| dc.description | The extrapolation of truncated perturbative series to the large coupling regime is not reliable since the accuracy of the calculations cannot be improved systematically by a finite set of higher order terms. Instead, a nonperturbative approach is proposed here to describe the thermodynamics of strongly coupled plasmas. Within the $ϕ^4$ theory, it is derived from the Luttinger-Ward theorem and amounts to a quasiparticle description. The approach is extended to the quark-gluon plasma. Even close to the confinement temperature it is found to be in a good agreement with lattice data of several gauge systems. The model is applied to predict the equation of state of the quark-gluon plasma with realistic quark masses. | |
