| Outline of Final Research Achievements |
High-energy nuclear collision experiments have been performed toward understanding of deconfined nuclear matter "quark gluon plasma (QGP)" which existed 10 micro seconds after the Big Bang. Because the reaction of high-energy nuclear collisions undergoes highly complicated processes, it is anticipated to model each stage of reactions through a proper picture and to unify them as a dynamical model.
In this reseach, we describe the space-time evolution of high-energy nuclear collisions using a unified dynamical model based on hydrodynamic picture of the QGP. We first revailed the role of hydrodynamic fluctuations in observables. We next developed a new class of dynamical model based on the core-corona picture which contains equilibrated and non-equilibrated components. Using this new model, we quantified the fraction of the QGP fluids for each collision system and found it is smoothly changing as increasing the number of produced hadrons regardless of collision system nor energy.
