Gluon Condensate and Parton Propagation in a Quark-gluon Plasma
Finite temperature QCD can be used to describe properties of a quark-gluon plasma (QGP) possibly created in the fireball of relativistic heavy ion collisions and in the early Universe. There are two different methods available, namely lattice QCD and perturbation theory. Lattice QCD is a non-perturbative method, which can be used at all temperatures above and below the phase transition. However...
متن کاملEquilibration Rates in a Strongly Coupled Nonconformal Quark-Gluon Plasma.
We initiate the study of equilibration rates of strongly coupled quark-gluon plasmas in the absence of conformal symmetry. We primarily consider a supersymmetric mass deformation within N=2^{*} gauge theory and use holography to compute quasinormal modes of a variety of scalar operators, as well as the energy-momentum tensor. In each case, the lowest quasinormal frequency, which provides an app...
متن کاملTowards the Quark-Gluon Plasma
We discuss recent experimental results in the field of ultra-relativistic nuclear collisions. The emerging “picture” is a collectively expanding, initially hot and dense fireball in which strangenessand low-mass di-lepton pair production are enhanced and J/Ψ production is suppressed compared to expectations from nucleon-nucleon collisions. It is argued that, taken together, these data provide c...
متن کاملsignal the quark gluon plasma ?
We first review the production and the possible chemical equilibration of strange particles at CERN-SPS energies within a microscopic hadronic transport calculation. It is shown in particular that the strange quarks are produced initially via string excitations in the primary, secondary and ternary interactions. We then further elaborate on a recent idea of antihyperon production by multi-meson...
متن کاملThe 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...
