Superscaling analyses of inclusive electron scattering and their extension to charge-changing neutrino cross sections in nuclei

Abstract

Superscaling analyses of inclusive electron scattering from nuclei are extended from the quasielastic processes to the delta excitation region. The calculations of (e, e′) cross sections for the target nucleus 12C at various incident electron energies are performed using scaling functions f(ψprime;) obtained in approaches going beyond the mean‐field approximation, such as the coherent density fluctuation model (CDFM) and the one based on the light‐front dynamics (LFD) method. The superscaling properties of the electron scattering are used to predict charge‐changing neutrino‐nucleus cross sections at energies from 1 to 2 GeV. The analyses make it possible to gain information about the nucleon correlation effects on both local density and nucleon momentum distributions.
