A magnetic monopole is a theoretical particle with a magnetic charge. Give it an electric charge, and you get another theoretical beast, dubbed a dyon. Many “grand unified theories” of particle physics, which connect fundamental forces at high energies into a single force, predict the existence of dyons, but no experiments at particle accelerators have so far searched for these hybrid particles—until now. The MoEDAL collaboration at CERN, which was designed to search for magnetic monopoles, has just scored two firsts with the first search for dyons at the Large Hadron Collider (LHC) and, more generally, at any particle accelerator.
