Analysis of the fully-heavy pentaquark states via the QCD sum rules

Abstract

In the article, we investigate the diquark-diquark-antiquark type fully-heavy pentaquark states with the spin-parity $J^P={\frac{1}{2}}^{-}$ via the QCD sum rules, and obtain the masses $M_{cccc\bar{c}}=7.93\pm 0.15\mathrm{GeV}$ and $M_{bbbb\bar{b}}=23.91\pm 0.15\mathrm{GeV}$. We can search for the fully-heavy pentaquark states in the $J/\psi {\Omega }_{ccc}$ and ${\rm Y}{\Omega }_{bbb}$ invariant mass spectrum in the future.
