Exotic nuclei with charm and bottom flavor

Abstract

We discuss the possibility of existence of exotic nuclei containing charm and bottom mesons. We study the interaction between $ar{D}$ (B) mesons and nucleons from view of heavy quark symmetry, and derive the one pion exchange potentials. We apply these potentials to the two body system of $ar{D}$ (B) meson and nucleon N , and find there are possible stable bound states with spin JP = 1/2− and isospin I = 0. We find that the tensor interaction mixing $ar{D}$N and $ar{D}$*N (BN and B*N) plays an important role. We also qualitatively discuss the possible bound states of $ar{D}$ (B) meson and two nucleons.
