Analysis of the hidden-charm pentaquark candidates in the $J\mathrm{/}\psi \mathrm{\Omega }$ mass spectrum via the QCD sum rules

We explore the diquark-diquark-antiquark type $sssc\bar{c}$ pentaquark states with the isospin-spin-parity $I{J}^P=0{\frac{1}{2}}^{-}$, $0{\frac{3}{2}}^{-}$ and $0{\frac{5}{2}}^{-}$ via the QCD sum rules in details and obtain the ground state mass spectrum. And we suggest to hunt for these exotic states in the exclusive decay ${\mathrm{\Omega }}_b^{-}\to P_{csss}^{-}\phi \to J\mathrm{/}\psi {\mathrm{\Omega }}^{-}\phi$. Observations of the $P_{csss}$ states would shed light on the nature of exotic states and provide an excellent opportunity to distinguish the diquark-diquark-antiquark type pentaquark states and meson-baryon type molecular states.
