Color Screening Effects on Hadronization at the Relativistic Heavy Ion Collider

The effects of color screening on the hadronization of a parton plasma into a hadron gas are examined at the energies of the relativistic heavy ion collider. It is found to have the tendency to prevent hadronization and therefore delaying the conversion of the partons into a hadron gas. Because of the continual expansion, the resulting hadron gas number densities are lower when screening is included. This should reduce the hadronic noise to genuine signals of the quark-gluon plasma. In this sense, color screening is favorable and should be included in numerical models. Hadronization is also shown to seriously disrupt parton equilibration and is yet another reason why full parton chemical equilibration should not be expected.
