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 ΞcN, ΛcΣ, Ξc^N, ΣcΛ, Ξc^*N, Σc^*Λ, ΣcΣ, and Σc^*Σ. Our results can predict several possible molecular candidates, such as a Ξc^N molecule with I(JP)=0(1⁻), Ξc*N molecules with 0(0⁻, 1⁻, 2⁻), ΣcΣ molecules with 0(1⁻) and 1(1⁻), and Σc^*Σ molecules with 0(0⁻, 1⁻, 2⁻), and 1(2⁻). The coupled channel effects significantly influence the formation of the ΣcΣ 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 ΣcΣ shape-type resonance with 1(1⁻), a Σc^*Σ shape-type resonance with 1(0⁻), a ΛcΣ/ΣcΣ coupled Feshbach-type resonance with 1(1⁻), and ΛcΣ/Σc^*Σ coupled Feshbach-type resonances with 1(0⁻, 2⁻).
