provides a standard candle for measuring neutrino flux in conventional neutrino beams.
Using a total sample of 810 neutrino-electron scatters after background subtraction, the
measurement reduces the normalization uncertainty on the ν μ NuMI beam flux between 2
and 20 GeV from 7.6 to 3.9%. This is the most precise measurement of neutrino-electron
scattering to date, will reduce uncertainties on MINER ν A's absolute cross section …
