Description
Two-point correlation functions of the quark bilinear field, known as meson susceptibility functions, are key physical quantities that provide insights into fluctuations in meson properties and the restoration of chiral and U(1) axial symmetries in the hot QCD system.
In this talk, I will present an analysis of these susceptibility functions at finite temperatures. Using effective model approaches, I will demonstrate their temperature dependence and compare the results with lattice QCD observations. Furthermore, the temperature dependence of the topological susceptibility, derived from the meson susceptibility functions, will be discussed. I will then examine the symmetries restoration on the meson susceptibility functions based on the effective model approaches. The effects of rotation on the hot QCD system will also be addressed.
