Research Abstract

Dynamics of the quark gluon plasma (QGP) created in high energy heavy ion collisions is described by developing an integrated dynamical model which unifies three models corresponding to three sequential stages of heavy ion reactions. The model enables us to simulate the reactions on an event-by-event basis and to analyze final particle distribution as done by experimental group. We also investigated novel phenomenon of the QGP dynamics such as Mach cone structure and found it important to interpret the recent observation of the jet structure at Large Hadron Collider.
