It is known that the quark-gluon plasma is well described in terms of perfect fluid dynamics [1]. Besides, it is a common fact that there is nothing perfect in the world (although one should try - LT :-) ).

Therefore, one needs to include dissipative processes, which are described by transport coefficients, into the QGP dynamics. I will present the shear viscosity obtained from the relaxation time approximation of the Boltzmann equation. The calculations are performed within the quasiparticle model, where dynamical quark and gluon masses depend on the lattice data [2].
