A model is developed for the hadronic interaction in the two-nucleon system above pion threshold which is based on meson, nucleon and β degrees of freedom and which includes full meson retardation in the exchange operators. For technical reasons, the model allows maximal one meson to be present expl

The modification of the Ο-meson self-energy due to the coupling to in-medium pions is calculated consistently at finite baryon density and temperature, keeping the full 3-momentum dependence in a gauge invariant way. As a function of nucleon density, the Ο-meson spectral function is strongly enhance
Photodisintegration of the deuteron above Ο threshold is studied in a coupled-channel approach including Nβ and Οd channels with consideration of pion retardation in potentials and exchange currents. A much improved description of total and differential cross sections in the energy region between Ο
