QCD matter

Quark matter refers to any of a number of phases of matter built out of quarks and gluons. These constituents of quark matter carry colour charges and interact through Quantum chromodynamics. The scale of this theory, ΛQCD is of the order of a few hundred MeV (ie, about 10^{12} K). In this article low temperature (or chemical potential) will mean energies lower than this.

Hot quark matter called the quark-gluon plasma is expected to have filled the universe till about 20 or 30 microseconds after the big bang. Some colder phases such as strange matter and colour superconductors have been conjectured as present day constituents of stars denser even than neutron stars. The normal phase of quark matter is what we see everywhere else. In this phase quarks are confined within hadrons, either by partnering with an anti-quark to make a meson, or by joining with two other quarks to build a baryon.

Gluon: In particle physics, gluons mediate strong interactions of quarks in quantum chromodynamics. The first direct experimental evidence of gluons was found in 1979 when three jet events were observed at the electron-positron collider called PETRA at DESY in Hamburg.
