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 ...

The Standard Model. What a dull name for the most accurate scientific theory known to human beings. More than a quarter of the Nobel Prizes in physics of the last century are direct inputs to or ...

Particle physics has always proceeded in two ways, of which new particles is one. The other is by making very precise measurements that test the predictions of theories and look for deviations from ...

Physicists have spent decades treating mass as something the universe simply hands to particles, a property encoded in equations rather than explained from first principles. A new proposal argues that ...

Jason Bono was one of the researchers behind a major scientific moment — when tiny particles unexpectedly unraveled one of the most important and successful theories in physics. Bono, who earned his ...

There was a huge amount of excitement when the Higgs boson was first spotted back in 2012—a discovery that bagged the Nobel Prize for Physics in 2013. The particle completed the so-called standard ...

Quantum mechanics is baffling. On the atomic and subatomic scale, matter seems to behave in ways that we, in the macro world, would generally think of as impossible. Particles can exist in two ...
