CMS researchers observe quantum entanglement in top quark–antiquark pairs, revealing new insights into quantum behaviour at the smallest scales Quantum entanglement is a fascinating phenomenon in ...

Time evolution of the quark-antiquark pair produced by high-energy particle collisions. The pair separates in space, producing additional quark-antiquark pairs, but it still maintains the quantum ...

Some friendly competition led up to the first discovery of entanglement at the Large Hadron Collider. Andy Jung had a secret. And he wasn’t the only one. Jung and many of his colleagues on the CMS ...

Heavy-ion physics is a dynamic field that investigates the behaviour of matter under extreme conditions by colliding nuclei at relativistic speeds. Such collisions create a short-lived, ...

Ninety million times a year, when protons crash together at the Large Hadron Collider (LHC), they produce, in their wreckage, a top quark and an anti-top quark, the heaviest known elementary particles ...
