Experimental Particle Research Suggests Standard Model Violations

An article in Scientific American reports that recent experiments carried out in the United States, Switzerland and Japan suggest that three particles: electrons, muons and tau leptons maybe violating the Standard Model, which scientists say could lead to a huge and revolutionary shakeup in the world of physics

“The evidence comes from electrons and their more massive cousins, muons and tau leptons. According to the Standard Model, these three particles should behave like differently sized but otherwise identical triplets. But three experiments have produced growing evidence—including results announced in just the last few months—that the particles react differently to some as-yet mysterious influence. The findings are not yet conclusive, but if they hold up, “it would be a complete revolution,” says California Institute of Technology theorist Mark Wise.”
