Description
We consider the experimental ratios of multistrange to strange antibaryon production as a function of centrality. The predictions of the well-stablished Quark-Gluon String Model fail to describe the experimental data on overline(Xi)+/overline(Lambda) and, especially, \overline(Omega)+/\overline(Lambda), for the case of heavy-ion collisions at high centralities. This significant disagreement between experimental data and model predictions could be interpreted as the signal of Quark-Gluon Plasma (QGP) formation, making of the overline(Omega)+ production a possible QGP signature.
