Abstract
The semiexclusive channel is analyzed using MINERvA exposed to the low-energy NuMI beam with spectral peak at . Differential cross sections for muon momentum and production angle, kinetic energy and production angle, and for squared four-momentum transfer are reported, and the cross section is obtained over the range . Results are compared to GENIE and NuWro predictions and to published MINERvA cross sections for charged-current production by neutrinos. Disagreements between data and simulation are observed at very low and relatively high values for muon angle and for that may reflect shortfalls in modeling of interactions on carbon. For 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 mesons, the invariant mass distribution is obtained, and the decay polar and azimuthal angle distributions in the rest frame of the system are measured in the region of production, .
