New IceCube detection proves 60-year-old theory
On December 6, 2016, a high-energy particle was hurtling through space at nearly the speed of light and happened to smash into an electron deep inside the South Pole’s glacial ice. The collision created a new particle, known as the W– boson. 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. The international IceCube Collaboration, including MSU scientists Claudio Kopper and Nathan Whitehorn, published this result online on March 11 in the journal Nature.
