Measurements of the inclusive cross-sections for K0 and LAMBDA production in hadronic decays of the Z are presented together with measurements of two-particle correlations within pairs of LAMBDA and K0. The results are compared with predictions from the hadronization models Jetset, based on string fragmentation, and Herwig, based on cluster decays. The K0 spectrum is found to be harder than predicted by both models, while the LAMBDA 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 the LAMBDA (LAMBDA) over bar correlation. Finally, the possibility of Bose-Einstein correlation in the K(S)0K(S)0 system is discussed.

Abstract

Measurements of the inclusive cross-sections for K0 and LAMBDA production in hadronic decays of the Z are presented together with measurements of two-particle correlations within pairs of LAMBDA and K0. The results are compared with predictions from the hadronization models Jetset, based on string fragmentation, and Herwig, based on cluster decays. The K0 spectrum is found to be harder than predicted by both models, while the LAMBDA 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 the LAMBDA (LAMBDA) over bar correlation. Finally, the possibility of Bose-Einstein correlation in the K(S)0K(S)0 system is discussed.
