Abstract

We discuss the possibility of existence of exotic nuclei containing charm and bottom mesons. We study the interaction between $\bar{D}$ (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 $\bar{D}$ (B) meson and nucleon N , and ﬁnd there are possible stable bound states with spin J^P = 1/2⁻ and isospin I = 0. We ﬁnd that the tensor interaction mixing $\bar{D}$ N and $\bar{D}$ *N (BN and B*N) plays an important role. We also qualitatively discuss the possible bound states of $\bar{D}$ (B) meson and two nucleons.
