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)(-8.9)(+10.2)(syst) events under the assumption vertical bar Delta(m) over bar (2)vertical bar = 2.32 x 10(-3) eV(2), sin(2)(2 (theta) over bar = 1.0. Assuming no oscillations occur at the Near Detector baseline, a fit to the two-flavor oscillation approximation constrains vertical bar Delta m(2)vertical bar < 3.37 x 10(-3) eV(2) at the 90% confidence level with sin(2)(2<(theta)over bar>) = 1.0.
