New Measurements of Muon’s Magnetic Moment Strengthen Evidence of New Physics

The Standard Model, scientists’ best description of the makeup and behavior of the Universe yet, very precisely predicts the g-factor of a fundamental particle called muon — a value that tells physicists how this particle behaves in a magnetic field. In the 1990s, the E821 experiment at Brookhaven National Laboratory indicated that g-2 differed from […]
