Outline of Final Research Achievements

With recent developments in study of high-density medium and QCD phase diagram with ultra-relativistic nuclear collisions, we performed theoretical studies towards understanding non-equilibrium aspects of QCD medium.
We evaluate quantitatively the effects of the gluon saturation in the incident nucleus on particle production in proton-nucleus collisions. Regarding time evolution, we formulate the equation of motion in tau-eta coordinates based on 2-particle irreducible effective action framework. As for statistical sampling of the systems with complex actions, we examine the pros and cons of two approaches, the complex Langevin equation and the Lefschetz thimble method, by applying them to simple models.
