“…The first lattice studies [4][5][6] have supported this idea, and it was soon realized that high-energy ion collisions can be used to create QGP, see [7] for a recent review and references.…”

Nonperturbative effects in the quark-gluon thermodynamics are studied in the framework of Vacuum Correlator Method. It is shown, that two correlators: colorelectric D E 1 (x) and colormagnetic D H (x), provide the Polyakov line and the colormagnetic confinement in the spatial planes respectively. As a result both effects produce the realistic behavior of P (T ) and s(T ), being in good agreement with numerical lattice data. * lukashov@phystech.edu † simonov@itep.ru

“…Equation (6) is written in the color-singlet channel for static quarks, but in the calculations of the EoS reported in the next section we include all possible two-body color channels with appropriate Casimir factors and relativistic corrections [19]. The screening of the string term is constrained using [20] and also contains a quadratic term, (c b m s r) 2 , to better mimic string breaking effects. The genuine two-body part is defined as V(r) = V C (r) + V S (r), while the nonzero infinite-distance limit,Ṽ(∞), is related with the mass generated by self-interactions,…”

“…The QCD phase structure is believed to be tightly connected to two key phenomena of the standard model, namely hadronic mass generation and color confinement. In addition, it turned out that the strongly interacting fireball medium formed in ultra relativistic collisions of heavy nuclei possesses the smallest known ratio of viscosity to entropy density, giving rise to the notion of the strongly coupled quark-gluon plasma (sQGP) [1][2][3], a near-perfect liquid. The microscopic structure of the sQGP, including its prevalent degrees of freedom and its possible relation to the nearby phase transition(s) into hadronic matter, remains a forefront topic in contemporary research.…”

Abstract. We discuss a non-perturbative T -matrix approach to investigate the microscopic structure of the quark-gluon plasma (QGP). Utilizing an effective Hamiltonian which includes both light-and heavy-parton degrees of freedoms. The basic two-body interaction includes color-Coulomb and confining contributions in all available color channels, and is constrained by lattice-QCD data for the heavy-quark free energy. The in-medium T -matrices and parton spectral functions are computed selfconsistently with full account of off-shell properties encoded in large scattering widths. We apply the Tmatrices to calculate the equation of state (EoS) for the QGP, including a ladder resummation of the Luttinger-Ward functional using a matrix-log technique to account for the dynamical formation of bound states. It turns out that the latter become the dominant degrees of freedom in the EoS at low QGP temperatures indicating a transition from parton to hadron degrees of freedom. The calculated spectral properties of one-and two-body states confirm this picture, where large parton scattering rates dissolve the parton quasiparticle structures while broad resonances start to form as the pseudocritical temperature is approached from above. Further calculations of transport coefficients reveal a small viscosity and heavy-quark diffusion coefficient.

“…For a numerical estimate, let us use the baryon chemical potential µ ≃ 80 MeV as extracted from hadron abundances in AuAu collisions at √ s = 62 GeV [32]. Since the polarization of Λ hyperons results mostly from the polarization of strange quarks, we have to use the chemical potential of strange quarks that is µ s ≃ µ/3.…”

The susceptibility of finite-density QCD matter to vorticity is introduced, as an analog of magnetic susceptibility. It describes the spin polarization of quarks and antiquarks in finite-density QCD matter induced by rotation. We estimate this quantity in the chirally broken phase using the mixed gauge-gravity anomaly at finite baryon density. It is proposed that the vortical susceptibility of QCD matter is responsible for the polarization of Λ andΛ hyperons observed recently in heavy ion collisions at RHIC by the STAR collaboration.
