Description
Bulk and shear viscosity coefficients of deconfined strongly interacting
matter are studied by means of an effective Boltzmann kinetic theory
assuming the quark-gluon plasma to be describable in terms of
quasiparticle excitations with medium-dependent dispersion relations.
At large temperatures, the results resemble parametric dependencies
on temperature and coupling known from perturbative QCD. This allows
for an extrapolation of the latter into the non-perturbative region finding
fairly nice agreement with available lattice QCD results. Correspondingly,
a small specific shear viscosity for energy densities reachable under
LHC conditions is predicted.
