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 ...

Proton collisions at the LHC appear wildly chaotic, but new data reveal a surprising underlying order. The findings confirm that a basic rule of quantum mechanics holds true even in extreme particle ...

China’s decision to halt work on what was meant to be the world’s largest particle accelerator has reshaped the global race ...

New experimental results show particles called muons can be corralled into beams suitable for high-energy collisions, paving the way for new physics. New experimental results show particles called ...

We're getting closer to full power: For the first time in two years, after significant upgrades and repairs, the Large Hadron Collider is now delivering proton-to-proton collisions for four of CERN's ...
