高能强子-核碰撞中KNO标度多重数分布的普适性破坏与多源模型

BREAK DOWN OF UNIVERSALITY OF KNO SCALED MULTIPLICITY DISTRIBUTIONS IN HIGH ENERGY HADRONNUCLEUS COLLISIONS AND MULTISOURCE MODEL

本文用多源模型(Multisource Model)计算了高能强子-核碰撞的多重数高次矩.计算结果与最近的N.N.Biswas等人的实验数据符合较好,自然地解释了强子-核碰撞的KNO标度普适性破坏.

Higher moments of the multiplicity distributions in high energy hadron-nucleus collisions are calculated in the framework of the Multisource Model. The results are in agreement with the data presented by N. N. Biswas et al. It naturally explains the break down of the universality of KNO scaling in high energy hadron-nucleus collisions.
