Abstract

It is shown that parton branhing equations for the probability Pmn of m quarks and n gluons have exact solutions which violate KNO scaling. Only the approximate solution is exactly a KNO function. Corrections to this approximate solution approach KNO scaling from below in the high-z tail, in agreement with recent collider data and in contrast to the negative binomial distribution.
