Objective: Quark-Gluon Plasma (QGP) is a primordial state of matter, which consists of interacting free quarks and gluons.
It is the free quarks and gluons situation; [[alpha].
In this situation the free quarks disappear, they become condensed in the hadrons.
Theory holds that for a brief time at the beginning of the universe there were no protons and neutrons, only free quarks and gluons.
The result was surprising, since theorists had expected the matter to behave like a gas of free quarks and gluons (a plasma).
Free quarks roamed a thick broth of gluons, particles that carry the strong force.
This soup of free quarks (particles that make up protons and neutrons) and gluons (particles that transmit the strong nuclear force) existed in nature for only a few millionths of a second after the Big Bang.
Some physicists still hope to find free quarks, although the usual theory says quarks cannot be free.
Litke specifically mentioned attempting to detect magnetic monopoles, free quarks, new kinds of heavy quarks and heavy stable particles.
Finally, a collaboration of the University of California at Berkeley and CERN will look for free quarks.
