Abstract

The rapidity-rank structure of pa 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 pp adjacent pairs is compared. The data are found to be consistent with predictions from a mechanism producing adjacent-rank pp 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. (C) 2000 Elsevier Science B.V. All rights reserved.
