Abstract

We compute the pressure and entropy of hot QCD in the limit of large number of fermions, Nf >> Nc ~ 1, to next to leading order in Nf. At this order the calculation can be done exactly, up to ambiguities due to the presence of a Landau pole in the theory; the ambiguities are O(T8/Λ4Landau) and remain negligible long after the perturbative series (in g2 Nf) has broken down. Our results can be used to test several proposed resummation schemes for the pressure of full QCD.
