Analysis of the flux-integrated semi-exclusive cross sections for charged-current and neutral-current quasielastic neutrino scattering of 40Ar at energies available at the MicroBooNE.

The flux-integrated semi-exclusive differential cross sections for quasi-elastic neutrino charged-current and neutral-current scattering on argon are analyzed. The cross sections are calculated using the relativistic distorted-wave impulse approximation and compare with the recent MicroBooNE data. It was shown that the measured charged-current cros sections can be described well within the experimental uncertanties with the value of the nucleon axial form factor 1 < MA < 1.2 GeV. The contribution of the exclusive channel (νμ, μp) to the inclusive cross sections is about 50%. The ratio of cross section 40Ar(νμ, νμp) process to the cross section of 40Ar(νμ,μp) reaction is about 0.12.
