Long-Awaited Muon Measurement Boosts Evidence for New Physics

 Even if all of these efforts confirm there is new physics at work in muons, however, they will not be able to reveal what, exactly, that new physics is. The needed tool to reveal its nature may be a new collider—something many physicists are clamoring for via proposals such as the International Linear Collider and the High-Luminosity LHC. In the past few months, interest has surged around a muon collider, which multiple papers predict would guarantee physicists the ability to determine the properties of the unknown particle or force affecting the muon.

Even those who are skeptical about the significance of the new result cannot help but find a silver lining. “It is good for particle physics,” Dorigo says, “because particle physics has been dead for a little while.”
