Abstract
We report the first electron neutrino cross section measurements on argon, based on data collected by the ArgoNeuT experiment running in the GeV-scale NuMI beamline at Fermilab. A flux-averaged total and a lepton angle differential cross section are extracted using 13 and events identified with fully automated selection and reconstruction. We employ electromagnetic-induced shower characterization and analysis tools developed to identify -like events among complex interaction topologies present in ArgoNeuT data ( and ). The techniques are widely applicable to searches for electron-flavor appearance at short and long baseline using liquid argon time projection chamber technology. Notably, the data-driven studies of GeV-scale interactions presented here probe an energy regime relevant for future DUNE oscillation physics.
