Parameterization of zero-skewness unpolarized GPDs

Abstract Recent parameterizations of parton distribution functions (PDFs) have led to the determination of the gravitational form factors pertaining to the dependence of nucleons on their generalized parton distributions (GPDs) in the limit . This study aims to obtain the flavor division of nucleon electromagnetic and gravitational form factors using the VS24 ansatz and two PDFs at the approximation in GPDs. The PDFs and GPD 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 aligns them more closely with experimental values.
