Descripción: 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 Σ+ 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: $N_{Σ^{+}} + N_{Σ̄^{+}} =0.114±0.011_{stat} ±0.009_{syst}$ $N_{Σ^{0}} + N_{Σ̄^{0}} =0.095±0.015_{stat} ±0.013_{syst} .$ These rates are found to be higher than the predictions from Monte Carlo hadronization models and analytical parameterizations of strange baryon production.
