Scientists make the first observation of a nucleus decaying into four particles after beta decay

Not all of the material around us is stable. Some materials may undergo radioactive decay to form more stable isotopes. Scientists have now observed a new decay mode for the first time. In this decay, a lighter form of oxygen, ...

Muon g-2 experiment result represents world's most precise measurement yet of the anomalous magnetic moment of the muon

The Muon g-2 collaboration has announced their much-anticipated updated measurement. The new result aligns with the collaboration's first result, announced in 2021—and it's twice as precise. In fact, it's the most precise ...
