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 ...

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 ...

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 ...

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

Reference Here we look at what leptons are, how they fit in the Standard Model of particle physics, and their importance in atoms and particle decay. The accelerator at FRIB started working at low ...

Everything we see around us, from the ground beneath our feet to the most remote galaxies, is made of matter. For scientists, that has long posed a problem: According to physicists’ best current ...

Scientists seeking the secrets of the universe would like to make a model that shows how all of nature’s forces and particles fit together. It would be nice to do it with Legos. But perhaps a better ...

Something is missing from the universe. Not misplaced, but structurally absent. About 85 percent of all matter in existence ...
