Outline of Final Research Achievements

The relativistic heavy-ion collisions are important experimental tool to investigate the new state of matter called the quark-gluon plasma on the earth. In the present research, I extensively studied non-Gaussian fluctuations of conserved charges which acquire much attention recently in this field as important experimental observables which enable us to investigate properties of the hot medium in early stage created by the heavy-ion collisions. In particular, we studied rapidity window dependences as experimental tools to understand early-stage thermodynamics, finite volume effects and efficiency problem in fluctuation observables in experiments for the first time. These results received much attention over the world and I accepted invitations to international conferences more than 10 times during this period.
