ABSTRACT Data taken with the ALEPH detector at LEP1 have been used to search for γγ production of the glueball candidates f0(1500) and fJ(1710) via their decay to π+π−. No signal is observed and upper limits to the product of γγ width and π+π− branching ratio of the f0(1500) and the fJ(1710) have been measured to be and at 95% confidence level.

    ABSTRACT: The non-perturbative nature of Quantum Chromodynamics (QCD) at low energies has prompted the expectation that the gauge-bosons of QCD -- gluons -- might give rise to compound objects denoted as glueballs. Experimental signals for glueballs have represented a matter of research for various collaborations in the last decades; future research in this direction is a main endeavour planned by the PANDA Collaboration at FAIR. Hence in this article I review some of the outstanding issues in the glueball search, particularly with regard to the ground state -- the scalar glueball, and discuss the relevance for PANDA at FAIR.

    ABSTRACT: A combined analysis of data on the isoscalar S-wave processes ππ→ππ, KK̄, ηη and on decays J /ψ→ϕππ, ϕKK̄ from the DM2, Mark III, and BES II Collaborations is performed to study f0 mesons. The method of analysis is based on analyticity and unitarity and uses an uniformization procedure. In the analysis limited only to the multichannel ππ-scattering data, two possible sets of parameters of the f0(500) were found: In both cases the mass was about 700 MeV but the total width was either about 680 or 1040 MeV. The extension of the analysis using only the DM2 and Mark III data on the J /ψ decays does not allow us to choose between these sets. However, the data from BES II on the di-pion mass distribution in the decay J /ψ→ϕπ+π- clearly prefer the wider f0(500) state. Spectroscopic implications from the results of the analysis are also discussed.
