Perturbative study of NLO chromoelectric correlators in Euclidean space

Abstract

We report on the perturbative study, at next-to-leading order (NLO), of correlation functions at finite temperature of two chromoelectric fields connected by an adjoint Wilson line in Euclidean space. We find a source of asymmetry in two of the correlators studied. Finally, we compare the results with recent Lattice QCD calculations at high temperatures and show a good agreement between the two.
