MiniBooNE Oscillation Results 2011

Abstract

The MiniBooNE neutrino oscillation search experiment at Fermilab has recently updated results from a search for ${\bar{\nu }}_{\mu }\to {\bar{\nu }}_e$ 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 $<E_{\nu }<$ 3000 MeV. The data favor LSND-like ${\bar{\nu }}_{\mu }\to {\bar{\nu }}_e$ oscillations over a background only hypothesis at 91.1% confidence level in the energy range 475 $<E_{\nu }<$3000 MeV.
