Abstract

It is shown that experimental data on the multiparticle production of negatively charged pions in proton-proton interactions at $$\sqrt s \leqslant 30 GeV$$ do not involve significant indications of the existence of anycorrela tions between negatively charged pions, apart from those that are associated with momentum conservation and with interference. The multiplicity distributions in rapidity intervals, forward-backward correlations, and two-particle rapidity and transverse-momentum correlations do not contradict the independent production of negatively charged pions. No constraints on the multiplicity distributions of product particles follow from their independent production.
