摘要

本文对 MD-BFKL 方程进行了全面分析，同时考虑了胶子重组过程中的阴影效应和反阴影效应。通过对 MD-BFKL 方程的求解，我们得出了未整合胶子分布的分析表达式，其中包含和不包含反阴影效应，从而为这些效应对未整合胶子分布行为的影响提供了新的见解。与 CT18NLO 胶子分布函数的结果相比，我们的结果表明反阴影效应对未积分胶子分布特性的影响明显更强，尤其是在高快速和高动量区域。这项工作极大地促进了对胶子重组机制及其在高能物理中影响的理解。

Exploring the impact of anti-shadowing effect on unintegrated gluon distributions in the MD-BFKL equation*

This paper presents a comprehensive analysis of the MD-BFKL equation, considering both shadowing and anti-shadowing effects in gluon recombination processes. By deriving analytical expressions for unintegrated gluon distributions through the solution of the MD-BFKL equation, with and without the incorporation of the anti-shadowing effect, we offer new insights into the influence of these effects on the behavior of unintegrated gluon distributions. Our results, when compared to those from the CT18NLO gluon distribution function, demonstrate that the anti-shadowing effect has a notably stronger impact on the characteristics of unintegrated gluon distributions, particularly in regions of high rapidity and momentum. This work significantly contributes to the understanding of gluon recombination mechanisms and their implications in high energy physics.
