| description | Abstract This work presents an analysis of a hidden charmed pentaquark candidate state with double strange quark in its quark content. The investigation is performed in two parts, which provide the mass prediction of the considered state and its partial decay widths for the $$P_{css}\rightarrow \Xi ^0 J/\psi $$ P css → Ξ 0 J / ψ and $$P_{css}\rightarrow \Xi _c^+ D_s^-$$ P css → Ξ c + D s - channels. For the analyses, two-point and three-point QCD sum rule methods are applied to get the mass and the widths, respectively. The mass for this candidate state is obtained as $$m_{P_{css}}=4600 \pm 155$$ m P css = 4600 ± 155 MeV with corresponding current coupling constant $$\lambda _{P_{css}}=(0.81 \pm 0.21)\times 10^{-3}$$ λ P css = ( 0.81 ± 0.21 ) × 10 - 3 GeV $$^6$$ 6 . These results are used in the analysis of the partial widths of this state for the decays $$P_{css}\rightarrow \Xi ^0 J/\psi $$ P css → Ξ 0 J / ψ and $$P_{css}\rightarrow \Xi _c^+ D_s^-$$ P css → Ξ c + D s - . From these decays, the total width is obtained as $$\Gamma = 12.29\pm 2.94 $$ Γ = 12.29 ± 2.94 MeV. These results may shed light on the future experimental searches in which such types of states are probed and may provide information to discriminate between such possible observations. |
