When Fermilab physicist Steve Geer agreed to perform a calculation as part of a muon collider task force 10 years ago, he imagined he would show that the collider s technical challenges were too ...

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 ...

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, ...

Momentum is growing to build a particle collider in the United States that smashes muons — heavier cousins of electrons. The collider would follow the world’s next major accelerator, which is yet to ...
