论文摘要
在本文中，我们研究了QCD动力学的非线性方法对较高的扭曲效应的影响，对将在未来的电子山脉中测量的包容性可观察物进行了重新介绍。我们假设偶极子 - 核散射幅度的现象学模型，它考虑了非线性校正，并估算了以$ f_2^a（x，q^2）$，$ f_l^a（x，x，q^2）$和$ \ partial f _2^a /\ pottial ln q^p photor -fivile thive bemoive的$ f_2^a（x，q^2）$，$ f_l^a（x，q^2）$ forive a b formation -bj aft of thive bemoive的贡献。 $ q^2 $和原子数$ a $。进行了与完整预测的比较，并估计了不同曲折的影响。我们的结果表明，对数$ q^2 $斜率和纵向结构功能的未来分析将使我们能够探究非线性效应对QCD动力学的存在。
In this paper we investigate the impact of the higher - twist effects, resummed by the non - linear approaches for the QCD dynamics, on the inclusive observables that will be measured in future electron - ion colliders. We assume a phenomenological model for the dipole - nucleus scattering amplitude which takes into account the non - linear corrections and estimate the contribution of the different twists for $F_2^A(x,Q^2)$, $F_L^A(x,Q^2)$ and $\partial F_2^A /\partial ln Q^2$ considering different values of the Bjorken - $x$ variable, photon virtuality $Q^2$ and atomic number $A$. A comparison with the full predictions is performed and the impact of the distinct twists is estimated. Our results indicate that a future analysis of the logarithmic $Q^2$ slope and longitudinal structure function will allow us to probe the presence of the non - linear effects on the QCD dynamics.
