论文摘要
在颜色玻璃冷凝物（CGC）有效场理论中，考虑到违反速度分布的增强不变性的行为，我们纠正了纵向速度岭相关性的归一化方案。校正后，底部后的大宽脊相关反弹，与CMS检测器的观察到的数据一致。还发现，相关反弹出现在弹丸和靶标的饱和动量之和，并在较高的碰撞能量下移至较大的速度。这些特征直接是由CGC框架内的饱和度和量子演变而产生的。
Within the Color Glass Condensate (CGC) effective field theory, considering the violation of boost invariance of the rapidity distribution, we correct the normalization scheme of the longitudinal rapidity ridge correlations. After this correction, the large-rapidity ridge correlation rebounds after bottoming, consistent with the observed data from the CMS detector. It is also found that the correlation rebound appears around the sum of the saturation momentum of the projectile and target, and moves to larger rapidities at higher collision energies. These features directly result from the saturation and the quantum evolution of gluons within the framework of the CGC.
