MiniBooNE has performed a search for numu to nue oscillations with
sensitivity to Dm^2 near 1eV^2, with the goal of confirming or ruling
out the LSND numubar to nuebar oscillation signal. MiniBooNE uses a
high intensity neutrino beam at Fermilab whose average muon neutrino
energy is ~800 MeV. During its neutrino data run, MiniBooNE
accumulated 5.6E20 protons on target and more than one million
neutrino interactions in the detector. MiniBooNE performed a "blind"
analysis, where all analysis selections and fitting procedures were
determined before candidate electron neutrino events were examined.
First oscillation results will be presented.
