Static meson correlators in 2+1 flavor QCD at non-zero temperature

Understand

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 24^3x6 lattices using highly improved staggered quark action.
• We discuss possible implications of our findings on the temperature dependence of the static energy of QQbar pair.
