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 events under the assumption , . Assuming no oscillations occur at the Near Detector baseline, a fit to the two-flavor oscillation approximation constrains at the 90% confidence level with .
