CHARGED-PION CROSS-SECTION MEASUREMENT FROM NOvA

NOvA is a long-baseline neutrino oscillation experiment placed in the NuMI beam at Fermi National Accelerator Laboratory (FNAL); the off-axis position of the detectors yields a narrow neutrino flux peaked at ~1.8GeV of neutrino energy. Between its Near (FNAL) and Far Detectors (Ash River, MN), NOvA aims to determine the neutrino mass hierarchy and constrain the charge-parity violation phase. In addition to oscillation measurements, the NOvA Near Detector samples are ideal for measuring neutrino-nucleus interaction cross sections--important for constraining uncertainties in oscillation analyses--with high statistics. Here, we present the status of an analysis to measure the cross section of ν_μ+ A → μ^∓ + Nπ^± + X semi-exclusive processes as a function of muon and leading-pion kinematics. This analysis is sensitive to deep inelastic scattering and resonance processes, a key region of kinematic phase space for the future DUNE experiment.
