The QCD phase transition from the deconfined partonic phase to the confined hadronic one, accompanied by the spontaneous breaking of chiral symmetry, is unique in the sense that we can experimentally test the paradigm above by reaching the other side of the transition by colliding two heavy nuclei at a sufficiently high energy. Experimental studies in the field has risen to a new stage since the phase …
