Inclusive Σ+ and Σ0 production in hadronic Z decays
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 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:NΣ++NΣ̄+=0.114±0.011stat±0.009systNΣ0+NΣ̄0=0.095±0.015stat±0.013syst.These rates are found to be higher than the …
