Possible strange hidden-charm pentaquarks from ∑c(*)Ds* and Ξc(',*)* interactions

  • Using the one-boson-exchange model, we investigate the ΛcDs*, ∑cDs*, ∑c*Ds*, ΞcD*, Ξ'cD*, and Ξc*D* interactions by considering the one-eta-exchange and/or one-pion-exchange contributions. We further predict the existence of hidden-charm molecular pentaquarks. Promising candidates for hidden-charm molecular pentaquarks include a Ξ'cD* state with 0((1/2)-) and the Ξc*D* states with 0((1/2)-) and 0((3/2)-). Experimental searches for these predicted hidden-charm molecular pentaquarks are an interesting future research topic for experiments like LHCb.

Abstract: Using the one-boson-exchange model, we investigate the ΛcDs*, ∑cDs*, ∑c*Ds*, ΞcD*, Ξ'cD*, and Ξc*D* interactions by considering the one-eta-exchange and/or one-pion-exchange contributions. We further predict the existence of hidden-charm molecular pentaquarks. Promising candidates for hidden-charm molecular pentaquarks include a Ξ'cD* state with 0((1/2)-) and the Ξc*D* states with 0((1/2)-) and 0((3/2)-). Experimental searches for these predicted hidden-charm molecular pentaquarks are an interesting future research topic for experiments like LHCb.
