Superscaling and charge-changing neutrino scattering from nuclei in the Δ region beyond the relativistic Fermi gas model

Abstract

The superscaling analysis using the scaling function obtained within the coherent density fluctuation model is extended to calculate charge-changing neutrino and antineutrino scattering on $^{12}\mathrm{C}$ at energies from 1 to 2 GeV not only in the quasielastic but also in the $\ensuremath{\Delta}$ excitation region. The results are compared with those obtained using the scaling functions from the relativistic Fermi gas model and from the superscaling analysis of inclusive scattering of electrons from nuclei.
