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 ...

Physicists know that their elegant theoretical description of forces and particles – the Standard Model – must be incomplete, ...

A tiny discrepancy in particle physics has loomed for decades as an exciting possible crack in one of science’s most ...

To learn more about the nature of matter, energy, space, and time, physicists smash high-energy particles together in large accelerator machines, creating sprays of millions of particles per second of ...

A neglected force produced by neutrinos and other particles helps atomic physics measurements align with predictions of the standard model.
