Neutrino–oxygen CC0 π scattering in the SuSAv2-MEC model

We present the predictions of the joint SuperScaling Approach version 2—Meson Exchange Currents model for the double differential charged-current muonic neutrino (antineutrino) cross section on water for the T2K neutrino (antineutrino) beam. We validate our model by comparing with the available inclusive electron scattering data on oxygen and compare our predictions with the recent T2K ν μ - 16 O data (Abe et al (T2K Collaboration) 2018 Phys. Rev. D 97 012001), finding good agreement at all kinematics. We show that the results are very similar to those obtained for ν μ - 12 C scattering, except at low energies, and we comment on the origin of this difference. A factorized spectral function model of 16 O is also included for purposes of comparison.
