T-matrix Analysis of Static Wilson Line Correlators from Lattice QCD at Finite Temperature

We utilize a previously constructed thermodynamic T-matrix approach to the quark-gluon plasma (QGP) to calculate Wilson line correlators (WLCs) of a static quark antiquark pair and apply them to the results from realistic 2+1-flavor lattice-QCD (lQCD) computations. The pertinent T-matrix results can describe the lQCD data for WLCs fairly well, but refinements of the input parameters are necessary to improve the agreement, providing new insights. This renders the T-matrix a more accurate and reliable tool to make predictions for the spectral and transport properties of the QGP, i.e., the charm-quark spatial diffusion coefficients turn out to be in agreement with lQCD results.
