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

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

The Large High Altitude Air Shower Observatory (LHAASO) has detected PeV (1015 eV) gamma-ray emission from a pulsar wind ...

A particle accelerator that produces intense X-rays could be squeezed into a device that fits on a table, my colleagues and I have found in a new research project. The way that intense X-rays are ...

UC Santa Cruz physicist Stefano Profumo has put forward two imaginative but scientifically grounded theories that may help solve one of the biggest mysteries in physics: the origin of dark matter. In ...

Physicists have nailed a fiendishly difficult measurement — the mass of the fundamental particle the W boson. The result, from the CMS experiment at the Large Hadron Collider (LHC), is in line with ...

High above Earth, in the thin air of the Tibetan Plateau, a giant observatory ...
