INCLUSIVE RAPIDITY CORRELATIONS OF PI- MESONS IN PP INTERACTIONS

The simple single-parameter approximation of one-particle semi-inclusi ve rapidity distributions of negative particles (pi- mesons) in pp int eractions at various multiplicities over the investigated range of pri mary momenta 6.6 - 400 GeV/c is presented. Assuming the lack of any ki nd of correlations in semi-inclusive events, a good description of exp erimental data on two-particle inclusive rapidity correlations (pseudo correlations) is obtained. Data on forward-backward, right-left correl ations and multiplicity distributions in rapidity intervals and interv als separated by empty gaps do not contradict independent pi- producti on either.
