New insight on the nucleon structure from recent MINERvA measurement of the antineutrino-proton scattering cross-section

We investigate the impact of the new measurement of the antineutrino-proton scattering cross-section from the MINERvA Collaboration on the generalized parton distributions (GPDs), especially of polarized GPDs $ \widetilde{H}^q $. To this aim, we perform some QCD analyses of the MINERvA data in addition to all available data of the proton axial form factors (FFs) $ F_A $. We show that the MINERvA data are in a good consistency with the other related experimental data which confirms the universality of GPDs in turn. Our results indicate that the MINERvA data can put new constrains on GPDs, especially $ \widetilde{H}^q $. The present study can be considered as a guideline for performing a new and comprehensive QCD global analysis of GPDs including the MINERvA measurements like as Phys. Rev. D \textbf{107}, 096005 (2023).
