Description
The weak-coupling expansion for the pressure of hot field theories is known to fluctuate wildly and have poor convergence properties. In this talk, I will discuss the reorganization of the perturbative series of the thermodynamics quantities using hard-thermal-loop perturbation theory. This is a gauge-invariant approach that shows improved convergence properties. I will compare preliminary results for the QCD pressure with lattice data.
