Ξ_c D ?, Λ ηc, and Λ J/Ψ Pentaquark Descriptions of Structures Near 4465 Mev/c2

A first-order pentaquark models is utilized to model the  and Pcs(4472) resonances as weakly coupled meson and baryon clusters.  , Λ ηc, and Λ J/Ψ pentaquark configurations are used in the analysis. A first-order model predicts a 1/2¯ ( , Λ ηc,) or 1/2¯ and 3/2¯ (Λ J/Ψ) assignment for these three pentaquark configurations. An analysis by Wang et al. predicts the Pcs(4459) [Pcs(4472)] has a 3/2¯ (1/2¯) assignment. Given the accuracy of the first-order model, all assumed configurations are representative of the experimental mass in the vicinity of 4465 Mev/c2.
