Abstract

In this article, we study the pseudoscalar bound state η_c'f₀(980) (irrespective of the hadro-charmonium and the molecular state) with the QCD sum rules. Considering the SU(3) symmetry of the light flavor quarks and the heavy quark symmetry, we also study the bound states η_c'σ(400-1200), η_b'''f₀(980) and η_b'''σ(400-1200), and make reasonable predictions for their masses.
