Selection Trigger for Rare Quark-Gluon Plasma Formation Events

We consider the experimental ratios of multistrange to strange antibaryon production and compare them to the standard Quark-Gluon String Model predictions. The significant differences between the experimental bar(Xi)+/bar(Lambda) and, especially, bar(Omega)+/bar(Lambda) values and model predictions can be interpreted as the signal of the existence of an additional source of multistrange antibaryon production. The possible connection of this additional source with Quark-Gluon Plasma (QGP) formation can turn the bar(Omega)+ production into a good QGP signature.
