论文摘要
Chou-yang类型的多样性分布包括总多数级组件和二项式不对称组件来描述$ \ sqrt {s} = $ 0.9、7和8 TEV的带电的强子多重性数据，来自CERN的CMS实验。从CERN开放数据门户获得数据并处理。对于总的多样性组件，发现负二项式分布和毛茸茸的分布的凸之和能够很好地描述KNO缩放尺度违规的肩部样结构特征。还发现碰撞产生的平均簇大小随碰撞能量增加。 $ \ sqrt {s} = $ 14 tev给出了$ pp $碰撞的预测。
A Chou-Yang type multiplicity distribution comprising a total multiplicity component and a binomial asymmetry component is used to describe charged hadron multiplicity data at $\sqrt{s}=$ 0.9, 7 and 8 TeV from the CMS experiment at CERN. The data was obtained and processed from the CERN Open Data Portal. For the total multiplicity component, it was found that a convex sum of a Negative Binomial Distribution and a Furry-Yule Distribution is able to describe the shoulder-like structure characteristic of KNO scaling violation well. The mean cluster size produced from collisions was also found to increase with collision energy. A prediction is given for $pp$ collisions at $\sqrt{s}=$ 14 TeV.
