The LHCb collaboration at CERN has confirmed the observation of an ultra-rare particle decay that has puzzled physicists for ...

The magnum opus of particle physics is far from complete, requiring physicists to devise many alternatives—some weirder than ...

The Large Hadron Collider has discovered a new particle, the 80th identified so far by the world's most powerful particle smasher, Europe's CERN physics laboratory announced Tuesday.

Britain is preparing to cancel its contribution to one of the Large Hadron Collider's next major upgrades.

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 have found that an elementary particle called the W boson appears to be 0.1 percent too heavy—a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...
