Analysis of the hidden-charm pentaquark candidates in the J/ψΩ mass spectrum via the QCD sum rules
Abstract
We explore the diquark-diquark-antiquark type ssscc̅ pentaquark states with the isospin-spin-parity IJP=01/2-, 03/2- and 05/2- 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 Ωb- → Pcsss-ϕ→ J/ψΩ- ϕ. Observations of the Pcsss states would shed light on the nature of exotic states and provide an excellent opportunity to distinguish the diquark-diquark-antiquark type pentaquark states from meson-baryon type molecular states.
