摘要: 基于一个改进的微观动力学输运模型——极端相对论量子分子动力学（UrQMD），较为系统地研究了从SIS能区到AGS和SPS能区，再到RHIC能区，入射能量跨5个数量级的重离子核反应及多个人们感兴趣的实验观测量，如粒子产额、集体流、核阻止以及两粒子HBT关联等。研究表明，不论单粒子观测量，还是两粒子关联观测量，都能自洽地由同一个输运模型加以描述。Based on one updated microscopic transport model Ultrarelativistic Quantum Molecular Dynamics (UrQMD) with modifications of both potentials and twobody scattering cross sections, quite a few interesting observables, such as yields, collective flows, the nuclear stopping, and the HBT twoparticle interferometry, are systematically investigated for heavy ion collisions within a large beam energy regime of five orders of magnitude (from SIS, AGS, SPS up to RHIC). It is shown that a consistent explanation can be received from both singleparticle and twoparticle related observables.
