摘要：
We systematically investigate the possible molecular states composed of (1) two spin-3/2 doubly charmed baryons, and (2) a pair of spin-3/2 and spin-1/2 doubly charmed baryons. The one-boson-exchange (OBE) model is used to describe the potential between two baryons. The channel mixing effect is considered for the systems with the same quantum number (I (J(P))) but different total spin (S) and orbital angular momenta (L). We also study the channel mixing effect among the systems composed of various doubly charmed baryons if they have the same quantum number. Many of the systems are good candidates of molecular states.
