RHIC能区的纵向流分布特征和核阻止特性的研究

首先利用相对论纵向非均匀集体流模型讨论RHIC能区的净质子分布特征,并分别与AGS,SPS的实验结果比较,发现,RHIC能区所产生的粒子系统具有很强的非均匀分布特征,表现为很强的核透明性,并分析了非均匀集体流模型与实验中的核阻止特性的紧密联系,接着分别研究了RHIC能区所产生质子、反质子和净质子的分布,这些研究可以帮助我们深入了解最新的RHIC能区的粒子分布和核阻止特征.

Study on the Feature of Longitudinal Collective Flow Distribution and Nuclear Stopping at RHIC

The net-proton distribution features at RHIC have been analyzed by using non-uniform flow model in this paper. It is found that the system produced at the RHIC energy region has stronger non-uniform feature than at the AGS and SPS energy regions, which means that nuclei at RHIC energy region is much more transparent. It is shown that our analysis relates closely to the study of nuclear stopping of experiment. And then, the proton,anti-proton and net-proton distributions are studied , respectively. This investigation help us to understand the feature of particle stopping in the newest RHIC experiment.
