No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

A new measurement technique used by CERN’s BASE collaboration has constrained the magnetic moment of the antiproton with parts-per-billion precision – a huge improvement over the roughly ...

Quantum mechanics has a reputation that precedes it. Virtually everyone who has bumped up against the quantum realm, whether in a physics class, in the lab, or in popular science writing, is left ...

After a two-decade wait that included a long struggle for funding and a move halfway across a continent, a rebooted experiment on the muon — a particle similar to the electron but heavier and unstable ...

Zoltan Fodor receives funding from DFG, BMBF. 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 ...
