Abstract

We report on measurements of the inclusive production rate of Σ⁺ and Σ⁰ baryons in hadronic Z decays collected with the L3 detector at LEP. The Σ⁰ baryons are detected through the decay Σ⁺ → pπ⁰, while the Σ⁰ baryons are detected via the decay mode Σ⁰ → Λγ. The average numbers of Σ⁺ and Σ⁰ per hadronic Z decay are measured to be: <N(Σ⁺)> + <N(Σ⁺)> = 0.114 ± 0.011(stat) ± 0.009(syst) <N(Σ⁰)> ± <N(Σ⁰)> = 0.095 ± 0.015(stat) ± 0.013(syst). These rates are found to be higher than the predictions from Monte Carlo hadronization models and analytical parameterizations of strange baryon production. (C) 2000 Elsevier Science B.V.
