AbstractAbstract
[en] Preliminary results on the production and decay of the f0(975) meson in the processes J/Ψ → φπ+π-, J/Ψ → φπ0π0, J/Ψ → φK+K-, and J/Ψ → ωπ+π- are reported on. The data sample, corresponding to 5.8 x 106 produced J/Ψ's, were collected with the MARK-III detector at SPEAR. In a coupled- channel fit to the invariant mass distribution of the π+π- system opposite the φ, the f0(975) product branching ratios, resonance parameters and couplings to K+K- and π+π- are extracted. An upper limit on f0(975) production in conjunction with an ω is presented. 15 refs., 4 figs., 4 tabs
