Abstract

We report on the status of the analysis of the static energy in 2 + 1 + 1-flavor QCD. The static energy is obtained by measuring Wilson line correlators in Coulomb gauge using the HISQ action, yielding the scales r₀/a, r₁/a, r₂/a, their ratios, and the string tension σri². We put emphasis on the possible effects due to the dynamical charm-quark by comparing the lattice results to continuum results of the static energy with and without a massive flavor at two-loop accuracy. We employ gauge-field ensembles from the HotQCD and MILC Collaborations.
