我们回顾的理论背景，实验技术，和现象学在相对论重离子物理学中被称为Glauber模型，这是用来计算几何量。一个简短的历史，原来的Glauber模型，重点是它的发展成为纯粹的经典，几何图片用于当今的数据分析。光学极限和蒙特卡罗方法之间的区别，这是经常互换使用，但在特定的情况下有一些本质的区别。四个RHIC实验所使用的方法进行了比较和对比，虽然最终的结果是令人放心的各种几何观测相似。最后，强调了几个重要的RHIC测量依赖于几何量，估计从Glauber计算，从实验观测值得出的见解。简要讨论了Glauber模型在下一代重离子物理研究中的地位和前景。
We review the theoretical background, experimental techniques, and phenomenology of what is known in relativistic heavy ion physics as the Glauber model, which is used to calculate geometric quantities. A brief history of the original Glauber model is presented, with emphasis on its development into the purely classical, geometric picture used for present-day data analyses. Distinctions are made between the optical limit and Monte Carlo approaches, which are often used interchangeably but have some essential differences in particular contexts. The methods used by the four RHIC experiments are compared and contrasted, although the end results are reassuringly similar for the various geometric observables. Finally, several important RHIC measurements are highlighted that rely on geometric quantities, estimated from Glauber calculations, to draw insight from experimental observables. The status and future of Glauber modeling in the next generation of heavy ion physics studies is briefly discussed.
