Search for an Excess of Electron Neutrino Interactions in MicroBooNE Using Multiple Final-State Topologies Abratenko, P. García Gámez, Diego MicroBooNE Collaboration We present a measurement of νe interactions from the Fermilab Booster Neutrino Beam using the MicroBooNE liquid argon time projection chamber to address the nature of the excess of low energy interactions observed by the MiniBooNE Collaboration. Three independent νe searches are performed across multiple single electron final states, including an exclusive search for two-body scattering events with a single proton, a semi-inclusive search for pionless events, and a fully inclusive search for events containing all hadronic final states.With differing signal topologies, statistics, backgrounds, reconstruction algorithms, and analysis approaches, the results are found to be either consistent with or modestly lower than the nominal νe rate expectations from the Booster Neutrino Beam and no excess of νe events is observed. 2022-07-29T10:47:59Z 2022-07-29T10:47:59Z 2022-06-13 info:eu-repo/semantics/article Abratenko, P...
