Analysis of the pseudoscalar partner of the Y(4660) and related bound states

Regular Article - Theoretical Physics

Abstract

In this article, we study the pseudoscalar bound state ηcf0(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 ηcσ(400−1200), ηb'''f0(980) and ηb'''σ(400−1200), and make reasonable predictions for their masses.
