Physicists at CERN’s Large Hadron Collider have uncovered new hints that certain particle decays may not behave as the ...

The largest-ever survey of physicists from around the world—released today—shows a distinct lack of consensus across many of ...

For the past half century or so, a theory known by the understated name of the Standard Model has dominated the field of particle physics. This theory provides us with a detailed description of the 17 ...

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 ...

From the outside, the high-speed collisions of atomic nuclei inside particle accelerators like CERN’s Large Hadron Collider (LHC) may seem like they have very little in common with more mundane ...

The universe may not be perfectly uniform after all, a new series of papers hints. If confirmed, this could upend a nearly ...

In 1930, a young physicist named Carl D. Anderson was tasked by his mentor with measuring the energies of cosmic rays—particles arriving at high speed from outer space. Anderson built an improved ...

A mysterious magnetic property of subatomic particles called muons hints that new fundamental particles may be lurking undiscovered. In a painstakingly precise experiment, muons’ gyrations within a ...

Survey shows division: The largest-ever poll of physicists found scant agreement on core theories, including the Standard Model of cosmology. Collider hints anomaly: Rare B meson decays at CERN's LHC ...
