Baryon Production in Quark Fragmentation

Hadronic decays of the Z0 provide an excellent field for the study of baryon production. I did this research with the OPAL detector at LEP.
The study of baryon-antibaryon correlations reveals local baryon number compensation in quark fragmentation.  The measured correlation strength puts stringent constraints on fragmentation models like JETSET and HERWIG.
The measurement of spin correlations between Lambda-baryons makes the study of Fermi-Dirac statistic effects possible. The published result, Phys.Lett.B384, 377 (1996), has been cited in 20 publications or more.

Hadronic Z0 decay into a Lambda anti-Lambda
pair. The event was recorded with the OPAL 
detector at LEP. Both Lambdas decay inside the 
central chamber into a proton-pion pair.
