Nucleon axial-vector radius and form factor from lattice QCD, MINERvA antineutrino-proton data, and future neutrino experiments

ORAL

Abstract

We compare a new MINERvA measurement of the nucleon axial-vector form factor with lattice-QCD calculations and deuterium bubble-chamber data, provide uncertainty projections for future extractions, and present recent calculations of radiative corrections to charged-current (anti)neutrino-nucleon scattering.
