| This dissertation presents a search for numu, and numu disappearance with the MiniBooNE experiment in the Deltam2 region of a few eV 2. Disappearance measurements in this oscillation region constrain sterile neutrino models and CPT violation in the lepton sector. Fits to the shape of the numu, and numu, energy spectra reveal no evidence for disappearance in either mode. This is the first test of numu, disappearance between Deltam2 = 0.1--10 eV 2. In addition, prospects for performing a joint analysis using the SciBooNE detector in conjunction with MiniBooNE are discussed. |
