Measurements of the inclusive cross-sections for K 0 and Λ production in hadronic decays of the Z are presented together with measurements of two-particle correlations within pairs of Λ and K 0. The results are compared with predictions from the hadronization models Jetset, based on string fragmentation, and Herwig, based on cluster decays. The K 0 spectrum is found to be harder than predicted by both models, while the Λ spectrum is softer than predicted. The correlation measurements are all reproduced well by Jetset, while Herwig misses some of the qualitative features and overestimates the size of theΛ bar Λ correlation.

Abstract

Measurements of the inclusive cross-sections for K 0 and Λ production in hadronic decays of the Z are presented together with measurements of two-particle correlations within pairs of Λ and K 0. The results are compared with predictions from the hadronization models Jetset, based on string fragmentation, and Herwig, based on cluster decays. The K 0 spectrum is found to be harder than predicted by both models, while the Λ spectrum is softer than predicted. The correlation measurements are all reproduced well by Jetset, while Herwig misses some of the qualitative features and overestimates the size of theΛ bar Λ correlation. Finally, the possibility of Bose-Einstein correlation in the K {/S 0} K {/S 0} system is discussed.
