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 follows: Γ(Pcsss→J/ψΩ−)=201.4±76.7 MeV for the negative and Γ(˜Pcsss→J/ψΩ−)=316.4±100.3 MeV for the positive parity state when the first current is used. For the second current, we obtain Γ(Pcsss→J/ψΩ−)=252.5±108.6 MeV for the negative and Γ(˜Pcsss→J/ψΩ−)=361.1±88.2 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.
