Improved Resummations for the Thermodynamics of the Quark-Gluon Plasma

Abstract

Two recent attempts for overcoming the poor convergence of the perturbation expansion of the thermodynamic potentials of QCD are discussed: an HTL-adaption of ``screened perturbation theory'' and approximately self-consistent HTL resummations in the two-loop entropy.
