Description
We study the static energy between a quark anti-quark pair in a thermal medium based on ensembles with $N_f=2+1$ dynamical HISQ flavors. Our dataset spans the phenomenologically relevant temperature range between T=140MeV-2GeV based on lattice sizes $48^3$x10,12 and 16. The real- and imaginary part of the potential is determined from the spectral function of Wilson-line correlators in Coulomb gauge. We assess the information content in the correlation functions and deploy three complementary strategies to reconstruct spectral information: model fits, Pade approximation and the Bayesian BR method. Limitations of each approach are carefully assessed.
