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.

abstract
We investigate the double differential neutrino-carbon quasielastic cross sections as measured by the MiniBooNE experiment. Our present treatment incorporates relativistic corrections in the nuclear response functions and includes the multinucleon component. We confirm our previous conclusion that it is possible to account for all the data without any modification of the axial mass. We also introduce the Q^2 distribution for charged and neutral current. The data point at a sizable multinucleon component beside the genuine quasielastic peak. They are also indicative of the collective character of the nuclear response, of interest for hadronic physics.

CP-violation or Nuclear Excitation: Reviewing the Role of Neutrino Interaction Model Uncertainties on Accelerator-Based Neutrino Oscillation Measurements
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.
