Determination of the generalized parton distributions through the analysis of the world electron scattering data considering two-photon exchange corrections

We determine the valence generalized parton distributions (GPDs) $ H_v^q and E_v^q with their uncertainties at zero skewness by performing a \chi^2 analysis of world electron scattering data considering two-photon exchange corrections. The include wide updated range electric magnetic form factors (FFs) proton neutron. As result, we find that there are no enough constraints on GPDs from FFs solely though well constrained. By including new charge radius nucleon in analysis, show they put final GPDs, especially $. Moreover, calculate gravitational FF M_2 total angular momentum J^q using extracted compare them obtained light-cone QCD sum rules (LCSR) Lattice QCD. our results interestingly good consistency pure theoretical predictions.
