Koba-Nielsen-Olesen scaling

A correct version of Koba-Nielsen-Olesen (KNO) scaling is described in detail for multiplicity distributions. Some statements on the violation of KNO scaling that are based on an erroneous interpretation of experimental data are discussed. An accurate comparison with data is presented for the distributions of negatively charged particles originating from electron-positron annihilation at roots = 3-161 GeV, from inelastic proton-proton collisions at roots = 2.4-62 GeV, and from nucleus-nucleus collisions at p(lab) = 4.5-520 GeV/c per projectile nucleon. Data on proton-antiproton interactions at roots = 546 GeV are also considered. (C) 2001 MAIK "Nauka/Interperiodica".
