Résumé :
My presentation is 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 this problem. I will mainly concentrate on our recent two works where 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.The other work is related to the effect of mixing between quarkonia and tetraquark onthe QCD phase diagram using an effective chiral quark-diquark model.
