摘要：

We estimate the energy of the lowest charmonium and upsilon states with hybrid admixtures using the method of QCD Sum Rules. Our results show that the Psi'(2S) and Gamma(3S) states both have about a 50% admixture of hybrid and meson components. From this we find explanations of both the famous rho - pi puzzle for charmonium, and the unusual pattern of a decays that have been found in Gamma decays. Moreover, this picture can be used for predictions of heavy quark production with the octet model for RHIC.
