Description

We discuss the interaction between an anti-$D$ meson and a nucleon in terms of the meson exchange model. We provide the interaction vertices and the non-relativistic potentials, based on the chiral symmetry and the heavy quark spin symmetry. In numerical calculations, we show several bound states below the lowest thresholds, which contain at least five quarks as the pentaquark states. We compare our results with the experimental data reported by ALICE in LHC. We apply a similar discussion to the bottom sector.
