Review of Charmonium and Bottomonium Quark State Production via Relativistic Heavy Ion Collisions

摘要

This is a review of the production of heavy quark states via relativistic heavy ion collisions in RHIC. The heavy quarks here are c , charm quark, and b , bottom quark. The states are charmonium meson states Ψ ( n S ) , with n = 1,2 and upsilon meson states Υ ( m S ) , with m = 1,2,3. Quantum Chromodynamics (QCD) sum rules were used to derive the result that the Ψ ( 2 S ) and Υ ( 3 S ) are mixed hybrid states, which increase their production cross sections. We also review the Ψ ( n S ) and Υ ( m S ) production cross sections via Cu-Cu and Au-Au collisions, which are very important for this review of the production of heavy quark states in RHIC. The possible detection of the Quark Gluon Plasma (QGP) is also reviewed.
