HIGH-ENERGY PHYSICS:
Muon Experiment Challenges Reigning Model of Particles

As Science went to press, physicists were preparing to present results of a long-awaited experiment--results that contradict what the Standard Model of particle physics predicts. Barring a statistical fluke or undetected systematic error--both real possibilities--the observations appear to mark the best evidence yet that the Standard Model is just a province of a larger, shadowy realm: supersymmetry.
