  • We extend and review our analysis of the nucleon → Δ(1232) transition electroweak form factors from Ref. [1]. New fit of the Δ(1232) vector form factors to electron-proton scattering F2 structure function is introduced as well, leading to results different from the popular parametrization of Ref. [2]. A clear model dependence of the extracted parameters emerges. Fit to neutrino scattering data is performed in all available isospin channels. The resulting axial mass is MAΔ=0.85−0.08+0.09(GeV… CONTINUE READING
