Violation of KNO scaling

Assuming Feynman scaling of secondary hadron spectra Koba, Nielsen and Oles en have derived energy invariance of relative multiplicity distribution. We have derived a violated KNO scaling when statistical invariance of hadro n momentum spectra is assumed. It is in reasonable agreement with collider data at high energies. The observed behaviour of multiplicity distributions could confirm the hypothesis for a smooth transition from color confined p hase to asymptotically free hadronization matter.
