“…Normalization differences between data and predictions of event generators can be driven by cross-section uncertainties for ν µ /ν µ -induced pion production in scattering on free nucleons, as well as by flux uncertainties. The data constraining these processes are sparse, and in the case of ν µ +p → µ − +π + +p, the two bubble chamber measurements using 0.5 to ∼ 3 GeV neutrinos reported cross sections that differed by ∼ 30% in absolute normalization [41,42]. (A recent reanalysis obtains consistency between these two data sets [43] , however the generator predictions shown here have not been tuned to the results of this reanalysis.)…”

Cross sections for ν_{μ} and ν[over ¯]_{μ} induced pion production on hydrocarbon in the few-GeV region using MINERvA FERMILAB-PUB-16-228-NDCross sections for ν µ andν µ induced pion production on hydrocarbon in the few-GeV region using MINERvA Separate samples of charged-current pion production events representing two semi-inclusive channels νµ-CC(π + ) andνµ-CC(π 0 ) have been obtained using neutrino and antineutrino exposures of the MINERvA detector. Distributions in kinematic variables based upon µ ± -track reconstructions are analyzed and compared for the two samples. The differential cross sections for muon production angle, muon momentum, and four-momentum transfer Q 2 , are reported, and cross sections versus neutrino energy are obtained. Comparisons with predictions of current neutrino event generators are used to clarify the role of the ∆(1232) and higher-mass baryon resonances in CC pion production and to show the importance of pion final-state interactions. For the νµ-CC(π + ) (νµ-CC(π 0 )) sample, the absolute data rate is observed to lie below (above) the predictions of some of the event generators by amounts that are typically 1-to-2 σ. However the generators are able to reproduce the shapes of the differential cross sections for all kinematic variables of either data set.

Coherent pion production off nuclei at T2K and MiniBooNE energies revisited

As a result of a new improved fit to old bubble chamber data of the dominant axial C A 5 nucleonto-Delta form factor, and due to the relevance of this form factor for neutrino induced coherent pion production, we re-evaluate our model predictions in Phys. Rev. D 79, 013002 (2009) for different observables of the latter reaction. Central values for the total cross sections increase by 20%∼30%, while differential cross sections do not change their shape appreciably. Furthermore, we also compute the uncertainties on total, differential and flux averaged cross sections induced by the errors in the determination of C A 5 . Our new results turn out to be compatible within about 1σ with the former ones. Finally, we stress the existing tension between the recent experimental determination of the σ(CCcohπ + ) σ(NCcohπ 0 ) ratio by the SciBooNE Collaboration and the theoretical predictions.

“…For this reason, we fix its value at ρ = 0.75 ρ 0 , with ρ 0 = 17 fm −3 the saturation density. Finally, we modify the free ∆πN -decay constant (f ∆πN ) to take into account the E-dependent medium modifications: [14] where a cut in the invariant mass W < 1400 MeV is applied in both the data and the model. In (b) the cut in W is removed and BNL data [9] are also included.…”

Neutrino-induced pion production constitutes an important contribution to neutrino-nucleus scattering cross sections at intermediate energies. A deep understanding of this process is mandatory for a correct interpretation of neutrino-oscillation experiments. We aim at contributing to the ongoing effort to understand the various experimental results obtained by different collaborations in a wide range of energies. In particular, in this work we analyze recent MiniBooNE and MINERνA charged-current neutrino 1-π production data. We use a relativistic theoretical approach which accounts for resonant and non-resonant 1-π production contributions. KEYWORDS: Neutrino interactions, pion productionMost of the recent neutrino-nucleus scattering experiments work in the intermediate energy region (incident neutrino energy from some hundreds of MeV to a few GeV) where the quasielastic (QE) and the pion production channels are the dominant reaction mechanisms. A good understanding of all possible channels involved in the reaction as well as accounting for nuclear effects is essential to obtain a reliable reconstruction of the neutrino energy and, consequently, to reduce systematic uncertainties in determining neutrino oscillation parameters. The recent measurements on neutrino-induced pion production reported by the MiniBooNE [1] and MINERνA [2] collaborations show that the current theoretical predictions are not able to reproduce the experimental cross sections with the desired accuracy. Additionaly, due to the increasing energies of the new generation of experiments (HyperKamiokande and LBNF) a thorough understanding of the pion production process will be crucial in the near future.
