We compute the correlation functions of Polyakov loops in $SU(N_c)$ gauge theories by explicitly summing all diagrams at tree level in two special cases, for $N_c = 2$ and $N_c = \infty$. When $N_c =2$ we find the expected we find Coulomb-like behavior at short distances, $\sim 1/x$ as the distance $x \rightarrow 0$. In the planar limit at $N_c = \infty$ we find a weaker singularity, $\sim 1/\sqrt{x}$ as $x \rightarrow 0$. In each case, at short distances the behavior of the correlation…

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 $g^7$

### 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
