标题： Unequal rapidity correlators in the dilute limit of JIMWLK

摘要： 我们研究在颜色玻璃凝聚有效场理论中的Jalilian-Marian - Iancu - McLerran - Weigert - Leonidov - Kovner (JIMWLK)演化中，随机朗之万图景中的不等快速度关联。 通过分别演化直接幅度和复共轭幅度中的威尔逊线，我们使用该形式来研究大快速度分离下的两粒子产生。 我们证明，两个产生粒子的快速度之间的演化可以表示为一个线性方程，即使在完全非线性极限下也是如此。 我们还展示了两粒子关联的朗之万形式在稀疏极限和动量空间中如何退化为BFKL图景，从而对BFKL演化提供了一种作为颜色电荷随机过程的解释。 显示英文摘要

摘要： We study unequal rapidity correlators in the stochastic Langevin picture of Jalilian-Marian - Iancu - McLerran - Weigert - Leonidov - Kovner (JIMWLK) evolution in the Color Glass Condensate effective field theory. By separately evolving the Wilson lines in the direct and complex conjugate amplitudes, we use the formalism to study two-particle production at large rapidity separations. We show that the evolution between the rapidities of the two produced particles can be expressed as a linear equation, even in the full nonlinear limit. We also show how the Langevin formalism for two-particle correlations reduces to a BFKL picture in the dilute limit and in momentum space, providing an interpretation of BFKL evolution as a stochastic process for color charges.
