稀有夸克-胶子等离子体形成事件的选择触发

Selection Trigger for Rare Quark-Gluon Plasma Formation Events

G. H. Arakelyan, C. Merino, Yu. M. Shabelski

摘要:

我们考虑了多奇异反重子产生的实验比率,并将其与标准夸克-胶子弦模型的预测进行了比较。实验bar(Xi)+/bar(Lambda),特别是bar(Omega)+/bar(Lambda)值与模型预测值之间的显著差异可以解释为存在多奇异反重子产生的额外来源的信号。这个额外的源与夸克-胶子等离子体(QGP)形成的可能联系可以将棒(Omega)+的产生转化为良好的QGP特征。

英文摘要:

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.
