First Anti-Neutrinno Oscillation Results from MiniBooNE

The first MiniBooNE neutrino oscillation results published April of 2007 ruled out the simple two neutrino oscillation hypothesis of the LSND experiment. However, MiniBooNE unexpectedly observes a significant excess of electron-like events below a reconstructed neutrino energy of 475 MeV. For the last two years MinibooNE has been running in anti-neutrino mode. The anti-electron neutrino data sample can shed light on the neutrino low energy excess since they share many of the same systematic errors. As well, a search for oscillation at higher energy can be performed. Updated results of the neutrino low energy excess and new anti-neutrino oscillation results will be presented.
