The world's largest particle accelerator has performed its first collisions, and its first beam acceleration. Progress on the giant experiment has been rapid in the four days since the Large Hadron ...

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 ...

The Large Hadron Collider is going to be shut down — not permanently, but for a pretty long time — and the famous atom ...

China's ambitious new particle accelerator was meant to pick up where the Large Hadron Collider left off, but the project was ...

Scientists at the Large Hadron Collider (LHC) at CERN have successfully transmuted lead into gold — not by alchemy, but by smashing heavy ions together at nearly the speed of light. The process, ...

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

Once a surprise to physicists, these particles are useful tools inside and outside the realm of particle physics.

A snapshot of a computer simulation showing how energy density changes over time in the collision of a lead ion with a photon emitted by another lead ion. The world’s largest and most powerful ...
