In the high-energy nuclear physics we probe that nuclear matter is on the level of its fundamental constituents such as quarks and gluons. The phase transition between de confined quark-gluon matter, normal quark-gluon matter and normal nuclear matter is called as Quark Gluon Plasma. In the very high energy collisions of heavy nuclei quarks and gluons are released from the hadronic bounds of matter and therefore the new state of matter is formed which is also called as Quark-gluon plasma. The transition from the hadronic matter where neutrons, protons and other hadrons are individual particles to the quark-gluon plasma phase which is a definite prediction to the theory of strong interactions. Generally the high energy collisions of heavy nuclei that is plasma which lives only for 10-22 sec because it gets back to the hadronic phase when its rapid expansion is cooled down.
