The LSND neutrino oscillation experiment, performed in the 1990s at Los Alamos National Laboratory, USA, observed an excess of electron anti-neutrino events best fit by a 2-neutrinooscillation hypothesis. This result, in combination with the solar and atmospheric oscillation results, cannot be accommodated by the Standard Model. MiniBooNE is an experiment designed to confirm or refute the high-delta m^2 oscillations claimed by LSND. InMarch, 2007, MiniBooNE presented the oscillation analysis result, performed using a neutrino data sample. MiniBooNE's oscillation result employed two complementary analyses. MiniBooNE found no evidence for oscillations from 475 MeV to 3 GeV in reconstructed neutrino energy. This talk will review the oscillation result and present two new oscillation analyses: one which combines the two complementary analyses for a stronger limit, and one which combines the LSND result with the three null searches (MiniBooNE, KARMEN2, and Bugey).
