Realistic in-medium heavy-quark potential from high statistics lattice QCD simulations

P Petreczky, A Rothkopf, J Weber - Nuclear Physics A, 2019 - Elsevier
We present our first results on a direct computation of the complex in-medium heavy quark
potential from realistic lattice QCD simulations. Ensembles with N τ= 12 from the HotQCD
and TUMQCD collaboration offer unprecedented high statistics, those with N τ= 16
unprecedented time resolution, making possible a robust extraction of the real part from the
spectral functions of Wilson line correlators. To this end we deploy a combination of a
Bayesian reconstruction (BR method), as well as a Padé-like approximation. We corroborate …
