Abstract

We report results of a search for oscillations involving a light sterile neutrino over distances of 1.04km and 735km in a __-dominated beam with peak energy of 3 GeV. 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 _24 and _m2 41 and set limits on parameters of the four-dimensional PMNS matrix, jU_4j2 and jU_4j2, under the assumption that mixing between _e and _s is negligible (jUe4j2 = 0). No evidence for __ ! _s transitions is found and we set a world-leading limit on _24 for values of _m2 41 . 1 eV2.
