Charged-current inclusive neutrino cross sections in the SuperScaling model

[摘要] SuperScaling model (SuSA) predictions to neutrino-induced charged-current π+production in the Δ-resonance region are explored under MiniBooNE experimental conditions. The SuSA charged-current π+results are in good agreement with data on neutrino flux-averaged double-differential cross sections. The SuSA model for quasielastic scattering and its extension to the pion production region are used for predictions of charged-current inclusive neutrino- nucleus cross sections. The contribution of two-particle-two-hole vector meson-exchange current excitations is also considered within a fully relativistic model. Results are compared with the T2K experimental data for inclusive scattering.
