I studied properties of the quark-gluon plasma, which is thought to have existed in the early universe, by lattice gauge calculation, which is a first principle calculation of quantum chromodynamics, the fundamental theory of the strong force.The experimental method to create the quark-gluon plasma is high energy heavy ion collisions. The measurement of the second and higher order fluctuations of the electric charge, which is a conserved quantity, is one of diagostic tools to understand what kind of system was created in those collisions. I studied the time evolution of the second and higher order fluctuations of the electric charge and the finite volume effect on them.
