论文摘要
当在扰动QCD中计算到近层次的顺序时，用于偶极 - - 二极管散射的高能演化的非线性Balitsky-Kovchegov（BK）方程似乎是不稳定的。我们表明，可以将这种不稳定的速度（而不是稀释偶极弹丸）作为进化时间来避免。使用此变量，我们构建了BK方程的共线版本，其中对内核的主要辐射校正（通过双胶线对数增强的辐射校正）被重新亮相到所有订单。
When computed to next-to-leading order in perturbative QCD, the non-linear Balitsky-Kovchegov (BK) equation for the high-energy evolution of the dipole-hadron scattering appears to be unstable. We show that this instability can be avoided by using the rapidity of the dense hadronic target (instead of that of the dilute dipole projectile) as the evolution time. Using this variable, we construct a collinearly-improved version of the BK equation, where the dominant radiative corrections to the kernel -- those enhanced by double collinear logarithms -- are resummed to all orders.
