Five hundred thousand times per second, the Electron-Ion Collider (EIC) will record a collision.

CERN engineers have transported two gleaming cryogenic “cold boxes” deep into the tunnels of the High-Luminosity Large Hadron Collider (HiLumi LHC), as part of the ambitious upgrade to the world’s ...

Artificial intelligence and machine learning are shaping major design and research decisions for the planned Electron-Ion ...

As foretold, the Relativistic Heavy Ion Collider—among the most powerful heavy-ion colliders in the world, second only to CERN’s LHC—ran its final particles and ceased operations last Friday. This is ...

The Relativistic Heavy Ion Collider (RHIC), the largest particle collider in the United States, collided its last particles in early February. RHIC is a massive accelerator ring and set of instruments ...

Just after 9 a.m. on Friday, Feb. 6, 2026, final beams of oxygen ions—oxygen atoms stripped of their electrons—circulated through the twin 2.4-mile-circumference rings of the Relativistic Heavy Ion ...

"This is the first time we have observed, for a large interval in momentum and for multiple species, this flow pattern in a subset of proton collisions in which an unusually large number of particles ...
