Abstract: The order parameter for the pure Yang-Mills phase transition is the Polyakov loop which encodes the symmetries of the ${Z}_{N}$ center of the $\mathrm{SU}(N)$ gauge group. On the other side the physical degrees of freedom of any asymptotically free gauge theory are hadronic states. Using the Yang-Mills trace anomaly and the exact ${Z}_{N}$ symmetry we construct a model able to communicate to the hadrons the information carried by the order parameter.
