Outline of Final Research Achievements

In this study, we investigated correlation, fluctuation, and transportation in the system created in high energy nucleus collisions. The fundamental theory of the strong interaction is quantum chromodynamics. In high energy nucleus collisions, the quark-gluon plasma, where quarks and gluons are deconfined, is created. In this study, we focused on the charmonium correlation in the quark-gluon plasma and the transportation of fluctuations of conserved charges, and obtains new insights.
