标题： Parametrization of zero-skewness unpolarized GPDs

摘要： 最近对部分子分布函数（PDFs）的参数化已经导致了在极限$\xi$$\to 0$ 下核子的引力形式因子与核子广义部分子分布函数的依赖关系的确定。 本文旨在使用 VS24 假设和在 GPDs 中的$N^3L0$近似下的两个 PDFs 来获得核子电磁和引力形式因子的味分解。 PDFs 和 GPDs 的形式主义使得能够在不同近似下计算核子的各种形式因子，以及计算核子的电半径。 尽管这项研究具有较高的近似复杂性，但它提高了计算的准确性，并使其更接近实验值。 显示英文摘要

摘要： Recent parameterizations of parton distribution functions (PDFs) have led to the determination of the gravitional form factors of the nucleon's dependence on generalized parton distributions of nucleons in the limit $\xi$$\to 0$. This paper aims to obtain the flavor division of nucleon electromagnetic and gravitional form factors using the VS24 Ansatz and two PDFs at $N^3L0$ approximation in GPDs. The PDFs and GPDs formalism enable the calculation of various form factors of nucleons in different approximations, as well as the calculation of the electric radius of nucleons. The study, despite its high approximation complexity, enhances the accuracy of calculations and brings them closer to the experimental values.
