Can the newly reported Pcs(4459) be a strange hidden-charm Ξc(D)over-bar* molecular pentaquark?

Stimulated by the P-cs(459) eported by the LHCb collaboration, we perform a single Xi(c)<(Dover bar>*channel and a coupled Xi(c)<(Dover bar>*/Xi(')c<(Dover bar>*/Xi(c)<(Dover bar>*/Xi(c)<(Dover bar>*c (D) over bar =Xi(')c (D) over bar* =. c (D)over bar> channel analysis by using a one-boson-exchange model. Our results indicate that the newly Pcs o4459THORN cannot be a pure.cD molecular state, but a coupled Xi(')c<(Dover bar>* =.0 c D =. c D bound state with (IoJP) = (o3/(2)-), where the. (D) over bar * and (D) over bar> components are dominant. Meanwhile, we find the interactions from the. Xi(c)<(Dover bar>* system with 0(1/2-), the. c D system with 1(3/2-()), and the Xi(')c<(Dover bar>* system with 1(1/2-) are strongly attractive, where one can expect possible strange hidden-charm molecular or resonant structures near these thresholds with the assigned quantum numbers.(D) over bar

Automated summary

The research results show that the new Pcs o4459THORN may not be a pure.cD molecular state, but a bound state with a coupled structure of Xi(')c <(Dover bar>* =.0 c D =. c D, indicating possible strange hidden-charm molecular or resonant structures near certain thresholds.
