Title: Search for sterile neutrinos mixing with muon neutrinos in MINOS

Here, we report results of a search for oscillations involving a light sterile neutrino over distances of 1.04 and 735 km in a ν 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 θ 24 and Δm 41 2 and set limits on parameters of the four-dimensional Pontecorvo-Maki-Nakagawa-Sakata matrix, |U μ4| 2 and |U τ4| 2, under the assumption that mixing between νe and νs is negligible (|U e4| 2=0). No evidence for ν μ → ν s transitions is found and we set a world-leading limit on θ 24 for values of Δm 41 2 ≲ 1 eV 2.
