论文摘要
我们研究了$ \ sqrt {s} = 5.02〜 \ rm TEV $的初始状态动量相关性和事件的几何形状，通过使用JIMWLK Rapidity Evolution的方法将IP-glasma模型扩展到3D，以此。在检查可观察物的非平凡速度依赖性时，我们发现几何形状在较大的速度间隔内相关，而初始状态动量相关性的速度相对较短。根据我们的结果，我们讨论了两种影响在解释小型系统中集体现象的起源中的相关性的影响。
We study initial state momentum correlations and event-by-event geometry in p+Pb collisions at $\sqrt{s}=5.02~\rm TeV$ by following the approach of extending the IP-Glasma model to 3D using JIMWLK rapidity evolution. On examining the non-trivial rapidity dependence of the observables, we find that the geometry is correlated over large rapidity intervals, while the initial state momentum correlations have a relatively short range in rapidity. Based on our results, we discuss implications for the relevance of both effects in explaining the origin of collective phenomena in small systems.
