论文摘要
我们模拟了纵向扩展核的碰撞的3+1 d经典的阳米尔斯动力学，这是由颜色玻璃冷凝物框架中的Eikonal颜色电荷描述的。通过改变碰撞核的纵向厚度，我们讨论了对增强不变性的违规行为，并探讨了如何接近增强不变的高能量极限。随后，我们开发了三维颜色电荷分布的更现实的模型，该模型将纵向和横向波动连接到$ x $和$ k_ \ bot $横向动量依赖性parton分布的依赖性，并探索产生的快速曲线及其纵向波动。
We simulate the 3+1 D classical Yang-Mills dynamics of the collisions of longitudinally extended nuclei, described by eikonal color charges in the Color Glass Condensate framework. By varying the longitudinal thickness of the colliding nuclei, we discuss the violations of boost invariance and explore how the boost invariant high-energy limit is approached. Subsequently, we develop a more realistic model of the three dimensional color charge distributions that connects longitudinal and transverse fluctuations to the $x$ and $k_\bot$ dependence of transverse momentum dependent parton distributions, and explore the resulting rapidity profiles and their longitudinal fluctuations.
