    "abstract": "We adopt a truncated version of two-body dynamics by neglecting three-body\ncorrelations, as is supported by microscopic numerical calculations.\nIntroducing orthogonal channel correlations for the pp- and the ph-channel and\nintegrating the latter in terms of vibrational RPA-states we derive a retarded\ntwo-body equation. Its solution is nonperturbative with respect to loops,\nladders and mixed contributions. In the stationary limit we obtain an equation\nfor a generalised effective interaction which iterates both the G-matrix and\nthe polarisation matrix. An in-medium scattering approach transparently\ndemonstrates the collisional damping of the vibrations.",
