Abstract

We discuss the possibility of existence of exotic nuclei containing charm and bottom mesons. We study the interaction between (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 (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 N and *N (BN and B*N) plays an important role. We also qualitatively discuss the possible bound states of (B) meson and two nucleons.
