Possible strange hidden-charm pentaquarks from Σc(∗)D-s∗ and Ξc(′,∗) D-∗ interactions

Abstract

Using the one-boson-exchange model, we investigate the Λc D-s∗, Σ;c D-s∗, Ξc∗ D-s∗, Ξc D-∗, Ξc′ D-∗, 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 Ξc′ D-∗ 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.
