| Popis: | The MiniBooNE neutrino oscillation search experiment at Fermilab has recently updated results from a search for $\bar\nu_\mu \rightarrow \bar\nu_e$ 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 $\bar\nu_\mu \rightarrow \bar\nu_e$ oscillations over a background only hypothesis at 91.1% confidence level in the energy range 475 $< E_\nu< $3000 MeV. Comment: 4 pages, 6 figures, talk given at NuFact 2011, XIIIth InternationalWorkshop on Neutrino Factories, Super beams and Beta beams, CERN/UNIGE, Geneva, Switzerland, August 1-6, 2011 |
