The Muon g-2 electromagnet at Fermilab, ready to receive a beam of muon particles. This experiment began in 2017 and will take data for a total of 3 years, reducing the uncertainties significantly.

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 ...

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 ...

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 ...

Due to government shutdown restrictions currently in place in the US, the researchers who headed up this study have not been able to comment on their work Laser plasma acceleration (LPA) may be used ...

Although tiny, a proton takes up a finite amount of space, enough to fit three quarks, a host of virtual particles, and their associated gluons. The size of a proton’s radius is determined by these ...

The muon—the short-lived cousin of the electron—could be the key to understanding relationships between other fundamental particles. And it holds a mystery all its own. In the 1930s, scientists ...
