We study the Polyakov loop correlator in the weak coupling expansion and show how the perturbative series re-exponentiates into singlet and adjoint contributions. We calculate the order $g^7$ correction to the Polyakov loop correlator in the short distance limit. We show how the singlet and adjoint free energies arising from the re-exponentiation formula of the Polyakov loop correlator are related to the gauge invariant singlet and octet free energies that can be defined in pNRQCD, namely we…

Heavy Quark-Antiquark Pairs at Zero and Finite Temperature with Effective Field Theories of QCD

We use effective field theories to study the interactions of heavy quarks in the vacuum and in medium. First, we show how boost transformations may be incorporated in a non-relativistic EFT through a

Modeling the nonperturbative contributions to the complex heavy-quark potential

In this paper, we construct a simple model for the complex heavy quark potential which is defined through the Fourier transform of the static gluon propagator. Besides the hard thermal loop resummed

Asymptotic behavior of the correlator for Polyakov loops.

It is shown that existing lattice calculations of the Polyakov loop correlator at the highest temperatures available do not probe the true asymptotic region.
