For experimental physicists, the latest measurement of the muon is the best of times. For theorists there's still work to do.

A recent experiment at Fermilab has delivered intriguing results that challenge standard predictions, adding fuel to the ...

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 ...

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 ...

A prototype of a device that could someday detect nukes through layers of steel just passed its first test. The detector, which uses technology that was developed for particle physics experiments at ...

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 ...

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 ...
