Abstract

Cross sections are presented for the inclusive production of A hyperons in electron-positron annihilations at square-root s=29 GeV based on the full 291-pb-1 sample of data taken in the High Resolution Spectrometer experiment at the SLAC e+e- storage ring PEP. These results, and the associated correlation analyses, are consistent with the Lund model predictions with the strange diquark suppression ratio-delta fixed at 0.59+/-0.10+/-0.18, as compared to the standard Lund value of 0.32. The LAMBDA multiplicity has been found to be 0. 182+/-0.020 per event. The opposite-strangeness multiplicity [n(LAMBDA-LAMBDABAR)] has been measured to be 0.046+/-0.020, whereas the like-strangeness multiplicity [n(LAMBDA-LAMBDA+LAMBDABAR-LAMBDABAR)] is 0.009+/-0.028. A strong correlation is found between LAMBDA's and LAMBDABAR's; when one is found in an event, the other is found in the same event with a probability that exceeds 50%.
