论文摘要
具有陌生内容的五夸克人的存在，其中一个是强子物理学最新几年的主要发现。这些状态中的大多数可以理解为Hadronic分子，并在基于从载体中膜交换相互作用获得的单位化的介子 - 巴里元振幅的模型中进行了预测。与较早的陈述相反，我们表明该模型还可以预测具有双重陌生性的五夸克人的存在，约为4500 MEV和4600 MEV，它们是通过非常具体且独特的机制生成的，它是由两个最重的中孔巴里昂国家之间的强耦合引起的吸引力。
The existence of pentaquarks with strangeness content zero and one are major discoveries of the latest years in hadron physics. Most of these states can be understood as hadronic molecules and were predicted prior to their discovery within a model based on unitarized meson-baryon amplitudes obtained from vector meson exchange interactions. Contrary to earlier statements, we show this model to also predict the existence of pentaquarks with double strangeness, at about 4500 MeV and 4600 MeV, which are generated in a very specific and unique mechanism, via an attraction induced by a strong coupling between the two heaviest meson-baryon states.
