关于STAR数据的多重相关

On multiplicity correlations in the STAR data

K. Fialkowski, R. Wit

摘要:

本文讨论了pp和AuAu碰撞中窄赝快度仓多重数关联的STAR数据。PYTHIA 8.145生成器用于pp数据,并且提出了用于AuAu数据的朴素叠加模型。结果表明,PYTHIA发电机与默认参数值描述的PP数据相当不错,而叠加模型未能再现的中心依赖的数据。一些可能的原因,这种失败,并与其他模型的比较。

英文摘要:

The STAR data on the multiplicity correlations between narrow psudorapidity bins in the pp and AuAu collisions are discussed. The PYTHIA 8.145 generator is used for the pp data, and a naive superposition model is presented for the AuAu data. It is shown that the PYTHIA generator with default parameter values describes the pp data reasonably well, whereas the superposition model fails to reproduce the centrality dependence seen in the data. Some possible reasons for this failure and a comparison with other models are presented.
