A new calculation helps narrow down the mass of the W boson, one of the heaviest fundamental particles in the universe ...

Scientists working on Fermilab's Muon g-2 experiment released the world's most precise measurement yet of the magnetic moment of the muon, bringing particle physics closer to the ultimate showdown ...

A special class of sensors leverages quantum properties to measure tiny signals at levels that would be impossible using ...

Physicists now have a brand-new measurement of a property of the muon called the anomalous magnetic moment that improves the precision of their previous result by a factor of 2. An international ...

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 experiment's third and final result, based on the last three years of data, is in perfect agreement with previous results, further solidifying the experimental world average. Scientists working on ...

The simplicity of a hydrogen atom makes it an ideal model for studying atomic structure and interactions. Yet, despite the ...
