本文详细介绍了相对论性重离子碰撞的Hanbury Brown/Twiss粒子干涉测量方法。它们利用相同的两粒子相关性来获得最终冻结阶段的时空几何和动力学。建立了在有末态相互作用和没有末态相互作用的情况下，动量空间中测量的相关系数与粒子发射器相空间结构之间的联系。推导了适合于两粒子相关函数的高斯参数化，并解释了其参数的物理解释。在回顾了各种模型研究之后，我们展示了单粒子和双粒子光谱的组合分析如何允许重建相对论性重离子碰撞的最终状态。
In this report we give a detailed account on Hanbury Brown/Twiss (HBT) particle interferometric methods for relativistic heavy-ion collisions. These exploit identical two-particle correlations to gain access to the space-time geometry and dynamics of the final freeze-out stage. The connection between the measured correlations in momentum space and the phase-space structure of the particle emitter is established, both with and without final state interactions. Suitable Gaussian parametrizations for the two-particle correlation function are derived and the physical interpretation of their parameters is explained. After reviewing various model studies, we show how a combined analysis of single- and two-particle spectra allows to reconstruct the final state of relativistic heavy-ion collisions.
