碎裂区中核物质与辐射的分布

摘要

我们通过考虑一个静止原子核被相对论性彩色玻璃薄片撞击,来研究重离子碰撞的碎裂(远前向/后向)区。借助一个简单的经典模型,我们计算了重子及其伴随辐射的后续演化。我们确认被击原子核经历压缩,并且碰撞早期动力学最好由两种独立流体描述,因为所产生的辐射的速度分布与被击原子核中物质的速度分布差异很大。

备注

23 pages, 11 figures. We've added a pedagogical appendix to explain the relation between different frames in a heavy ion collision. A footnote has been added to the introduction. Figures 7 and 9 have been rescaled to reflect the known nominal nuclear density. We have added a sentence below Eq.3.30 to explain the implications of our results for baryon stopping power
