Abstract We calculate the colour averaged and colour singlet free energies of static quark–antiquark sources placed in a thermal gluonic heat bath. We discuss the renormalization of these free energies using the short distance properties of the zero temperature heavy quark potential. This leads to the definition of the renormalized Polyakov loop as an order parameter for the deconfinement phase transition of the SU(3) gauge theory which is well behaved in the continuum limit.

The QCD transition temperature: Results with physical masses in the continuum limit (2006, methodology): “ quark-antiquark pair. The absolute value of the Polyakov-loop vanishes in the continuum limit. It needs renormalization. This can be done by renormalizing the free energy of the quark-antiquark pair [20]. Note, that QCD at T6=0 has only the ultraviolet divergencies which are already present at T=0.”
