Inclusive and pion production neutrino-nucleus cross sections

Abstract

We analyze the experimental data on the inclusive double-differential cross section by neutrinos charged current, measured by T2K, with the same model which was successful for the MiniBooNE quasielastic cross sections. As in our previous analysis the multinucleon component is needed in order to reproduce the data. For the total cross section, our evaluation is smaller than the SciBooNE data above 1 GeV. This indicates the opening of a new channel not included in our evaluation, presumably the two-pion-emission channel. We also check that our description holds for the exclusive single-pion-production channel by confronting our evaluation with the MiniBooNE double-differential cross section for a single charged pion and the Q2 distribution. Both are compatible with the data. © 2014 American Physical Society.
