论文摘要
随着高能量物理实验的发展，已经观察到了大量的Hadronic部门中的外来状态。为了对Tetraquark和Pentaquark候选人的性质进行一些见解，一种组成夸克模型以及高斯扩展方法已被系统地用于实地和复杂的研究。我们在此回顾了双重和全面的四夸克人，还审查了隐藏式的，-bottom和双重迷人的Pentaquarks。在我们的方法中，有几种实验观察到的异国黑质体得到了很好的再现。此外，提出了它们可能的综合性，并相应地分析了其他特性，例如它们的衰减宽度和频谱中的一般模式。此外，我们还报告了研究中的四夸克和五夸克部门中的实验尚未看到的一些预测。
With the development of high energy physics experiments, a large amount of exotic states in the hadronic sector have been observed. In order to shed some insights on the nature of the tetraquark and pentaquark candidates, a constituent quark model, along with the gaussian expansion method, has been employed systematically in the real- and complex-range investigations. We review herein the double- and full-heavy tetraquarks, but also the hidden-charm, -bottom and doubly charmed pentaquarks. Several experimentally observed exotic hadrons are well reproduced within our approach; moreover, their possible compositeness are suggested and other properties analyzed accordingly such as their decay widths and general patterns in the spectrum. Besides, we report also some predictions not yet seen by experiment within the studied tetraquark and pentaquark sectors.
