MicroBooNE and the Path to Resolving the MiniBooNE Low Energy Excess
Time: 2:30 pm
Place: 4274 Chamberlin Hall
Speaker: Adam Lister, Lancaster University
Abstract: MicroBooNE is a liquid argon time projection chamber which has been running in
the Booster Neutrino Beam at Fermilab since 2015. The primary goal of MicroBooNE is investigation of the excess of electromagnetic events observed by the MiniBooNE collaboration. Due to limitations of the Cherenkov-based particle identification of MiniBooNE,
this excess could be interpreted as either photon-like or electron-like. A photon-like excess would indicate that there are processes which are not well understood which could act as a background in neutrino oscillation measurements, while an electron-like
excess could indicate the presence of sterile neutrinos, the existence of which is one of the most hotly debated questions in the field. This talk will outline MicroBooNE’s strategy for investigation of the MiniBooNE low-energy excess, along with the reconstruction
and calibration work being undertaken to reduce systematic uncertainties in the the analysis of neutrino data in liquid argon.
