Predicting possible molecular states of nucleons with Ξ c , Ξ c , and Ξ c

In the framework of a one-boson-exchange model, we carry out a comprehensive investigation of the Ξ c N / Λ c Σ / Ξ c ′ N / Σ c Λ / Ξ c * N / Σ c * Λ / Σ c Σ / Σ c * Σ interactions. We consider the S − D -wave mixing effects and the coupled-channel effects to derive the relevant effective potentials. Our results can predict several possible charm-strange deuteronlike Ξ c ( ′ , * ) N hexaquarks, the Ξ c ′ N molecules with I ( I P ) = 0 ( 0 + ) , 0 ( 1 + ) , 1 ( 1 + ) , the Ξ c * N molecules with 0 ( 1 + ) , 0 ( 2 + ) , 1 ( 2 + ) , and the coupled Ξ c N / Ξ c ′ N / Ξ c * N / Σ c Σ / Σ c * Σ molecule with 0 ( 1 + ) . We expect the experiments to search for our predictions of the Ξ c ( ′ , * ) N bound states.
