effects can be used to explain the unexpected large cross section (12 ± 4 fb) and the anomalous angular distribution (α = −1.1 +0.8 −0.6) of the exclusive e + e − → J/ψχ c0 process observed by Belle experiments at KEKB. We calculate the helicity amplitudes for the process e + e −...

Scalar mesons: in search of the lightest glueball

According to the QCD expectations the lightest glueball should be a scalar particle (J = 0). Different scenarios have been considered for a classification of these states but – despite considerable progress in recent years – the experimental basis for various parameters is still rather weak. We present a new analysis of the elastic and charge exchange ππ scattering between 1000 and 1800 MeV. A ...
