Study of u and d quark form factors in light front wave function with N2LO approximation

In this paper, we have calculated the Dirac and Pauli form factors for u and d quark with light front quark model in N2LO approximation for MSTW2008 quark function distributions. By using this approximation we found the parameters of Dirac and Pauli form factors, and then we calculated the form factors function as \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$ Q^{2}$\end{document}. By comparing with experimental data we concluded that \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$ F_{1}(Q^{2})$\end{document} and \documentclass[12pt]{minimal} \usepackage{amsmath} \usepackage{wasysym} \usepackage{amsfonts} \usepackage{amssymb} \usepackage{amsbsy} \usepackage{mathrsfs} \usepackage{upgreek} \setlength{\oddsidemargin}{-69pt} \begin{document}$ F_{2}(Q^{2})$\end{document} are in good agreement with the experimental data.
