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.
