高能核-核碰撞的灰粒子多重数分布和统计模型

Multiplicity Distribution of Grey Particles in High Energy Nucleus-Nucleus Collisions and Statistical Model

本文用统计模型讨论了高能核-核碰撞中灰粒子的产生过程,给出与实验数据相符合的灰粒子多重数分布,并分析了靶核参加者数目N,碰撞参数b与灰粒子多重数n_g的关联。

The production process of grey particles in high energy, nucleus-nucleus collisions is investigated in this paper. The comparison of the experimental mulitiplicity distributions with the calculations reveals that the statistical model well describes the production of grey particles. The correlation between the number of participating target N, the impact parameter b and the multiplicity of grey particles n_g is studied.
