Scalar Meson and its effect on QCD Phase transition

Description
My presentation will be about light meson and their effect on QCD phase diagram. In the first part of my talk I will briefly review the problem of scalar meson below 2 GeV along with the current understanding of QCD Phase diagram. In the second half I will talk about our relevant works on these problems. For the scalar meson problem, we build an extended linear sigma model consisting of quarkonia tetraquark and glueball fields to study the nature and compostion of the scalar meson below 2 GeV. For QCD phase transition part I will summarize ours result from effective model study.
