IceCube Experiments (IMAGE) University of Copenhagen - Niels Bohr Institute Caption The IceCube result excludes a sterile neutrino with a mass difference (Δm^2) and oscillation with the conventional neutrinos (θ_{24}) values to the right of the red line. The IceCube exclusion rules outs the allowed region from other experiments which have 'hints' of a sterile neutrino; shown as the blue regions.
