TL;DR: A new measurement of the parity-violating asymmetry in quasielastic electron scattering from the deuteron at backward angles at Q2=0.038 (GeV/c)2 is reported, which provides a determination of the neutral weak axial vector form factor of the nucleon, which can potentially receive large electroweak corrections.
