Comparison of a new Delta resonance production model with electron and neutrino data

Abstract

We consider resonance production by neutrinos focusing on the dominant resonance $P_{33}$ at low energies with a detailed discussion of its form factors. The results are presented for free nucleon targets. The $\hat{I}”$ resonance is described by two form factors $C_3^V$ and $C_5^A$ and its differential cross sections are compared with experimental data. Further, we apply this approach to the electroproduction case and calculate its differential cross sections which are compared with electroproduction experimental data. Our approach to the analysis of $\hat{I}”$ resonance is particularly simple and self-contained such that it could be helpful for the physical interpretation.
