- 論文の詳細を見る
In order to improve several results on multiplicity distribution by means of formulae derived from a pure birth process, we consider a two-component model, i. e., the pure birth process with a Poisson process. We obtain better results for C_q=<n^q>/<n>^q moments in high energy collisions, provided that the number of the "excited hadrons" at the initial stage is constant irrespective of the incident energy √<s>. A KNO scaling function in the two-component model is also derived and applied to data. Moreover, the foward-backward correlation is considered. Details of caluculations are presented.
