Abstract
A recently proposed model for the longitudinal- and transverse-momentum distribution of quantum-chromodynamics (QCD) radiation is shown to lead naturally to mean scaling. Excellent agreement is found for the normalized momentum distribution in between our predictions and the data from 13 to 1500 GeV/c with , the number of pions, varying from 4 to 26. We also show that -pair production by hadrons exhibits the same transverse-momentum spectrum as do the hadrons produced in annihilation. This transverse scaling in the mean in terms of the dimensionless variable is interpreted as reflecting the primary (soft-gluon) QCD radiation distribution. Again, very good agreement is found for these normalized distributions and our theoretical scaling curves.
