Query: All orders Boltzmann collision term from the multiple scattering
  expansion of the self-energy   Starting from the Kadanoff-Baym relativistic transport equation and the
multiple scattering expansion of the self-energy, we obtain the Boltzmann
collision terms for any number of participating particles to all orders in
perturbation theory within a quasi-particle approximation. This work completes
a program initiated by Carrington and Mrowczynski and developed further by
present authors and Weinstock in recent literature.
