This poster presents the first measurement of electron neutrinos from the Fermilab Booster Neutrino Beam with the MicroBooNE experiment, and investigates the low energy excess of electromagnetic activity observed by the MiniBooNE experiment. MicroBooNE is a liquid argon time projection chamber (LArTPC) collecting data in the same neutrino beam as MiniBooNE. LArTPC detectors provide detailed topological images of neutrino interactions and calorimetric information about the particles produced in these interactions. This analysis uses the unique capabilities of LArTPCs to perform a high purity measurement of electron neutrinos across a broad range of signal topologies and energies. Background and modeling uncertainties are constrained using data-driven measurements of muon neutrino charged and neutral current interactions. These allow this analysis to test the electron neutrino hypothesis of the MiniBooNE low energy excess. An overview of the analysis strategy and results are presented.
MicroBooNE measures low energy electron neutrinos to test the MiniBooNE anomaly.
