A search for hidden-charm pentaquark states decaying to a range of Σc anti-D and Λc+ anti-D final states, as well as doubly-charmed pentaquark states to Σc D and Λc+ 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 Λc+ baryon in the Λc+ → p K− π+ decay mode. The known pentaquark states are also investigated, and their signal yields are found to be consistent with zero in all cases.

Abstract

A search for hidden-charm pentaquark states decaying to a range of Σc anti-D and Λc+ anti-D final states, as well as doubly-charmed pentaquark states to Σc D and Λc+ 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 Λc+ baryon in the Λc+ → p K− π+ decay mode. The known pentaquark states are also investigated, and their signal yields are found to be consistent with zero in all cases.
