Haidenbauer, G. Krein, U. Meißner, L. Tolos] Abstract.: A model of the DN interaction is presented which is developed in close analogy to the meson-exchange $ \bar{{K}}$ N potential of the Jülich group utilizing SU(4) symmetry constraints. The main ingredients of the interaction are provided by vector meson ($ \rho$ , $ \omega$ exchange and higher-order box diagrams involving D * N , D $ \Delta$ , and D * $ \Delta$ intermediate states. The coupling of DN to the $ \pi$ $ \Lambda_{c}^{}$ and $ \pi$ $ \Sigma_{c}^{}$ channels is taken into account. The interaction model generates the $ \Lambda_{c}^{}$(2595) -resonance dynamically as a DN quasi-bound state. Results for DN total and differential cross sections are presented and compared with predictions of two interaction models that are based on the leading-order Weinberg-Tomozawa term. Some features of the $ \Lambda_{c}^{}$(2595) -resonance are discussed and the role of the near-by $ \pi$ $ \Sigma_{c}^{}$ threshold is emphasized. Selected predictions of the orginal $ \bar{{K}}$ N model are reported too. Specifically, it is pointed out that the model generates two poles in the partial wave corresponding to the $ \Lambda$(1405) -resonance. The Author(s), 2011 Haidenbauer J.
