Abstract
The results of a sterile neutrino search using eight years of data from the IceCube Neutrino Observatory are presented. A total of 305 735 muon neutrino events are analyzed in reconstructed energy-zenith space to test for signatures of a matter-enhanced oscillation that would occur given a sterile neutrino state with a mass-squared differences between 0.01 and . The best-fit point is found to be at and , which is consistent with the no sterile neutrino hypothesis with a value of 8.0%.

No Sterile Neutrinos from Eight Years of IceCube
Published 30 September 2020
An analysis of more than 300,000 muon neutrino detections provides no evidence of sterile neutrinos—a finding at odds with other experiments.
