摘要：Possible existence of bound states of a charmed baryon, Λ_c, Σ_c, Σ*_cwith a nucleon, N, as well as two charmed baryons, Λ_cΛ_c, etc., are examined in the meson exchange potential approach. The heavy quark spin symmetry induces a strong tensor coupling between Λ_cN, Σ_cN and Σ*_cN states, which causes a bound state of Λ_cN (J = 0~+and 1~+) states. Such a bound state is also seen in the spin-singlet Λ_cΛ_cchannel, which resembles the H dibaryon in the strange sector.
