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 ...

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 ...

But this may not be the end of the story. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. The results from one of the most hotly-anticipated ...

Physicists have spent the last 20 years pondering an apparent discrepancy between experimental results and theoretical predictions for the magnetic properties of the muon, the electron’s heavier ...

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 ...

When the results of an experiment don’t match predictions made by the best theory of the day, something is off. Fifteen years ago, physicists at Brookhaven National Laboratory discovered something ...

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’ ...

When hundreds of physicists gathered on a Zoom call in late February to discuss their experiment’s results, none of them knew what they had found. Like doctors in a clinical trial, the researchers at ...

The Muon g-2 experiment (pronounced “gee minus two”) is designed to look for tantalizing hints of physics beyond the Standard Model of particle physics. It does this by measuring the magnetic field ...

Fermilab experiment to measure muon magnetic moment more precisely might reveal unknown virtual particles. In the search for new physics, experiments based on high-energy collisions inside massive ...
