Abstract: (Elsevier)

The shear viscosity coefficient of the quark-gluon plasma is calculated by considering the relaxation time approximation. Screening effects are taken into account by using an effective perturbation theory developed recently for the finite temperature QCD in the weak coupling limit. The result agrees with the one obtained from a variational approach to the Boltzmann equation, but is at variance to other results based on a Kubo-type formula.
