New SuperK Sterile Neutrino Result

Super-Kamiokande has a new result out on a search for sterile neutrinos using atmospheric neutrinos. Not surprisingly, they find no evidence of sterile neutrinos. Sterile neutrinos are theorized neutrinos that don’t interact at all but still participate in oscillations, so evidence for them is typically from anomalous measurements in the oscillation probability compared to the standard 3-neutrino model.
