The Quark-Gluon-Plasma Liquid
The quark-gluon plasma close to the critical temperature is a strongly interacting system. Using strongly coupled, classical, non-relativistic plasmas as an analogy, we argue that the quark-gluon plasma is in the liquid phase. This allows to understand experimental observations in ultrarelativistic heavy-ion collisions and to interpret lattice QCD results. It also supports the indications of th...
متن کاملNonperturbative heavy-quark diffusion in the quark-gluon plasma.
We evaluate heavy-quark (HQ) transport properties in a quark-gluon plasma (QGP) within a Brueckner many-body scheme employing interaction potentials extracted from thermal lattice QCD. The in-medium T matrices for elastic charm- and bottom-quark scattering off light quarks in the QGP are dominated by attractive meson and diquark channels which support resonance states up to temperatures of ~1.5...
متن کاملNonperturbative Equation of State of Quark-gluon Plasma
The paper is devoted to the systematic derivation of nonperturba-tive thermodynamics of quark-gluon plasma, on the basis of the background perturbation theory. Vacuum background fields enter only in the form of field correlators, which are known from lattice and analytic calculations. In the lowest order in α s the purely nonperturbative sQGP thermodynamics is expressed through single quark and...
متن کامل95 Hot Nonperturbative Qcd ∗
Starting from the new background field formalism for T > 0, with nonperturbative (NP) background given as gauge invariant fiel corre-lators, new perturbation theory and diagram technic is introduced. Confined and deconfined phases are explicitly described and critical temperature T c is expressed in terms of the scale anomaly term. Resulting numerical estimates of T c agree well with lattice da...
متن کاملPhotons from Quark Gluon Plasma and Hot Hadronic Matter
The productions of real photons from quark gluon plasma and hot hadronic matter formed after the nucleus nucleus collisions at ultra-relativistic energies are discussed. The effects of the spectral shift of the hadrons at finite temperature on the production of photons are investigated. On the basis of the present analysis it is shown that the photon spectra measured by WA98 collaboration in Pb...
