摘要：

Lambda N-c bound state problem is investigated in the one-meson-exchange potential model. The potentials are obtained from an effective Lagrangian reflecting the heavy quark symmetry, chiral symmetry, and hidden local symmetry. We also consider the contributions from the coupled channels of Sigma N-c and Sigma*N-c. It is found that the channel coupling is very important in binding the baryons. We find that the formation of the nearly degenerate J(P) = 0(+) and J(P) = 1+Lambda N-c molecular bound states is plausible, although the results are sensitive to the cutoff parameters,.
