Transport properties of the quark-gluon plasma from lattice QCD
I review the progress made in extracting transport properties of the quark-gluon plasma from lattice QCD simulations. The information on shear and bulk viscosity, the “low-energy constants” of hydrodynamics, is encoded in the retarded correlators of Tμν, the energy-momentum tensor. Euclidean correlators, computable on the lattice, are related to the retarded correlators by an integral transform...
متن کاملTransport Properties of Quark and Gluon Plasmas
The kinetic properties of relativistic quark-gluon and electron-photon plasmas are described in the weak coupling limit. The troublesome Rutherford divergence at small scattering angles is screened by Debye screening for the longitudinal or electric part of the interactions. The transverse or magnetic part of the interactions is effectively screened by Landau damping of the virtual photons and ...
متن کاملHadronic modes and quark properties in the quark-gluon plasma
Based on interaction potentials between a heavy quark and antiquark as extracted from recent QCD lattice calculations, we set up a Brueckner-type many-body scheme to study the properties of light (anti-) quarks in a quark-gluon plasma at moderate temperatures, T 1–2 Tc. The quark-antiquark T matrix, including both color-singlet and color-octet channels, and corresponding quark self-energies and...
متن کاملMagnetic properties of holographic multiquarks in the quark-gluon plasma
We study the magnetic properties of the coloured multiquark states in the quarkgluon plasma where the gluons are deconfined and the chiral symmetry is still broken, using the Sakai-Sugimoto model. External magnetic field induces a first order phase transition for certain multiquark states where the magnetization abruptly turns into negative values at large field. Magnetic field also makes it mo...
متن کاملSpectral Properties of Quarks in the Quark-Gluon Plasma
We analyze the spectral properties of the quark propagator above the critical temperature for the deconfinement phase transition in quenched lattice QCD using clover improved Wilson fermions. The bare quark mass dependence of the quark spectral function is analyzed by varying the hopping parameter κ in Landau gauge. We assume a two-pole structure for the quark spectral function, which is numeri...
