论文摘要
我们提出了DGLAP改善饱和模型相对于非线性校正（NLC）的修改。通过使用Laplace Transforms方法，使用质子结构函数的参数化来考虑GLR-MQ改进的饱和模型，该方法将其行为成功保存在低和高$ q^{2} $区域中。我们表明，在宽运动区域$ rq_ {s} $中，GLR-MQ改进模型的几何缩放率具有。这些结果与宽的运动区域$ rq_ {s} $中的其他模型相媲美。相对于GLR-MQ改善的饱和模型，偶极子横截面的行为与彩色玻璃冷凝物（CGC）模型相当。该模型描述了包含和衍射过程中的偶极子横截面。我们还将非线性校正与影响参数依赖性饱和度（IP-SAT）模型与依赖性参数依赖的颜色玻璃冷凝物（B-CGC）偶极子模型进行了比较。最后，我们将线性和非线性校正视为IP非SAT模型。这些结果为未来的实验（例如大型强子对撞机和未来的圆形对撞机项目）的小$ x $进一步研究QCD提供了基准。
We present a modification of the DGLAP improved saturation model with respect to the nonlinear correction (NLC). The GLR-MQ improved saturation model is considered by employing the parametrization of proton structure function due to the Laplace transforms method, which preserves its behavior success in the low and high $Q^{2}$ regions. We show that the geometric scaling holds for the GLR-MQ improved model in a wide kinematic region $rQ_{s}$. These results are comparable with other models in a wide kinematic region $rQ_{s}$. The behavior of the dipole cross sections, with respect to the GLR-MQ improved saturation model, are comparable with the Color Glass Condensate (CGC) model. The model describes the dipole cross sections in the inclusive and diffractive processes. We also compare the nonlinear corrections to the impact-parameter dependent saturation (IP-Sat) model with the impact-parameter dependent color glass condensate (b-CGC) dipole model. Finally, we consider the linear and nonlinear corrections to the IP Non-Sat model. These results provide a benchmark for further investigation of QCD at small $x$ in future experiments such as the Large Hadron Collider and Future Circular Collider projects.
