Abstract
The SciBooNE and MiniBooNE collaborations report the results of a \nu_\mu disappearance search in the \Delta m^2 region of 0.5-40 eV^2. The neutrino rate as measured by the SciBooNE tracking detectors is used to constrain the rate at the MiniBooNE Cherenkov detector in the first joint analysis of data from both collaborations. Two separate analyses of the combined data samples set 90% confidence level (CL) limits on \nu_\mu disappearance in the 0.5-40 eV^2 \Delta m^2 region, with an improvement over previous experimental constraints between 10 and 30 eV^2.
