Description
The perturbative series for finite-temperature field theories has very poor convergence properties and one needs a way to reorganize it. In this talk, I review
one way of reorganizing the perturbative series thermal QCD,
namely hard-thermal-loop perturbation theory (HTLpt).
I will present results for the pressure, trace anomaly, speed of sound and the quark susceptibilities from a 3-loop HTLpt calculation.
A careful comparison with available lattice data shows good agreement for a number of physical quantities.
