摘要:

利用弦熔化多相输运模型(AMPT),分析了$\sqrt{S_{NN}}=19.6, 27, 39, 62.4, 200$ GeV中心Au+Au碰撞中HBT半径$R_{\rm s}$与横向动量的关系以及单π介子横向角分布.并基于一系列函数,建立了这两种现象之间的数值联系。我们可以从HBT的分析中估计出单π介子的横向角分布。

英文摘要:

With the string melting version of a multiphase transport(AMPT) model, we analyze the transverse momentum dependence of HBT radius $R_{\rm s}$ and the single-pion transverse angle distribution in central Au+Au collisions at $\sqrt{S_{NN}}=19.6, 27, 39, 62.4, 200$ GeV. And base on a series of functions, a numerical connection between these two phenomena has been built. We can estimate the single-pion transverse angle distribution from the HBT analysis.
