Extraction of Neutrino Flux with the Low $\nu$ Method at MiniBooNE Energies

Understand

We describe the application of the `low-$\nu$' method to the extraction of the neutrino flux at MiniBooNE energies.

• As an example, we extract the relative energy dependence of the flux from published MiniBooNE quasielastic scattering cross sections with $\nu < 0.2$ GeV and $\nu < 0.1$ GeV (here $\nu$ is the energy transfer to the target).
• We find that the flux extracted from the `low-$\nu$' cross sections is consistent with the nominal flux used by MiniBooNE.
• We fit the MiniBooNE cross sections over the entire kinematic range to various parametrizations of the axial form factor.
