Abstract：
Using the one-boson-exchange model, we studied the possible existence of very loosely bound hidden-charm molecular baryons composed of an anti-charmed meson and a charmed baryon. Our numerical results indicate that the Σ_cD^* and Σ_cD states exist, but that the Λ_cD and Λ_cD^* molecular states do not.
