Abstract: A sample of charged-current single pion production events for the
semi- exclusive channel νμ + CH → μ−π0 + nucleon(s) has been obtained using neu- trino
exposures of the MINERvA detector. Differential cross sections for muon momentum, muon
production angle, pion momentum, pion production angle, and four-momentum transfer square
Q2 are reported and are compared to a GENIE-based ... read moresimulation. The cross section versus
neutrino energy is also re- ported. The effects of pion final-state interactions on these
cross sections are investigated. The effect of baryon resonance suppression at low Q2 is
exam- ined and an event re-weight used by two previous experiments is shown to improve the
data versus simulation agreement. The differential cross sections for Q2 for Eν < 4.0
GeV and Eν ≥ 4.0 GeV are examined and the shapes of these distributions are compared to
those from the experiment's ν ̄μ-CC π0 measurement. The polarization of the pπ0 system is
measured and compared to the simulation predictions. The hadronic invariant mass W
distribution is examined for evidence of resonance content, and a search is reported for
ev- idence of a two-particle two-hole (2p2h) contribution. All of the differential
cross-section measurements of this Thesis are compared with published MINERvA measurements
for νμ-CC (π+) and ν ̄μ-CC π0 processes.
