Research Abstract

In this study, non-equilibrium phenomena of the quark gluon plasma (QGP) in relativistic heavy ion collisions, which involve various and complicated processes, are investigated toward development of a dynamical model and understanding of transport properties of the QGP. In particular, (1)effects of fluctuation of produced matter in the initial stage on the dynamics, (2)relativistic viscous hydrodynamics of the QGP, and (3)effects of dissipation of hadrons on final observables are studied in detail.
