Abstract

We estimate differential rapidity cross sections for J/ΨJ/\Psi and Υ(1S)\Upsilon(1S) production via Cu-Cu and Au-Au collisions at RHIC, and the relative probabilities of Ψ(2S)\Psi'(2S) to J/ΨJ/\Psi production via p-p collisions using our recent theory of mixed heavy quark hybrids, in which the Ψ(2S)\Psi'(2S) mesons have approximately equal normal qqˉq\bar{q} and hybrid qqˉgq\bar{q}g components. We also estimate the relative probabilities of Ψ(2S)\Psi'(2S) to J/ΨJ/\Psi production via Cu-Cu and Au-Au collisions, which will be measured in future RHIC experiments. We also review production ratios of Υ(2S)\Upsilon(2S) and Υ(3S)\Upsilon(3S) to Υ(1S)\Upsilon(1S) in comparison to recent experimental results.This is an extension of our recent work on p-p collisions for possible tests of the production of Quark-Gluon Plasma via A-A collisions at BNL-RHIC.
