摘要

在初始尺度 \(Q_{0}^2\)上研究了非线性修正对动量和规则的重要性。研究发现，在未来对撞机的低x对核子和轻核的高阶近似中，非线性修正在单子和胶子动量和则中扮演着不可或缺的角色。通过这种方法，我们得到了在热点处的单子和胶子动量和规则在低x处的显著不同行为。

Nonlinear corrections to the momentum sum rule

The importance of nonlinear corrections to the momentum sum rule is investigated on the initial scale \(Q_{0}^2\). Nonlinear corrections are found to play an indispensable role in the singlet and gluon momentum sum rule in the high-order approximations in the parton distribution function parameterizations for nucleons and light nuclei at low x in future colliders. In this way, we obtain a significantly different low x behavior of the singlet and gluon momentum sum rule at the hotspot point.
