We compare recent MINERvA antineutrino-hydrogen charged-current measurements to phenomenological predictions of the axial-vector form factor based on fits to all available electron scattering and deuterium bubble-chamber data and to representative lattice-QCD (LQCD) determination by the PNDME Collaboration. While there is 1σ–2σ agreement in the cross section with MINERvA data for each bin in Q2, we identify three regions with different relevance and opportunity for LQCD predictions.
