In September, the Large Hadron Collider (LHC) was being tuned to enable it to study proton-lead nucleus collisions for a data run next year. Eventually it ran and data was collected on the collisions ...

For the first time, scientists at the Large Hadron Collider have collided protons with lead ions, a feat that will give them insight into the quark-gluon plasma. For most of the year, two beams of ...

The ALICE Collaboration takes a step further in addressing the question of whether a quark–gluon plasma can be formed in proton–proton and proton–nucleus collisions. In the first few microseconds ...

Accelerator physicists have successfully implemented an innovative scheme for increasing proton collision rates at the Relativistic Heavy Ion Collider. More proton collisions produce more data for ...

Inside each proton or neutron there are three quarks bound by gluons. Until now, it has often been assumed that two of them form a "stable" pair known as a diquark. It seems, however, that it's the ...

Inside high-energy proton collisions, quarks and gluons briefly form a dense, boiling state before cooling into ordinary particles. Researchers expected this transition to change how disordered the ...
