Building experimental evidence suggests that the electron, muon and tau may feel different forces.
The new measurement from the Muon g-2 experiment at Fermilab strongly agrees with the value found at Brookhaven and diverges from theory with the most precise measurement to date.
A super-precise experiment at Fermilab is carefully analyzing every detail of the muon’s magnetic moment.
Here’s how physicists calculate g-2, the value that will determine whether the muon is giving us a sign of new physics.
The discovery of the muon originally confounded physicists. Today international experiments are using the previously perplexing particle to gain a new understanding of our world.
Physicists often find thrifty, ingenious ways to reuse equipment and resources.
The Muon g-2 experiment has begun its search for phantom particles with its well-traveled electromagnet.
For a little over a month this summer, a huge electromagnet slowly journeyed from New York to Illinois, offering great photo opportunities along the way.
The 50-foot-wide electromagnet for the Muon g-2 experiment has completed its five-week journey from New York to Illinois.
Symmetry writer Andre Salles tells you everything you always wanted to know about moving a gigantic electromagnet but were afraid to ask.
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.
