Description

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 has recently completed $\overline{\nu}_{\mu}$ running after collecting $11.3 \times 10^{20}$ protons-on-target (POT). Combining those results with previously collected $\nu_\mu$ data from $6.5 \times 10^{20}$ POT yields a $3.8\sigma$ excess over background, consistent with that expected from the LSND result. A proposed followup experiment, MiniBooNE+, will test the oscillation signal hypothesis by searching for final state neutrons.
