MiniBooNE Oscillation Results 2011

The MiniBooNE neutrino oscillation search experiment at Fermilab has recently updated results from a search for $\barν_μ\rightarrow \barν_e$ oscillations, using a data sample corresponding to $8.58 \times 10^{20}$ protons on target in anti-neutrino mode. This high statistics result represent an increase in statistics of 52% compared to result published in 2010. An excess of 57.7 $\pm$ 28.5 events is observed in the energy range 200 MeV $< E_ν<$ 3000 MeV. The data favor LSND-like $\barν_μ\rightarrow \barν_e$ oscillations over a background only hypothesis at 91.1% confidence level in the energy range 475 $< E_ν<$3000 MeV.
