摘要：

A model of the DN interaction is presented which is developed in close analogy to the meson-exchange (K) over barN potential of the Julich 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 (K) over barN 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.
