We propose a quasiparticle approach allowing to compute the equation of stateof a generic gauge theory with gauge group SU($N_c$) and quarks in an arbitraryrepresentation. Our formalism relies on the thermal quasiparticle masses(quarks and gluons) computed from Hard-Thermal-Loop techniques, in which thestandard two-loop running coupling constant is used. Our model is minimal inthe sense that we do not allow any extra ansatz concerning thetemperature-dependence of the running coupling. We first show that it is ableto reproduce the most recent equations of state computed on the lattice fortemperatures higher than 2 $T_c$. In this range of temperatures, an ideal gasframework is indeed expected to be relevant. Then we study the accuracy ofvarious inequivalent large-$N_c$ limits concerning the description of the QCDresults, as well as the equivalence between the QCD$_{AS}$ limit and the ${\calN}=1$ SUSY Yang-Mills theory. Finally, we estimate the dissociation temperatureof the $\Upsilon$-meson and comment on the estimations' stability regarding thedifferent considered large-$N_c$ limits.
