Estimations of $\bar{\Omega}^+/\Omega^-$ at RHIC from a QGP Model with Diquarks

Abstract

Assuming that axial-vector and scalar diquarks exist in the Quark-Gluon Plasma near the critical temporature $T_c$, baryons can be produced from quark-diquark interactions. In RHIC conditions ($\sqrt{s_{NN}} = 130GeV$ and $200GeV$), the ratio $\bar{\Omega}^+/\Omega^-$ may be larger than 1, based on the concept that QGP with diquarks would exist. This unusual result might be a helpful evidence for QGP existing in RHIC.Comment: 6 pages, 1 figure. accepted by J.Phys.
