Abstract: We perform a systematical investigation of the singly charmed dibaryon system with strangeness numbers S = − 1 , − 3 , and − 5 in the framework of the chiral quark model. Two resonance states with strangeness numbers S = − 1 are obtained in the baryon-baryon scattering process. In the Λ Λ c and N Ξ c * scattering phase shifts, the Σ Σ c appears as a resonance state with the mass and width 3591–3614 MeV and 11.75 MeV, respectively. In the N Ξ c and N Ξ c ′ scattering phase shifts, the Σ Σ c * exhibits as a resonance state with the mass and width 3621–3624 MeV and 14.9 MeV, respectively. All these heavy-flavor dibaryons are worth searching for in experiments. Besides, we would like to emphasize that the coupling calculation between the bound channels and open channels is indispensable. The study of the scattering process maybe an effective way to look for the genuine resonances. Published by the American Physical Society 2024
