Following Gluonic World Lines to Find the QCD Coupling in the Infrared — •Dmitri Antonov and Hans-Juergen Pirner — Institut für Theoretische Physik, Universität Heidelberg, Philosophenweg 19, 69120 Heidelberg

We calculate the polarization operator of a valence gluon propagating in the confining background using a parametrization of the Wilson loop with the minimal-area law. This enables us to obtain the infrared freezing of the running strong coupling in the confined and deconfined phases.
