Scientists have measured the magnetic moment of the muon to unprecedented precision, more than doubling the previous record. Physicists from the Muon g-2 Collaboration cycled muons, known as "heavy ...

A mysterious magnetic property of subatomic particles called muons hints that new fundamental particles may be lurking undiscovered. In a painstakingly precise experiment, muons’ gyrations within a ...

The Muon g-2 electromagnet at Fermilab, ready to receive a beam of muon particles. The ring generates a uniform magnetic field scientists will use to study properties of the muon in a hunt for ...

Predicting the numerical value of the magnetic moment of the muon is one of the most challenging calculations in high-energy physics. Some physicists spend the bulk of their careers improving the ...

When hundreds of physicists gathered on a Zoom call in late February to discuss their experiment’s results, none of them knew what they had found. Like doctors in a clinical trial, the researchers at ...

Here’s how physicists calculate g-2, the value that will determine whether the muon is giving us a sign of new physics. Like racecars on a track, thousands of particles called muons zip around an ...

Can you weigh an elephant before and after it picks up a one-rupee coin, and tell the difference? You can if the measurement is precise. To detect a 4-gram coin on a 4-tonne creature, the scales must ...

Physicists have spent the last 20 years pondering an apparent discrepancy between experimental results and theoretical predictions for the magnetic properties of the muon, the electron’s heavier ...
