Selection Trigger for Rare Quark-Gluon Plasma Formation Events

Abstract

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 Ξ + /Λ and, especially, Ω + /Λ 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 Ω + production into a good QGP signature.

Multipomeron Model with Collective Effects for High-Energy Hadron Collisions

“…Further on, this subject of strangeness production in the hadronic collisions was the focus of many theoretical studies. In particular, they proposed the string fusion model [48,[58][59][60], which was widely used for the analysis of data on multi-particle production and explanation of enhanced yields of strange and multi-strange particles in heavy-ion collisions in [27][28][29][30]51,[61][62][63][64][65][66].…”
