Named Muon g-2, the experiment was conducted at FermiLab in Illinois.

Subatomic, electrically charged particles known as muons

are created and trapped inside the “donut”—a huge accelerator similar to the Large Hadron Collider—on a powerful magnetic racetrack where they travel near the speed of light.

The muons wobble as they go, interacting with other particles,

but they didn’t wobble in the way researchers expected, indicating the influence of an unknown particle or force.

Roberts reports that the experiment confirmed the results of an earlier test that challenges the Standard Model of physics.

Now, about that donut. Electronics and circuitry developed here at BU play an integral part in its operation.

The machine was transported from the Northeast to the Midwest

and is so large it had to travel around Florida, up the Mississippi, and along a shutdown interstate in Illinois.
