Quark-Gluon Plasma (QGP) is a nation of topic expected by way of the idea of robust interactions - Quantum Chromodynamics (QCD). the realm of QGP lies on the interface of particle physics, box concept, nuclear physics and many-body conception, statistical physics, cosmology and astrophysics. In its short heritage (about a decade), QGP has obvious a quick convergence of rules from those formerly diverging disciplines.
