Abstract

We examine the chiral phase transition of strong interaction within a linear sigma-model with two light quark flavors. Going beyond previous mean field analyses of the phase diagram, we derive an analytic renormalization group flow equation for the thermodynamic potential including mesonic fluctuations.
