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.
