Query: Benchmarking the Bayesian reconstruction of the non-perturbative heavy
  $Q\bar{Q}$ potential   The extraction of the finite temperature heavy quark potential from lattice
QCD relies on a spectral analysis of the real-time Wilson loop. Through its
position and shape, the lowest lying spectral peak encodes the real and
imaginary part of this complex potential. We benchmark this extraction strategy
using leading order hard-thermal loop (HTL) calculations. I.e. we analytically
calculate the Wilson loop and determine the corresponding spectrum. By fitting
its lowest lying peak we obtain the real- and imaginary part and confirm that
the knowledge of the lowest peak alone is sufficient for obtaining the
potential. We deploy a novel Bayesian approach to the reconstruction of
spectral functions to HTL correlators in Euclidean time and observe how well
the known spectral function and values for the real and imaginary part are
reproduced. Finally we apply the method to quenched lattice QCD data and
perform an improved estimate of both real and imaginary part of the
non-perturbative heavy $Q\bar{Q}$ potential.
