Rapidity-rank structure of $p\overline{p}$ pairs in hadronic $Z^0$ decays

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