Influence of axial mass and strange axial form factor on neutrino-nucleus scattering in the quasielastic region

초록

We study the effects of the strange axial form factor and axial mass on both neutral- and charged-current reactions in the quasielastic region within the framework of a relativistic single-particle model. For this purpose, we calculate the differential cross section, the separated cross sections associated with the longitudinal and transverse response functions, the asymmetry for the neutral-current reaction, and the various ratios of the neutral-to charged-current reactions. The calculations are performed for a C-12 target at specific incident neutrino (antineutrino) energies of 0.5 and 1.5 GeV, or with the flux-averaged incident energies of the MiniBooNE experiment. Then, we discuss the dependence of the cross sections, asymmetry, and ratios on the axial mass and strange axial form factor. Finally, we compare our calculations with the MiniBooNE experimental data.
