Examining the structure functions of nucleons by introducing new ansatz and their consequences on parton distribution functions in higher approximation

By introducing ansatz and using a PDF at the \(N^3LO\) approximation in this paper, we have studied the structure of the nucleons in generalized parton distributions. For this purpose, the form factors and the electric radius of nucleons, as well as the quark’s form factors, are calculated in this paper. These calculations give important new information about the nucleons and the distribution of partons within them. The results are analyzed, and to validate them, the abstract emphasizes the importance of comparing the results with existing research and experimental data. By varying the free appropriate parameters of the new ansatz, the study seeks to optimize the model, ensure its suitability for accurately describing the nucleon’s internal structure, and provide valuable insights about the distribution of partons.
