The LHCb collaboration at CERN has confirmed the observation of an ultra-rare particle decay that has puzzled physicists for ...

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 ...

The standard model of particle physics is beginning to show cracks. A fundamental particle called the muon has been caught behaving strangely, and new experimental results from Fermilab in Illinois ...

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 ...

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 ...

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 ...
