Query: QCD thermodynamics and confinement from a dynamical quasiparticle point
  of view   In this study it is demonstrated that a simple picture of the
  QCD gluon liquid emerges in the dynamical quasiparticle model that specifies
the active degrees of freedom in the time-like sector and yields a potential
energy density in the space-like sector. By using the time-like gluon density
(or scalar gluon density) as an independent degree of freedom - instead of the
temperature $T$ as a Lagrange parameter - variations of the potential energy
density lead to effective mean-fields for time-like gluons and an effective
gluon-gluon interaction strength at low density. The latter yields a simple
dynamical picture for the gluon fusion to color neutral glueballs when
approaching the phase boundary from a temperature higher than $T_c$ and paves
the way for an off-shell transport theoretical description of the parton
dynamics.
