Description

The production of heavy flavoured baryons, Λc+ and Λb0, has been studied in pp interactions at the ISR. Both baryons are observed in the forward region, for xF≥0.35. The results confirm the heavy baryon production to be governed by the 'leading hadron' effect. The cross-section for (anti DΛc+) associated production has been estimated with various hypotheses concerning the possible charm production mechanisms. A preliminary cross-section value is also given for (anti BΛb0) production. (orig.)
