Exotic Nuclei with Charm and Bottom Flavors

We discuss the possible existence of exotic nuclei which contains charm and bottom flavors. We consider D and B mesons bound with nucleons. The interaction between D (B) meson and nucleon is supplied with the heavy quark symmetry. As a potential we use one pion exchange potential as long range force. We investigate possible DN (BN) bound state with several quantum numbers. We further discuss the possibility of the existence of DNN (BNN) as systems with baryon number two.
