“…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.) For the channelν µ +p → µ + +π 0 +n there is only one cross-section data point, obtained with antineutrino scattering on a heavy-liquid (freon CF 3 Br) bubble chamber fill [44].…”

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.

“…A recent paper [45] presents a new fit to the reanalyzed ν µ -deuterium pion production data [43]. The best fit for GENIE 2.6.2 produces an increase in the resonant strength of about 15% and the non-resonant strength was decreased by about 50%.…”

“…The implementation of this model in the NOvA simulation is tuned to match an observed excess of events in data over simulation in bins of reconstructed three-momentum transfer [30]. Additionally, the rate of nonresonant single pion production in charged-current interactions is effectively reduced by 50%, motivated by a recent reanalysis of ν μ -deuterium pion-production data [31,32].…”

Within the multiple scattering formulation, the incoherent pion production in neutrino-deuteron reactions at energies near the ∆(1232) resonance is investigated. The calculations include an impulse term and one-loop contributions from nucleon-nucleon (N N ) and pion-nucleon (πN ) final state interactions. The input amplitudes of πN scattering and electroweak pion production reaction on the nucleon are generated from a dynamical model which describes very extensive data of πN scattering and both the electromagnetic and the weak pion production reactions on the nucleon. The N N scattering amplitudes are generated from the Bonn potential. The validity of the calculational procedures is established by giving a reasonably good description of the data of pion photo-production on the deuteron. The constructed model is then applied to predict the cross sections of ν + d → µ − + π + + n + p and ν + d → µ − + π 0 + p + p reactions. The importance of including the N N final state interactions to understand the experimental data of these neutrinodeuteron reactions is demonstrated. Our results strongly suggest that the spectator approximation used in the previous analyses to extract the pion production cross sections on the nucleon from the data on the deuteron is not valid for the ν + d → µ − + π + + n + p, but is a good approximation for ν + d → µ − + π 0 + p + p.
