A Review of Functional Renormalization Group approach to the current quark mass dependence of criticality within the Two-Flavor Quark-Meson Model

Increasing the number of hadrons into a finite size nuclei, so as to remove the physical vacuum, causes a singularity to occur, the phenomenon is used to be explain with QCD phase diagram which is a function of temperature, $T$, and chemical baryon potential, \begin{figure}[htbp] \centerline{\includegraphics[width=0.18in,height=0.20in]{081220201.eps}} \label{fig1} \end{figure} . In this submission, the authors will give a review on the present state of understanding of properties of phase transition region and behavior exhibited during phase transition process from hadronic matter to quark-gluon plasma by the functional renormalization group (FRG) approach to reveal useful information about the criticality in QCD. Our research work is mainly to use FRG within the two-flavor quark meson model to reveal information about criticality in QCD..
