Analysis of the pseudoscalar partner of the Y(4660) and related bound states
Abstract
In this article, we study the pseudoscalar bound state ηc'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 ηc'σ(400-1200), ηb'''f0(980) and ηb'''σ(400-1200), and make reasonable predictions for their masses.
