dc.descriptionWe construct a model for the weak pion production off the nucleon, which in addition to the weak excitation of the $Δ(1232)$ resonance and its subsequent decay into $Nπ$, it includes also some background terms required by chiral symmetry. We re-fit the $C_5^A(q^2)$ form factor to the flux averaged $ν_μp \to μ^-pπ^+$ ANL $q^2-$differential cross section data, finding a substantially smaller contribution of the $Δ$ pole mechanism than traditionally assumed in the literature. We also show that the interference between the Delta pole and the background terms produces parity-violating contributions to the pion angular differential cross section.
