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

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, ...

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 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.
