Query: Color screening in $2+1$ flavor QCD at large distances   We study correlation functions of spatially separated static quark-antiquark
pairs in $2+1$ flavor QCD in order to investigate the nature of color screening
at high temperatures. We perform lattice calculations in a wide temperature
range, $116~\text{MeV} \leq T \leq 5814~\text{MeV}$, using the highly improved
staggered quark (HISQ) action and several lattice spacings to control
discretization effects. We alleviate the UV noise problem through the use of
four dimensional hypercubic (HYP) smearing, which enables the reconstruction of
correlators and determination of screening properties even at low temperatures
and at large distances.
