Quasi-elastic neutrino charged-current scattering off medium-heavy nuclei: 40Ca and 40Ar

Understand

The charged-current quasi-elastic scattering of muon neutrinos on calcium and argon targets is calculated for neutrino energy up to 2.8 GeV.

• The calculations are done within the framework of the relativistic distorted-wave impulse approximation, which was earlier successfully applied to describe electron-nucleus data.
• The model is first tested against experimental data for electron scattering off calcium and then it is applied to calculate (anti)neutrino cross sections on 40Ca and 40Ar.
• We show that reduced exclusive cross sections for neutrino and electron scattering are similar.
