摘要：
Using the one-boson-exchange model, we investigate the Lambda(c)(D) over bar (s)*, Sigma(c)(D) over bar (s)*, Sigma(c)*(D) over bar (s)*, Xi(c)(D) over bar*, Xi(c)'(D) over bar*, and Xi(c)*(D) over bar* 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 Xi(c)'(D) over bar* state with 0(1/2(-)) and the Xi(c)*(D) over bar* 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.
