Abstract: We report constraints on antineutrino oscillation parameters that were obtained by using the two MINOS detectors to measure the 7% muon antineutrino component of the NuMI neutrino beam. In the Far Detector, we select 130 events in the charged-current muon antineutrino sample, compared to a prediction of 136.4±11.7(stat)+10.2−8.9(syst) events under the assumption |Δm⎯⎯⎯2|=2.32×10−3  eV2, sin2(2θ⎯⎯)=1.0. Assuming no oscillations occur at the Near Detector baseline, a fit to the two-flavor oscillation approximation constrains |Δm⎯⎯⎯2|<3.37×10−3  eV2 at the 90% confidence level with sin2(2θ⎯⎯)=1.0.
