Description
The superscaling SuSAv2 model, that was successfully used to explain electron scattering data in the quasielastic (QE) as well as in the high inelastic regions (see [1] and refs. therein), is here extended to charged-current neutrino scattering processes on nuclei. We provide a detailed description of the Delta nucleon resonance and compare our predictions based on the pure Relativistic Fermi Gas (RFG) and SuSAv2 scaling functions with previous results obtained using a Delta scaling function fitted to the analysis of (e,e’) data. The model is extended to the complete neutrino inelastic spectrum, resonant, non-resonant and deep inelastic scattering (DIS), by considering different parametrizations of the weak inelastic single-nucleon structure functions and a Parton Distribution Function (PDF) model. Our predictions, including also two-particle two-hole contributions, are compared with data taken by the T2K collaboration.
