Active to sterile neutrino mixing limits from neutral-current interactions in MINOS

High Energy Physics - Experiment 2015-03-19 v4

Abstract

Results are reported from a search for active to sterile neutrino oscillations in the MINOS long-baseline experiment, based on the observation of neutral-current neutrino interactions, from an exposure to the NuMI neutrino beam of 7.07×10207.07\times10^{20} protons on target. A total of 802 neutral-current event candidates is observed in the Far Detector, compared to an expected number of 754±28(stat.)±37(syst.)754\pm28\rm{(stat.)}\pm{37}\rm{(syst.)} for oscillations among three active flavors. The fraction fsf_s of disappearing \numu that may transition to νs\nu_s is found to be less than 22% at the 90% C.L.
