Abstract

Inclusive production of the f₀(980), f₂(1270) and φ(1020) resonances has been studied in a sample of 4.3 million hadronic Z⁰ decays from the OPAL experiment at LEP. A coupled channel analysis has been used for the f₀ in simultaneous fits to the resonances in inclusive π⁺π^- and K⁺K^- mass spectra. Fragmentation functions are reported for the three states. Total inclusive rates are measured to be 0.141 ± 0.007 ± 0.011 f₀, 0.155 ± 0.011 ± 0.018 f₂ and 0.091 ± 0.002 ± 0.003 φ mesons per hadronic Z⁰ decay. The production properties of the f₀, including those in three-jet events, are compared with those of the f₂ and φ, and with the Lund string model of hadron production. All measurements are consistent with the hypothesis that the f₀(980) is a conventional qq̄ scalar meson.
