Comment on and Erratum to "Pressure of Hot QCD at Large Nf"
Andreas Ipp, Guy D. Moore, Anton Rebhan
Abstract
We repeat and correct the recent calculation of the thermodynamic potential of hot QCD in the limit of large number Nf of fermions. The new result for the thermal pressure turns out to agree significantly better with results obtained from perturbation theory at small coupling. For large coupling, a nonmonotonic behaviour is reproduced, but the pressure of the strongly coupled theory does not exceed the free pressure as long as the Landau pole ambiguity remains negligible numerically.
