“…It is used to examine the decay angular distribution of the π 0 p system in the candidate ∆(1232) + rest frame. In bubble chamber experiments of the 1970s and 1980s, polarization effects were observed in the pure I = 3/2 channel ν µ p → µ − pπ + [18,19,21,36] and in the mixed isospin channelν µ p → µ + pπ − [36]. This work reports the first-ever measurement of the decay polar and azimuthal angles θ and φ for the mixed isospin reaction (2).…”

The semi-exclusive channel νµ +CH → µ − π 0 +nucleon(s) is analyzed using MINERvA exposed to the low-energy NuMI νµ beam with spectral peak at Eν 3 GeV. Differential cross sections for muon momentum and production angle, π 0 kinetic energy and production angle, and for squared fourmomentum transfer are reported, and the cross section σ(Eν ) is obtained over the range 1.5 GeV ≤ Eν < 20 GeV. Results are compared to GENIE and NuWro predictions and to published MINERvA cross sections for charged current π + (π 0 ) production by νµ(νµ) neutrinos. Disagreements between data and simulation are observed at very low and relatively high values for muon angle and for Q 2 that may reflect shortfalls in modeling of interactions on carbon. For π 0 kinematic distributions however, the data are consistent with the simulation and provide support for generator treatments of pion intranuclear scattering. Using signal-event subsamples that have reconstructed protons as well as π 0 mesons, the pπ 0 invariant mass distribution is obtained, and the decay polar and azimuthal angle distributions in the rest frame of the pπ 0 system are measured in the region of ∆(1232) + production, W < 1.4 GeV.

Methods to determine neutrino flux at low energies

We investigate the "low-ν" method (developed by the CCFR/NUTEV collaborations) to determine the neutrino flux in a wide band neutrino beam at very low energies, a region of interest to neutrino oscillations experiments. Events with low hadronic final state energy ν < ν cut (of 1, 2 and 5 GeV) were used by the MINOS collaboration to determine the neutrino flux in their measurements of neutrino (ν μ ) and antineutrino (ν μ ) total cross sections. The lowest ν μ energy for which the method was used in MINOS is 3.5 GeV, and the lowestν μ energy is 6 GeV. At these energies, the cross sections are dominated by inelastic processes. We investigate the application of the method to determine the neutrino flux for ν μ ,ν μ energies as low as 0.7 GeV where the cross sections are dominated by quasielastic scattering and Δ(1232) resonance production. We find that the method can be extended to low energies by using ν cut values of 0.25 and 0.50 GeV, which are feasible in fully active neutrino detectors such as MINERvA.

“…The earliest neutrino CC1π + measurements used hydrogen or deuterium targets [12][13][14][15][16] or reported neutrino-nucleon cross sections extracted from nuclear target data by model-dependent corrections [17][18][19]. These data, particularly the ANL [13] and BNL [14] data, are used to constrain the neutrino-nucleon pion production models contained in event generators, but these constraints are fairly weak because the ANL and BNL measurements differ by up to ∼40% in normalization.…”

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.
