Stabilizing Perturbative Yang-Mills Free Energy with Gribov Quantization

Nan Su (University Bielefeld)

We evaluate the free energy of Yang-Mills theory using the Gribov quantization that copes with nonperturbative resummation. The magnetic scale is systematically incorporated in the framework. The calculation is done in a renormalization-scale-free way, and the only uncertainty comes from the nonperturbative running coupling that is adopted from the lattice measurement. The result is impressively robust down to T~2Tc and in extremely good agreement with the lattice data.
