abstract
The observation of neutrino oscillations is clear evidence for physics beyond the standard model. To make precise measurements of this phenomenon, neutrino oscillation experiments, including MiniBooNE, require an accurate description of neutrino charged current quasi-elastic (CCQE) cross sections to predict signal samples. Using a high-statistics sample of muon neutrino CCQE events, MiniBooNE finds that a simple Fermi gas model, with appropriate adjustments, accurately characterizes the CCQE events observed in a carbon-based detector. The extracted parameters include an effective axial mass, M_A^eff = 1.23+/-0.20 GeV, that describes the four-momentum dependence of the axial-vector form factor of the nucleon; and a Pauli-suppression parameter, kappa = 1.019+/-0.011. Such a modified Fermi gas model may also be used by future accelerator-based experiments measuring neutrino oscillations on nuclear targets.

Neutrino interaction model uncertainties from nuclear physics details remain a dominant systematic in oscillation analyses and will require improved modeling plus near-detector constraints to reach the precision goals of next-generation experiments.
Fixing an error in GENIE's elastic hadron-nucleus scattering code reduces large distortions in transverse kinematic imbalance distributions for quasielastic neutrino events while having milder effects on other observables.
