Abstract

To study the nature of the quark-hadron phase transition, it is important to investigate the space-time structure of the hadron-emitting source in heavy-ion collisions. Measurements of HBT correlations have proven to be a powerful tool to gain information about the source. In these proceedings, we report the current status of the analysis of source parameters obtained from Lévy fits to the measured one-dimensional two-pion correlation functions in Au + Au collisions at \(\sqrt {{{s}_{{NN}}}} \) = 200 GeV.

STAR的HBT相关性的形状分析

摘要

研究夸克-强子相变的性质，研究重离子碰撞中强子发射源的时空结构很重要。事实证明，对HBT相关性的测量是获得有关源信息的强大工具。在这些程序中，我们报告了从Lévy拟合获得的源参数分析的当前状态，其与\（\ sqrt {{{s} _ {{NN} }}} \） = 200 GeV。
