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 νμ-dominated beam with a peak energy of 3 GeV. Furthermore, the data, from an exposure of 10.56 × 1020 protons on target, are analyzed using a phenomenological model with one sterile neutrino. We constrain the mixing parameters θ 24 and Δ m$$2\atop{41}$$ and set limits on parameters of the four-dimensional Pontecorvo-Maki-Nakagawa-Sakata matrix, |Uμ4|2 and |Uτ 4|2, under the assumption that mixing between νe and ν s is negligible (|U e 4|2 = 0). No evidence for νμ → νs transitions is found and we set a world-leading limit on θ24 for values of Δm$$2\atop{41}$$ ≲ 1 eV2.
