Zhi-Gang Wang

摘要:

本文用QCD求和规则研究了标量隐魅态和底四夸克态的质量谱。数值结果与基于准势方法的相对论性夸克模型的结果进行了比较。讨论了基于组分双夸克质量和自旋-自旋相互作用的组分双夸克模型的相关值。

英文摘要:

In this article, we study the mass spectrum of the scalar hidden charm and bottom tetraquark states with the QCD sum rules. The numerical results are compared with the corresponding ones from a relativistic quark model based on a quasipotential approach in QCD. The relevant values from the constituent diquark model based on the constituent diquark masses and the spin-spin interactions are also discussed.
