摘　　要：In this work,we study the doubly charmed dibaryon states with the qqqqcc(q=u,d,s)configuration.The mass spectra of doubly charmed dibaryon states are obtained systematically within the chromomagnetic interaction model.In addition to the mass spectrum analysis,we illustrate their two-body strong decay behaviours.Our results suggest that there may be narrow states or even stable states that cannot decay through the strong interaction.We hope that our results will provide valuable information for further experimental searches for doubly charmed dibaryon states.
