Using a novel particle accelerator, a group for the first time have observed a phenomenon called muon ionization cooling–an event that could give researchers a better understanding of matter and the ...

Here’s how physicists calculate g-2, the value that will determine whether the muon is giving us a sign of new physics. Like racecars on a track, thousands of particles called muons zip around an ...

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 ...

Predicting the numerical value of the magnetic moment of the muon is one of the most challenging calculations in high-energy physics. Some physicists spend the bulk of their careers improving the ...

In the world of particle physics, you are never alone — quite literally. Every moment there is an invisible rainstorm of subatomic particles falling down on us from space. Unlike the kind of matter we ...

Physicists should be ecstatic right now. Taken at face value, the surprisingly strong magnetism of the elementary particles called muons, revealed by an experiment this month, suggests that the ...

The muon’s mysteries continue to leave physicists spellbound. Last year, an experiment suggested that the elementary particle had inexplicably strong magnetism, possibly breaking a decades-long streak ...

Scientists may have observed the Higgs boson doing a new trick: creating pairs of muons. When the Higgs boson was discovered at the Large Hadron Collider (LHC) in 2012, it was the final piece of ...

Building experimental evidence suggests that the electron, muon and tau may feel different forces. When the tau lepton was discovered in the 1970s, it didn’t resolve any outstanding mysteries—it ...
