Dbar-N interaction from meson-exchange and quark-gluon dynamics

Understand

We investigate the Dbar-N interaction at low energies using a meson-exchange model supplemented with a short-distance contribution from one-gluon-exchange.

• The model is developed in close analogy to the meson-exchange KN interaction of the Juelich 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 short range part is assumed to receive additional contributions from genuine quark-gluon processes.
