论文摘要
我们重新探讨了核核碰撞中弹丸的第一个饱和校正\ cite {chirilli：2015tea}在示意光锥扰动理论（LCPT）中。为了获得\ cite {chirilli：2015tea}弹丸作者饱和校正的分析表达式，计算完整的$ {\ cal {o}}}（g^3）$振幅，其中主要结果给出了横向坐标空间。但是，要在弹丸中找到完整的第一个饱和校正，需要计算$ {\ cal {o}}（g^3）$和$ {\ cal {o}}（g^5）$ gluon生产振幅。我们在这里介绍了$ {\ cal {o}}（g^5）$在图表光锥扰动理论中的详细计算。
We revisited the first saturation correction to projectile in nucleus-nucleus collisions \cite{Chirilli:2015tea} within diagrammatic light cone perturbation theory (LCPT). To get an analytic expression for the saturation correction in projectile authors in \cite{Chirilli:2015tea} calculated complete ${\cal{O}}(g^3)$ amplitudes, where the main results are given in transverse coordinate space. However to find the complete first saturation correction in the projectile, one needs to calculate both ${\cal{O}}(g^3)$ and ${\cal{O}}(g^5)$ gluon production amplitudes. We here present a detailed calculation of a sample graph at ${\cal{O}}(g^5)$ in diagrammatic light cone perturbation theory.
