High-energy cosmic neutrino confirms long-predicted resonance in the weak interaction
On 6 December 2016, an extremely high-energy neutrino was measured in the IceCube Neutrino Observatory in Antarctica, which allows surprising conclusions to be drawn about fundamental particle physics. The energy of 6.3 peta-electronvolts alone is record-breaking and points to an origin outside our solar system. This event also confirms for the first time a particle reaction predicted by Nobel Prize winner Sheldon Glashow as early as 1960. The research results of the international team were published today under the title "Detection of a particle shower at the Glashow resonance with IceCube" in the journal "Nature". RWTH scientists from the 3. Physics Institute B were also significantly involved in this work.
