Abstract: A recently proposed covariant formulation of the relativistic Landau theory of quasi-particles is further developed and applied to the quark-gluon plasma. A closed transport equation for the singlet quark distribution function is established by following a reasoning akin to the one due to Klimontovich. Assuming that the dissipative effects are dominated by soft quark-quark encounters, we obtain a quasi-particle collision term resembling the Balescu-Guernsey-Lenard integral. The scattering amplitude is shown to involve the exchange of at least two gluons. The lowest order forward scattering amplitude is evaluated explicitly. It turns out to be of order α32s on account of the plasmon effect.
