Abstract

The theoretical and experimental status of the isovector axial-vector current form factors G_A(q²) and G_P(q²) of the nucleon is reviewed. We also describe a new calculation of these form factors in manifestly Lorentz-invariant chiral perturbation theory (ChPT) with the inclusion of axial-vector mesons as explicit degrees of freedom.
