“…However this difference does not show up in this comparison with data. The role of final state interaction has been discussed by several authors [35,36]. In their works [35,36] the MiniBooNE differential cross sections function of the final pion momentum (a quantity that our approach does not calculate) are evaluated.…”

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 Q 2 distribution. Both are compatible with data.

“…This measurement is primarily sensitive to pions with kinetic energies from 20 to 400 MeV produced by ∆(1232) decays. The kinetic energy spectrum of charged pions reported by MiniBooNE does not show the suppression of pions predicted by beam-based models of FSI [24][25][26], particularly around 160 MeV where the total pion-carbon cross section peaks and pion absorption is greatest. At present, oscillation experiments must account for this discrepancy by assigning large systematic errors on the size of pion FSI [27].…”

Charged pion production via charged-current νµ interactions on plastic scintillator (CH) is studied using the MINERvA detector exposed to the NuMI wideband neutrino beam at Fermilab. Events with hadronic invariant mass W < 1.4 GeV and W < 1.8 GeV are selected in separate analyses: the lower W cut isolates single pion production, which is expected to occur primarily through the ∆(1232) resonance, while results from the higher cut include the effects of higher resonances. Cross sections as functions of pion angle and kinetic energy are compared to predictions from theoretical calculations and generator-based models for neutrinos ranging in energy from 1.5-10 GeV. The data are best described by calculations which include significant contributions from pion intranuclear rescattering. These measurements constrain the primary interaction rate and the role of final state interactions in pion production, both of which need to be well understood by neutrino oscillation experiments.

“…The most comprehensive approach till now, with both a quite complete microscopic description of the pion production on the nucleon 1 and the nuclear medium effects, can be found in Ref. [20]. There, the Giessen Boltzmann-Uehling-Uhlenbeck (GiBUU) model is used finding that total cross sections measured by MiniBooNE are higher than theoretical ones for neutrino energies above 0.8 ∼ 0.9 GeV and obtaining also some discrepancies in the differential cross sections.…”

Singleπproduction in neutrino-nucleus scattering

We study 1π production in both charged and neutral current neutrino nucleus scattering for neutrino energies below 2 GeV. We use a theoretical model for one pion production at the nucleon level that we correct for medium effects. The results are incorporated into a cascade program that apart from production also includes the pion final state interaction inside the nucleus. Besides, in some specific channels coherent π production is also possible and we evaluate its contribution as well. Our results for total and differential cross sections are compared with recent data from the MiniBooNE Collaboration. The model provides an overall acceptable description of data, better for N C than for CC channels, although theory is systematically below data. Differential cross sections, folded with the full neutrino flux, show that most of the missing pions lie in the forward direction and at high energies.
