RHIC多重数分布和叠加模型

RHIC multiplicity distributions and superposition models

K. Fialkowski, R. Wit

摘要:

在叠加模型的框架下,分析了最近PHENIX中快度测量的中心性仓多重数分布。PP事件的一个简单的叠加示出不同意作为中心性的函数的分散的重离子数据。然而,我们认为,一个适当地描述pp数据并基于“受伤夸克”思想的模型可能与重离子碰撞的多重数数据相容。

英文摘要:

The recent PHENIX mid-rapidity measurements of multiplicity distributions for centrality bins are analyzed in the framework of superposition models. A simple superposition of pp events is shown to disagree with the heavy ion data for dispersion as a function of centrality. However, it is suggested that a model describing properly the pp data and based in the "wounded quark" idea may be compatible with the multiplicity data for heavy ion collisions.
