Title: New constraints on sterile neutrino oscillations from MINOS, Daya Bay, and Bugey-3.

Speaker: Adam Aurisano, University of Cincinnati
 

Abstract: Three-flavor neutrino oscillations have successfully explained a wide range of neutrino oscillation data. However, anomalous results, such as the electron-antineutrino appearance excesses seen by LSND and MiniBooNE, can be explained by the addition of a sterile neutrino at a larger mass scale than the existing active neutrino mass states. In this talk, I will describe two new searches for sterile neutrino oscillations. The first search looks for evidence of disappearance in the charged-current muon-neutrino and the neutral-current samples collected by the MINOS detectors exposed to the primarily muon-neutrino NuMI beam. The second search looks for evidence of disappearance in the electron-antineutrino sample collected by the Daya Bay detectors exposed to neutrinos produced by nuclear reactors. Finally, I will discuss the combination of the results of the MINOS and Daya Bay searches with results from the Bugey-3 reactor experiment to produce constraints on sterile neutrino mixing directly comparable with LSND and MiniBooNE.
