The scalar mesons in decays of the ψ and Υ{hooked} families

Abstract

The f₀ mesons are studied in a combined analysis of data on isoscalar S-wave processes ππ→ππ,KK,ηη and on decays J/ψ→φ(ππ,KK), ψ(2S)→J/ψ(ππ) and Υ{hooked}(2S)→Υ{hooked}(1S)ππ from the Argus, Crystal Ball, CLEO, CUSB, DM2, Mark II, Mark III, and BES III Collaborations. The method of analysis is based on analyticity and unitarity and uses an uniformization procedure. Some spectroscopic implications from results of the analysis are discussed.
