J/Ψ Λ Pentaquark Description of the P_(cc -s) (4459)^0

A first-order pentaquark model is utilized to model the P_(cc ?s) (4459)^0 resonance. The P_(cc ?s) (4459)^0 is modeled as a weakly bound J/Ψ meson plus Λ baryon molecular state. A first-order model predicts 1/2¯ and 3/2¯ spin and parity values that include the 3/2¯ experimental value. The predicted mass of 4448.1 MeV/c2 is within about 1% of the two candidate experimental values (4471.7 and 4458.8 MeV/c2).

Abstract

A first-order pentaquark model is utilized to model the P_(cc ?s) (4459)^0 resonance. The P_(cc ?s) (4459)^0 is modeled as a weakly bound J/Ψ meson plus Λ baryon molecular state. A first-order model predicts 1/2¯ and 3/2¯ spin and parity values that include the 3/2¯ experimental value. The predicted mass of 4448.1 MeV/c2 is within about 1% of the two candidate experimental values (4471.7 and 4458.8 MeV/c2).
