Particle Mystery Deepens, As Physicists Confirm That the Muon Is More Magnetic Than Predicted

sciencehabit writes: A potential chink in physicists' understanding of fundamental particles and forces now looks more real. New measurements confirm a fleeting subatomic particle called the muon may be ever so slightly more magnetic than theory predicts, a team of more than 200 physicists reported this week. That small anomaly -- just 2.5 parts in 1 billion -- is a welcome threat to particle physicists' prevailing theory, the standard model, which has long explained pretty much everything they'...
