A mysterious magnetic property of subatomic particles called muons hints that new fundamental particles may be lurking undiscovered. In a painstakingly precise experiment, muons’ gyrations within a ...

The unusually large Muon has threatened the Standard Model for decades, but new data parks the particle inside the cozy confines of established physics. Reading time 3 minutes Another nail may seal ...

For 30 years, the theory called the standard model has withstood all challenges to its predictions of the properties and interactions of elementary particles (SN: 7/1/95, p. 10). Despite the theory’s ...

The final result from the Muon g-2 Experiment has exceeded all expectations, achieving a precision likely to remain unmatched for generations. Yet, recent tensions in theoretical predictions have put ...

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

Inside a locked cabinet, an envelope held a number that was poised to rock the physics community, regardless of its contents. The value, a clock measurement deliberately hidden to keep physicists’ ...

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 ...
