The semiexclusive channel. v(u) + CH -> u(-) pi(0) + nucleonds (s) is analyzed using MINERvA exposed to the low- energy NuMI v(u) beam with spectral peak at E-v similar or equal to 3 GeV. Differential cross sections for muon momentum and production angle, pi(0) kinetic energy and production angle, and for squared four- momentum transfer are reported, and the cross section sdE sigma(E-v) is obtained over the range 1.5 GeV <= E-v < 20 GeV. Results are compared to GENIE and NuWro predictions and to published MINERvA cross sections for charged-current pi+(pi(0)) _ production by v(u)(v(u)) 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 pi(0) kinematic distributions, however, the data are consistent with the simulation and provide support for generator treatments of pion intranuclear scattering. Using signalevent subsamples that have reconstructed protons as well as pi(0) mesons, the rho pi(0) invariant mass distribution is obtained, and the decay polar and azimuthal angle distributions in the rest frame of the rho pi(0) system are measured in the region of Delta(1232)(+) production, W < 1.4 GeV.
