When the results of an experiment don't match predictions made by the best theory of the day, something is off. Fifteen years ago, physicists at Brookhaven National Laboratory discovered something ...

Fermilab experiment to measure muon magnetic moment more precisely might reveal unknown virtual particles. In the search for new physics, experiments based on high-energy collisions inside massive ...

Magnetic moment is an intrinsic property of a particle with spin, arising from interaction between the particle and a magnet or other object with a magnetic field. Like mass and electric charge, ...
