Funded by SCOAP3.A candidate triple strange pentaquark state, Pcsss, is investigated through its strong decay channel Pcsss→ω-J/ψ. To calculate the relevant strong coupling constants, two possible interpolating currents with spin-parity JP=12- are used. Though the chosen currents for the state under consideration have spin-parity quantum numbers JP=12-, they couple to both the positive and negative parity states simultaneously and the corresponding decay widths are obtained for both parities. These widths are obtained as Γ(Pcsss→J/ψω-)=201.4±82.5 MeV for the negative and Γ(Pcsss→J/ψω-)=316.4±107.8 MeV for the positive parity state when the first current is used. For the second current, we obtain Γ(Pcsss→J/ψω-)=252.5±116.7 MeV for the negative and Γ(Pcsss→J/ψω-)=361.1±98.4 MeV for the positive parity state. These results may provide insights into future experimental observations of such candidate states and help to distinguish and fix their properties.
