报告简介

　　Thus far, the hot QCD properties have been explored by both lattice simulations and effective model analyses to gain a deeper understanding of QCD nonperturbative nature. However, when including quark chemical potential, lattice QCD simulations suffer from the sign problem and cannot work in baryonic matter. For this reason, our understanding of QCD in high-density matter remains limited compared to that in hot medium.

　　Instead of real QCD with chemical potential, the sign problem can be avoided in the two-color QCD with two flavors. Recently, the two-color lattice QCD simulations have provided several observations such as the topological susceptibility and the sound velocity in the baryonic matter. However, in this context the effective model analysis remains underdeveloped.

In this talk I will employ the effective model to compare with the lattice observations. Through the comparison, I will try to gain a understanding of the baryonic QCD matter.
