Fermilab | Muon g-2
The Muon g-2 experiment at Fermilab has made the worldâs most precise measurement yet of the anomalous magnetic moment of the muon. It improves the precision of their previous result by a factor of ...

Why muons?
The muon, like its relative the electron, is a point-like particle, meaning that it has no composite parts. Whereas the energy of a composite particle, such as a proton, is really the sum o...

How do we measure g-2?
A beam of muons with aligned spins is directed into a storage ring that has a very precisely known magnetic field. As the beam goes around this storage ring, the muons' spins wo...

Take a 360-degree virtual tour of the Muon g-2 experiment
The Muon g-2 experiment at Fermilab studies subatomic particles called muons by placing them into a remarkably uniform magnetic field. The pri...
