Outline of Final Research Achievements

We have investigated dense QCD matter phase diagram by using theoretical frameworks including fluctuation effects. First, the QCD phase diagram in the strong coupling limit is studied by using the newly developed auxiliary field Monte-Carlo method. The obtained phase diagram is consistent with the one previously obtained in a different framework (the monomer-dimer-polymer simulations), thus the QCD phase diagram in the strong coupling limit is settled.Next, we have investigated the coupling effects of the quark number density (ρ) and the chiral condensate (σ) on the QCD phase diagram in the framework of the functional renormalization-group (FRG). The soft mode associated with the QCD critical point is a linear combination of ρ and σ, then the coupling of ρ and σ is found to enlarge the critical region. The baryon number distribution in heavy-ion collisions and the effect of isospin asymmetry on the phase diagram are also studied.
