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

Abstract

In this article, we study the pseudoscalar bound state ${\eta }_c^{\prime }{f}_0(980)$ (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 ${\eta }_c^{\prime }\sigma (400-1200)$, ${\eta }_b^{\prime \prime \prime }{f}_0(980)$ and ${\eta }_b^{\prime \prime \prime }\sigma (400-1200)$, and make reasonable predictions for their masses.
