Abstract

A search for hidden-charm pentaquark states decaying to a range of ς_cD¯ and Λ_c⁺D¯ final states, as well as doubly charmed pentaquark states to ς_cD and Λ_c⁺D, is made using samples of proton-proton collision data corresponding to an integrated luminosity of 5.7 fb^-1 recorded by the LHCb detector at √s = 13 TeV. Since no significant signals are found, upper limits are set on the pentaquark yields relative to that of the Λ_c⁺ baryon in the Λ_c⁺→pK^-π⁺ decay mode. The known pentaquark states are also investigated, and their signal yields are found to be consistent with zero in all cases.
