Emergence of charm-strange dibaryons with negative parity via baryon-baryon interactions

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 ${\mathrm{\Xi }}_{c}N$, ${\mathrm{\Lambda }}_c\mathrm{\Sigma }$, ${\mathrm{\Xi }}_c^{\mathrm{\prime }}N$, ${\mathrm{\Sigma }}_c\mathrm{\Lambda }$, ${\mathrm{\Xi }}_c^{\ast }N$, ${\mathrm{\Sigma }}_c^{\ast }\mathrm{\Lambda }$, ${\mathrm{\Sigma }}_c\mathrm{\Sigma }$, and ${\mathrm{\Sigma }}_c^{\ast }\mathrm{\Sigma }$. Our results can predict several possible molecular candidates, such as a ${\mathrm{\Xi }}_c^{\mathrm{\prime }}N$ molecule with $I(J^P)=0(1^{-})$, ${\mathrm{\Xi }}_c^{\ast }N$ molecules with $0(0^{-},1^{-},2^{-})$, ${\mathrm{\Sigma }}_c\mathrm{\Sigma }$ molecules with $0(1^{-})$ and $1(1^{-})$, and ${\mathrm{\Sigma }}_c^{\ast }\mathrm{\Sigma }$ molecules with $0(0^{-},1^{-},2^{-})$, and $1(2^{-})$. The coupled channel effects significantly influence the formation of the ${\mathrm{\Sigma }}_c\mathrm{\Sigma }$ 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 ${\mathrm{\Sigma }}_c\mathrm{\Sigma }$ shape-type resonance with $1(1^{-})$, a ${\mathrm{\Sigma }}_c^{\ast }\mathrm{\Sigma }$ shape-type resonance with $1(0^{-})$, a ${\mathrm{\Lambda }}_c\mathrm{\Sigma }\mathrm{/}{\mathrm{\Sigma }}_c\mathrm{\Sigma }$ coupled Feshbach-type resonance with $1(1^{-})$, and ${\mathrm{\Lambda }}_c\mathrm{\Sigma }\mathrm{/}{\mathrm{\Sigma }}_c^{\ast }\mathrm{\Sigma }$ coupled Feshbach-type resonances with $1(0^{-},2^{-})$.
