Scientists at Antarctica's IceCube Observatory find no evidence of sterile neutrino particles

Scientists at the IceCube Neutrino Observatory in Antarctica who have been searching for mysterious particles known as sterile neutrinos have come up empty.

The results, described in Physical Review Letters, leave some troubling gaps in our understanding of particle physics and may force some theorists to reimagine a model that explains longstanding mysteries from dark matter to the universe’s missing antimatter.

“Everybody, including me and my collaborators, would have loved to see this thing,” said Francis Halzen, IceCube’s principal investigator and a theoretical physicist at the University...
