[en] Understanding the QCD phase transition is nowadays a fascinating topic since RHIC and LHC have
pointed out some evidences of the existence of a new state: the Quark-Gluon Plasma (QGP), a state
of matter in which quarks and gluons could move freely.
Up to now, the best theoretical approach to characterize QCD at finite temperature is lattice QCD.
Nevertheless, phenomenological approaches are also of great interests: They can provide us a
picture of the physical mechanisms underlying the QCD phase transition.
In this seminar, we will try to understand the pure-glue phase transtion thanks to quasiparticle
approaches. Under the critical temperature (Tc) of deconfinement, a Hadron Resonance Gas model
(HGR) will be used. Well above Tc, we will characterize the QGP equations of state with an ideal
gas framework. Between these two regions, a project of including 2-gluon interactions thanks to the
T-matrix formalism is in progress.
