Abstract

We study correlation functions of various static meson operators of size r at non-zero temperature in 2+1 flavor QCD, including Coulomb gauge fixed operators and Wilson loops with smeared spatial parts. The numerical calculations are performed on 24³ × 6 lattices using highly improved staggered quark action. We discuss possible implications of our findings on the temperature dependence of the static energy of pair.
