Description
We study kinetic properties of a plasma consisting of gluons whose infrared dynamics is
improved by the Gribov-Zwanziger quantization. This approach includes essential
features of color confinement which set the plasma apart from conventional quasiparticle systems in several aspects. Our study focusses on a boost-invariant expansion for in and out of equilibrium configurations, which at late times can be characterized by the sound
velocity, cs, and the shear, eta, and bulk, zeta, viscosities. We obtain explicit expressions for the transport coefficients eta and zeta and check that they are consistent with the numerical solutions of the kinetic equation. At high temperature, we find a scaling zeta/eta ~ 1/3 cs^2 which manifests strong breaking of conformal symmetry in contrast to the case of weakly coupled plasmas.
