Abstract
The perturbative series for finite-temperature field theories has very poorconvergence properties and one needs a way to reorganize it. In this talk, Ireview two ways of reorganizing the perturbative series for field theories atfinite temperature and chemical potential, namely hard-thermal-loopperturbation theory (HTLpt) and dimensional reduction (DR). I will presentresults for the pressure, trace anomaly, speed of sound and the quarksusceptibilities from a 3-loop HTLpt calculation and for the quarksusceptibilities using DR at four loops. A careful comparison with availablelattice data shows good agreement for a number of physical quantities.
