Search for sterile neutrino oscillations with MiniBoone

ORAL

Abstract

The MiniBooNE experiment, located at Fermilab on the Booster Neutrino Beamline, has searched for $\nu_\mu \rightarrow \nu_e$ and $\overline{\nu}_\mu \rightarrow \overline{\nu}_e$ oscillations in the range $0.1<\Delta m^2<5.0$~ev$^2$ as indicated by results from the LSND experiment. MiniBooNE completed a phase of running in April 2012 after collecting $11.3 \times 10^{20}$ protons-on-target (POT) in $\overline{\nu}_{\mu}$ mode and $6.5 \times 10^{20}$ POT in ${\nu}_{\mu}$ mode. The combination of those data sets shows a $3.8\sigma$ excess over background, consistent with that expected from the LSND result. These results along with other evidence for sterile neutrinos and plans for additional running will be presented.
