Strongly interacting QGP at finite baryon density in the self-consistent T-matrix approach*

We generalize the self-consistent thermodynamic T-matrix approach to investigate the strongly interacting quark-gluon plasma at finite baryon density. Our model employs a Hamiltonian formulation with a separable 2-body interaction in a Φ-derivable quantum many-body theory. It is calibrated to describe available lattice-QCD results for thermodynamic quantities at μ_B = 0. The calculations account for the off-shell dynamics of the interacting medium and feature broad non-quasiparticle parton spectral functions as well as emerging hadronic resonance states. This, in particular, leads to a transition of the dominant degrees of freedom from hadronic resonances, encoded by the Luttinger-Ward functional of the model, to partons as the energy density of the medium increases.
