Abstract	Processes with precisely known cross sections, like neutrino electron elastic scattering ($\nu e^{-} \!\rightarrow \nu e^{-}$) and inverse muon decay ($\nu_\mu e^{-} \!\rightarrow \mu^{-} \nu_e$) have been used by MINERvA to constrain the uncertainty on the NuMI neutrino beam flux. This work presents a new measurement of neutrino elastic scattering with electrons using the medium energy \numubar enhanced NuMI beam. A sample of 578 events after background subtraction is used in combination with the previous measurement on the \numu beam and the inverse muon decay measurement to reduce the uncertainty on the \numu flux in the \numu-enhanced beam from 7.6% to 3.3% and the \numubar flux in the \numubar-enhanced beam from 7.8% to 4.7%.

$An illustration of the cone algorithm used to search for hits that belong to the electromagnetic shower. The cone offset is 50 mm, the opening width is 80 mm, and cone opening angle is $10^\circ$.$ $Average energy deposition in the first four planes of the electron candidate track for events passing all other cuts after background tune (above) and the ratio of data to simulation (below). The error bars on the data points include statistical uncertainties only. The error bars on the ratio include both statistical uncertainties in data and statistical and systematic uncertainties in the simulation. Backgrounds have been tuned using the procedure described in Sec.~\ref{sec:background}. The dotted line and arrow indicated the selected sample.$ $Product of the energy of the electron candidate and the square of its scattering angle with respect to the beam direction after background tune (above) and ratio of data to simulation (below). The error bars on the data include statistical uncertainties only. The error bars on the ratio include both statistical uncertainties in data and statistical and systematic uncertainties in the simulation. The dotted line and arrow indicates the selected sample. Backgrounds have been tuned using the procedure described in Sec.~\ref{sec:background}. The cut in $Q^2_{ QE}$ is not applied here to better show the sideband region.$ Show more plots
