Researchers dedicated to a decades-long quest to measure the magnetic properties of the subatomic muon particle have won one of this year’s US$3-million Breakthrough prizes. The results seemingly confirm the standard model of particle physics, but team member David Hertzog, a nuclear physicist at the University of Washington in Seattle, says that it is not yet “game over”, with mysteries remaining around why two independent methods used to calculate the model’s predictions disagree drastically .…
