Sommaire:

I will present the result of a calculation of the thermodynamic functions of a quark-gluon plasma for general Nc and Nf to three-loop order using hard-thermal-loop perturbation theory. At this order, all ultraviolet divergences can be absorbed into renormalizations of the vacuum energy, the HTL mass parameters, and the strong coupling constant. I will show that at three loops, the results for the pressure, energy density, entropy density, and the trace anomaly are in very good agreement with lattice data down to temperatures T ~ 2Tc.
