Brooke Russell (Yale) "Leveraging LArTPC Technology to Definitively Resolve the MiniBooNE Anomaly – An Elctron Neutrino Appearance Search at MicroBooNE"

ABSTRACT:
MicroBooNE is a single-phase liquid argon time projection chamber (LArTPC) short-baseline accelerator neutrino experiment located at Fermilab on the Booster neutrino beamline. MicroBooNE’s foremost scientific objective is to address the low energy excess of single shower electromagnetic events seen by the precursor MiniBooNE experiment. Leveraging the fine-grained drifted ionization charge signal from particle interactions, LArTPCs provide detailed topological and calorimetric information for physics analyses. By capitalizing on the interplay between scintillation light and 3D ionization charge imaging, a high efficiency, low background analysis is in development to address MiniBooNE’s anomalous result. The status of this analysis is described.
