No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

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 ...

Once a surprise to physicists, these particles are useful tools inside and outside the realm of particle physics.
