Transport theory of dissipative heavy-ion collisions

We have developed a transport theory on the basis of a one-body theory. This one-body transport theory starts out from a dynamical single-particle basis which incorporates main parts of the coupling in a coherent way. By deriving transport equations for one-body quantities it is possible to avoid the strong-coupling limit with its apparent drawback due to off-shell contributions. As the essential tool in this formulation we apply a suitable time-averaging which replaces the usual statistical assumptions in the derivation of (time-irreversible) transport equations. (orig./HSI)
