Normally, electron antineutrino would zip right through the Earth at the speed of light as if it weren’t even there. But this particle just so happened to smash into an electron deep inside the South Pole’s glacial ice, and was caught by the IceCube Neutrino Observatory. This enabled IceCube to make the first ever detection of a Glashow resonance event, a phenomenon predicted 60 years ago by Nobel laureate physicist Sheldon Glashow.
With this detection, scientists provided another confirmation of the Standard Model of particle physics. It also further demonstrated the ability of IceCube, which detects nearly massless particles called neutrinos using thousands of sensors embedded in the Antarctic ice, to do fundamental physics. The result was published March 10 in Nature.
Scientists can now study the strong force with a novel method of accessing the space between protons and neutrons within a nucleus.
