Abstract:
Secondary charged particles produced in hadron-hadron collisions are divided quantitatively into two kinds in the light of the picture given by the authors [1, 2] and the results deduced therefrom. One of these parts, the genuine newborn particles, is analysed by means of the N(Q) dependence in [1]. Under the assumption that the dependence of the fluctuation of the number of newborn quark pairs on the ratio of kinetic to potential energies takes the form of a compound Poisson distribution, it is shown that the multiplicity distributions, dispersions, correlations and KNO scaling in pp collisions can be fitted with a single parameter on a unified basis. General formula of moments c≡<n>k/<n>k are given and their asymptotic properties are studied, resulting in an explanation of the appearance and behavior of the KNO scaling. A brief ldiscussion is given to the possible origin of the multiplicity distribution.
