MicroBooNE will collect neutrino interactions from the Booster Neutrino Beam at Fermilab. From these, MicroBooNE will explore low energy neutrino phenomena as described below.
Physics Goals
Low Energy Excess
Electron-like signal
The reconstructed energy spectrum for electron-like events, assuming the low energy excess observed by the MiniBooNE detector is due to an electron-like signal. The event predictions account for microBooNE detector efficiency, fiducial volume, and electron-photon separation efficiency. The prediction assumes data collected for 6.0e20 protons on target in neutrino mode. The error bars indicate statistical-only uncertainty.
Photon-like signal
The reconstructed energy spectrum for photon-like events, assuming the low energy excess observed by the MiniBooNE detector is due to a photon-like signal. The event predictions account for microBooNE detector efficiency, fiducial volume, and electron-photon separation efficiency. The prediction assumes data collected for 6.0e20 protons on target in neutrino mode. The error bars indicate statistical-only uncertainty.
Sterile Neutrino Oscillations
Sensitivity
MicroBooNE sensitivity for muon neutrino to electron neutrino oscillations, and comparison with MiniBooNE's allowed regions (combined neutrino and antineutrino results). The MicroBooNE sensitivity is obtained by an oscillation fit to the electron neutrino (electron-like) sample as a function of neutrino energy, with E > 200 MeV. Background and signal predictions are made using true charged current quasi-elastic electron neutrino (νeCCQE) events. The prediction assumes 6.6e20 protons on target delivered by the Booster Neutrino Beam in neutrino mode, 60 tons LAr fiducial volume, 80% reconstruction efficiency (assumed flat in energy), 3% √ E [GeV] electromagnetic shower energy resolution, and statistical and 5% flat systematic uncertainty.
Energy Spectrum
The reconstructed energy spectrum for electron neutrino (electron-like) predicted background events, and expected excess from the LSND best-fit for muon neutrino to electron neutrino oscillations. The event predictions assume 60 tons fiducial volume, 80% reconstruction efficiency, and negligible non-CCQE background. The prediction assumes data collected for 6.6e20 protons on target in neutrino mode. The error bars indicate statistical-only uncertainty.
