Δ++ production in hadronic Z 0 decays
Abstract
The production of Δ++ baryons has been measured using 3.5 million hadronic Z 0 decays collected with the OPAL detector at LEP. The production rate and fragmentation function are presented. A total of 0.22 ± 0.04 ± 0.04 Δ ++ + ( overlineΔ) - per hadronic Z 0 decay is observed. The fragmentation function is found to be softer than that predicted by the JETSET and HERWIG Monte Carlo event generators. With this measurement of Δ++ production, at least one baryon of each strangeness level in the lightest baryon decuplet has now been measured at LEP.
