Researchers at the Large Hadron Collider have detected one of the rarest particle decays seen in nature. The finding deals a significant blow to the theory of physics known as supersymmetry. Many researchers had hoped the LHC would have confirmed this by now. Supersymmetry, or Susy, has gained popularity as a way to explain some of the inconsistencies in the traditional theory of subatomic physics known as the Standard Model. The new observation, reported at the Hadron Collider Physics conference in Kyoto and outlined in an as-yet unpublished paper, is not consistent with many of the most likely models of Susy.
