Query: Test particle description of transport processes for states with a
  continuous mass spectrum   Aiming at a description of transport processes where the dynamically
generated width of the states is potentially large a transport equation beyond
the quasiparticle approximation is derived in first order gradient expansion.
An effective particle number is identified which is exactly conserved by the
coarse grained transport equation. Using a test particle ansatz for this
conserved quantity allows to rewrite the transport equation into equations of
motion for test particles. The two-body collision terms are formulated in terms
of the test particles which gain non-trivial renormalization factors due to the
coarse graining process.
