When two high-energy protons from the counter-circulating beams of the LHC collide, the entropy of the interacting quarks and gluons is virtually identical to the entropy of the hadrons that ...

Following a two-year shutdown for maintenance and upgrades, Ned Stafford looks at how the LHC has been improved to allow researchers to hunt for new particles Power boost The upgrade and maintenance ...

Inside the most powerful particle colliders on Earth, protons slam together at nearly the speed of light, shredding matter into a short‑lived fireball of quarks and gluons. For years, physicists ...
