contents Within the framework of the one-boson-exchange model, we systematically perform a coupled channel analysis of the $P-$wave interactions between a charm baryon and light baryon, the involved channels include $Ξ_cN$, $Λ_cΣ$, $Ξ_c^{\prime}N$, $Σ_cΛ$, $Ξ_c^*N$, $Σ_c^*Λ$, $Σ_cΣ$, and $Σ_c^*Σ$. Our results can predict several possible molecular candidates, such as a $Ξ_c^{\prime}N$ molecule with $I(J^P)=0(1^-)$, $Ξ_c^{*}N$ molecules with $0(0^-, 1^-, 2^-)$, $Σ_cΣ$ molecules with $0(1^-)$ and $1(1^-)$, and $Σ_c^*Σ$ molecules with $0(0^-, 1^-, 2^-)$, and $1(2^-)$. The coupled channel effects significantly influence the formation of the $Σ_cΣ$ molecule with $1(1^-)$. Furthermore, we analyze the phase shifts for these coupled channel systems. Our analysis not only confirms the existence of the predicted molecules but also identifies potential resonant dibaryons, including a $Σ_cΣ$ shape-type resonance with $1(1^-)$, a $Σ_c^*Σ$ shape-type resonance with $1(0^-)$, a $Λ_cΣ/Σ_cΣ$ coupled Feshbach-type resonance with $1(1^-)$, and $Λ_cΣ/Σ_c^*Σ$ coupled Feshbach-type resonances with $1(0^-, 2^-)$.
