Modern heavy ion experiments reach collision energies that span the QCD phase diagram in the region of a partonic plasma state called the quark-gluon plasma (QGP). This relativistic QCD plasma is a strongly coupled hot/dense medium that lasts only a few fm/c. Being such a ephemeral state of matter, the only effective information about it is contained in the final particle shower collected by the experiment. Plethora of measurements show that the QGP behaves like a relativistic liquid with very small dissipative effects. Phenomenologically, a full theoretical framework of the QGP comprises of initial medium conditions, viscous hydrodynamics and particle shower (hadronization) phase. Each of these phases determines the predictive power of the model and puts a direct quantitative constrain on dissipative contributions when compared to data.
