DN interaction from the Juelich meson-exchange model

The $DN$ interaction is studied in close analogy to the meson-exchange $\bar KN$ potential of the Juelich group using SU(4) symmetry constraints. The model generates the $Λ_c$(2595) resonance dynamically as a $DN$ quasi-bound state. Results for $DN$ scattering lengths and cross sections are presented and compared with predictions based on the Weinberg-Tomozawa term. Some features of the $Λ_c$(2595) resonance are also discussed emphasizing the role of the near-by $πΣ_c$ threshold.
