  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.
