abstract

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 2+1-flavor lattice-QCD (lQCD) computations with realistic pion mass. The self-consistent $T$-matrix results, which include constraints from the lQCD equation of state in the light-parton sector, can describe the lQCD data for WLCs fairly well once refinements of the input parameters are implemented. In particular, the input potential requires less screening than used in previous $T$-matrix analyses. Pertinent predictions for the spectral and transport properties of the QGP are discussed, including the spatial diffusion coefficient for heavy quarks which turns out to have a rather weak temperature dependence, in approximate agreement with recent lQCD results.

Discussion (0). Continue with ORCID to comment.

  1. Coupled charm and charmonium transport in a strongly coupled quark-gluon plasma

    nucl-th 2026-03 conditional novelty 7.0 of 10

    A unified T-matrix transport framework for charm-quark diffusion and charmonium kinetics with off-shell spectral functions recovers the statistical equilibrium limit and gives fair LHC charmonium R_AA data.

  2. In-medium bottomonium properties from lattice NRQCD calculations with extended meson operators

    hep-lat 2025-01 conditional novelty 6.0 of 10

    Bottomonium masses do not shift in the quark-gluon plasma up to 250 MeV, but thermal widths are nonzero and highly sensitive to the assumed spectral function shape.
