• Improved Gauss law model and in-medium heavy quarkonium at finite density and velocity 

      Lafferty, David; Rothkopf, Alexander Karl (Peer reviewed; Journal article, 2020-03)
      We explore the in-medium properties of heavy-quarkonium states at finite baryochemical potential and finite transverse momentum based on a modern complex-valued potential model. Our starting point is a novel, rigorous ...
    • Quarkonium phenomenology from a generalised Gauss law 

      Lafferty, David; Rothkopf, Alexander Karl (Peer reviewed; Journal article, 2019-05)
      We present an improved analytic parametrisation of the complex in-medium heavy quark potential derived rigorously from the generalised Gauss law. To this end we combine in a self-consistent manner a non-perturbative vacuum ...
