Improved constraint on the M i N e Rν A medium energy neutrino flux using ν ¯ e- → ν ¯ e- data

Processes with precisely known cross sections, like neutrino-electron elastic scattering (ve- -ve-) and inverse muon decay (vise- -is-ve) have been used by MINERvA to constrain the uncertainty on the neutrinos at the main injector (NuMI) neutrino beam flu
