“…The mean energy of the MINERνA flux is much higher than the MiniBooNE one, about 3 GeV for both ν µ and ν µ . As observed, significant contributions of the 2p-2h MEC, of the order of ∼ 35−40% (∼ 25%) at the maxima for ν µ (ν µ ), are needed in order to reproduce the experimental data that correspond to a new analysis performed by the MINERνA collaboration [37]. These data exceed by ∼ 20% the ones already presented in previous publications [8,9] that, on the other hand, were consistent with calculations based exclusively on the impulse approximation (see [39]).…”

Charged-current neutrino-nucleus reactions within the superscaling meson-exchange current approach

et al. 2016

View full text Add to dashboard Cite

We present a detailed study of charged-current (CC) neutrino-nucleus reactions in a fully relativistic framework and comparisons with recent experiments spanning an energy range from hundreds of MeV up to 100 GeV within the SuperScaling Approach, which is based on the analysis of electronnucleus scattering data and has been recently improved with the inclusion of Relativistic Mean Field theory effects. We also evaluate and discuss the impact of two-particle two-hole meson-exchange currents (2p-2h MEC) on neutrino-nucleus interactions through the analysis of two-particle two-hole axial and vector contributions to weak response functions in a fully relativistic Fermi gas. The results show a fairly good agreement with experimental data over the whole range of neutrino energies.

“…The results in Fig. 12 correspond to the MINERνA flux averaged CCQE ν µ (ν µ ) differential cross section per nucleon as a function of the reconstructed four-momentum Q 2 QE (see [37] for details). The top panel refers to ν µ − 12 C whereas the bottom panel contains predictions and data for ν µ −CH.…”

Background: A quantitative understanding of neutrino interactions with nuclei is needed for precision era neutrino long baseline experiments (MINOS, NOvA, DUNE) which all use nuclear targets. Pion production is the dominant reaction channel at the energies of these experiments.Purpose: Investigate the influence of nuclear effects on neutrino-induced pion production cross sections and compare predictions for pion-production with available data.Method: The Giessen Boltzmann-Uehling-Uhlenbeck (GiBUU) model is used for the description of all incoherent channels in neutrino-nucleus reactions.Results: Differential cross sections for charged and neutral pion production for the MINERνA neutrino and antineutrino flux are calculated. An estimate for the coherent cross section is obtained from a comparison of data with theoretical results for incoherent cross sections. The invariant mass (W ) distribution of the ∆ resonances produced is analyzed. Conclusions:Final state interactions affect the pion kinetic energy spectra significantly. The data for charged pion production at MINERνA are compatible with the results of calculations using elementary data taken from an old Argonne National Laboratory experiment. Remaining differences for charged pion production can be attributed to coherent production; the data for antineutrino induced neutral pion production, where no coherent contribution is present, are reproduced quite well. The analysis of W -distributions shows that sharp cuts on experimentally reconstructed invariant masses lead to shape-distortions of the true W distributions for nuclear targets. * Contact

Model-independent determination of the axial mass parameter in quasielastic antineutrino-nucleon scattering

Understanding the charged current quasielestic (CCQE) neutrino-nucleus interaction is important for precision studies of neutrino oscillations. The theoretical description of the interaction depends on the combination of a nuclear model with the knowledge of form factors. While the former has received considerable attention, the latter, in particular the axial form factor, is implemented using the historical dipole model. Instead, we use a model-independent approach, presented in a previous study, to analyze the muon antineutrino CCQE mineral oil data published by the MiniBooNE collaboration. We combine the cross section for scattering of antineutrinos off protons in carbon and hydrogen, using the same axial form factor for both. The extracted value of the axial mass parameter m A = 0.84 +0.12 −0.04 ± 0.11 GeV is in very good agreement with the modelindependent value extracted from MiniBooNE's neutrino data. Going beyond a oneparameter description of the axial form factor, we extract values of the axial form factor in the range of Q 2 = 0.1...1.0 GeV 2 , finding a very good agreement with the analogous extraction from the neutrino data. We discuss the implications of these results.
