Abstract

We propose stable exotic nuclei bound with D and B mesons with respect to heavy quark symmetry. We indicate that an approximate degeneracy of D(B) and D^*(B^*) mesons plays an important role, and discuss the stability of DN and BN bound states. We find the binding energies 1.4 MeV and 9.4 MeV for each state in the J^P=1/2^\ensuremath- with the I=0 channel. We discuss also possible existence of exotic nuclei DNN and BNN.
