我们报告了基于 2A 和 8A GeV 之间束流能量的高多重 Au+Au 碰撞中的二介子相关性的粒子源成像分析。我们应用 Brown 和 Danielewicz 引入的成像技术，该技术允许独立于模型提取源函数，并且具有有用的精度，相对介子分离约为 20 fm。提取的源函数具有高斯形状。在所研究的能量范围内，零分离时的源函数值几乎恒定。发现成像结果与多维 Hanburg-Brown-Twiss 分析获得的传统源参数一致。
We report a particle source imaging analysis based on two-pion correlations in high multiplicity Au+Au collisions at beam energies between 2A and 8A GeV. We apply the imaging technique introduced by Brown and Danielewicz, which allows a model-independent extraction of source functions with useful accuracy out to relative pion separations of about 20 fm. The extracted source functions have Gaussian shapes. Values of source functions at zero separation are almost constant across the energy range under study. Imaging results are found to be consistent with conventional source parameters obtained from a multidimensional Hanburg-Brown-Twiss analysis.
