Search for prompt production of pentaquarks in charm hadron final states
A search for hidden-charm pentaquark states decaying to a range of Σ𝑐¯𝐷 and Λ+𝑐¯𝐷 final states, as well as doubly charmed pentaquark states to Σ𝑐𝐷 and Λ+𝑐𝐷, is made using samples of proton-proton collision data corresponding to an integrated luminosity of 5.7 fb−1 recorded by the LHCb detector a...

| 520 | |a A search for hidden-charm pentaquark states decaying to a range of Σ¯ and Λ+¯ final states, as well as doubly charmed pentaquark states to Σ and Λ+, 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 √ =13 TeV. Since no significant signals are found, upper limits are set on the pentaquark yields relative to that of the Λ+ baryon in the Λ+ →−+ decay mode. The known pentaquark states are also investigated, and their signal yields are found to be consistent with zero in all cases. | ||
