We report results of a search for oscillations involving a light sterile neutrino over distances of 1.04 and 735 km in a ?µ-dominated beam with a peak energy of 3 GeV. The data, from an exposure of 10.56 × 10^20 protons on target, are analyzed using a phenomenological model with one sterile neutrino. We constrain the mixing parameters ?24 and ?m41^2 and set limits on parameters of the four-dimensional Pontecorvo-Maki- Nakagawa-Sakata matrix, |Uµ4|2 and |Ut4|2, under the assumption that mixing between ?e and ?s is negligible (|Ue4|^2 = 0). No evidence for ?µ ? ?s transitions is found and we set a world-leading limit on ?24 for values of ?m41^2 ? 1 eV^2.
