Details

In normal nuclear matter, quarks and gluons are confined within particles such as protons. However, under extreme temperatures and densities, quarks and gluons may behave as free particles in a state known as the Quark Gluon Plasma (QGP). Such extreme conditions existed immediately after the Big Bang and can be recreated in high energy collisions of heavy nuclei at the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Lab in New York and the Large Hadron Collider (LHC) at CERN in Switzerland. The properties of the QGP can be studied by colliding heavy ions such as gold and lead at relativistic speeds and comparing measurements in such events to those in proton-proton collisions. In addition to bulk properties such as temperature and flow, high momentum particles produced in the early stages of the collisions can serve as probes of the QGP. Quantifying the properties of the QGP enhances our understanding of Quantum Chromodynamics, the theory of the strong force which binds the nucleus together.
