An international team of physicists has reported what it describes as the most significant deviation to date between experiment and theory in particle physics. Measurements of how muons wobble in a ...

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 50-foot-wide racetrack used to study muons traveled by barge around Florida and up the Mississippi, and then by truck across Illinois. Reidar Hahn, Fermilab About 50 years ago, physicists came up ...

Once a surprise to physicists, these particles are useful tools inside and outside the realm of particle physics. Every minute, countless muons rain down from space, passing through ...

On Wednesday, April 7, the Muon g-2 Experiment at Fermilab released its eagerly awaited first result. In the experiment, muons (like electrons but heavier) race around the 150-foot circumference ...

Muons might not behave as expected. But scientists can’t agree on what to expect. By taking stock of how the subatomic particles wobble in a magnetic field, physicists have pinned down a property of ...

Physicists may have yet another fundamental particle left to discover. When physicists at the Large Hardon Collider discovered the Higgs boson back in 2012, they’d found the last missing piece of the ...

Final results from a long-running U.S.-based experiment announced Tuesday show a tiny particle continues to act strangely — but that’s still good news for the laws of physics as we know them.

Muons are a key subatomic particle in the discovery of new physics, but after particle collision, they’re difficult to track.

The news that muons have a little extra wiggle in their step sent word buzzing around the world this spring. The Muon g-2 experiment hosted at Fermi National Accelerator Laboratory announced April 7 ...
