Abstract
We discuss the interaction of an open heavy meson ( and for charm or and for bottom) and a nucleon () by considering the , , , and exchange potentials. We construct a potential model by respecting chiral symmetry for light quarks and spin symmetry for heavy quarks. Model parameters are adjusted by referring the phenomenological nuclear (CD-Bonn) potentials reproducing the low-energy scatterings. We show that the resulting interaction may accommodate and bound states with quantum numbers , and . We find that, in the present potential model, the exchange potential plays an important role for the isosinglet channel, while the exchange potential does for the isotriplet one.
