Generalized parton distributions at zero skewness

We present a new determination of the generalized parton distributions (GPDs) with their uncertainties at zero skewness, $ \xi =0 $, through simultaneous analysis all available experimental data nucleon electromagnetic form factors (FFs), charge and magnetic radii, proton axial FFs (AFFs) wide-angle Compton scattering (WACS) cross sections for first time, we investigate whether there is any tension between these data. This can be considered most comprehensive GPDs \xi=0 performed so far. show that such an provides three kinds GPDs, namely H^q \widetilde{H}^q E^q considering also sea-quark contributions. As result, find inclusion WACS AFF larger values momentum transfer squared Q^2=-t put constraints on change them drastically in some cases. considerable factor ($ G_M^p $) data, especially -t $. However, indicate results gravitational FF M_2 total angular J^p calculated using extracted are relatively good agreement light-cone QCD sum rules (LCSRs) lattice predictions when contributions both included analyses simultaneously.
