Abstract: (Elsevier)

The rapidity-rank structure of p p ̄ pairs is used to analyze the mechanism of baryon production in hadronic Z 0 decay. The relative occurrence of the rapidity-ordered configuration p M p ̄ , where M is a meson, and that of p p ̄ adjacent pairs is compared. The data are found to be consistent with predictions from a mechanism producing adjacent-rank p p ̄ pairs, without requiring `string-ordered' p M p ̄ configurations. An upper limit of 15% at 90% confidence is determined for the p M p ̄ contribution.
