At the world’s most powerful colliders, physicists are finally catching sight of particles that almost never leave a trace, a “ghost” signal that has haunted theory for decades. The detection of these ...

At CERN’s Large Hadron Collider on the edge of Geneva, scientists have reported a surprising twist in the behavior of matter. Collisions inside the 27‑kilometer ring have produced what researchers ...

Another antimatter record has been broken. In the smash-up of very energetic lead ions, researchers have uncovered evidence of the heaviest antimatter version of an atomic nucleus ever seen. In 2024, ...

In collisions at CERN’s Large Hadron Collider, hotter than the Sun’s core by a staggering margin, scientists have finally solved a long-standing mystery: how delicate particles like deuterons and ...
