Muons are getting a move on. In a step toward new types of particle physics experiments, scientists cooled and then accelerated a beam of muons. The subatomic particles, heavy cousins of electrons, ...

Muons galore: why is Pierre Auger seeing more muons than expected? (Courtesy: Pierre Auger Observatory) Significantly more muons appear to be created in cosmic-ray showers than are predicted by models ...

The next generation of atom smasher could be a 100-kilometer-round ring, costing over $10 billion, with no promise of finding something as glamorous as last decade’s Higgs boson. But does the future ...

From protons to electrons to atomic nuclei, physicists love smashing tiny stuff together. And soon, they may have an even better way to get their kicks. A new experiment raises prospects for building ...

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 ...

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 ...

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 ...

Particle deflector: the paths of muons are affected by the huge voltages found in thunderclouds. (Courtesy: iStock/prudkov) A thundercloud with a record-breaking voltage of 1.3 GV has been observed by ...

You might think that particle physicists would be sad when an experiment comes up with different results than their theory would predict, but nothing brightens up a field like unexplained phenomena.
