In this paper, we investigate the mass spectrum of the ground state hidden-charm tetraquark molecular states without strange, with strange and with hidden-strange via the QCD sum rules in a comprehensive way and revisit the assignments of the X, Y, Z states in the scenario of tetraquark molecular states consistently based on the QCD sum rules.

用 QCD 和规则分析 Hidden-charm Tetraquark 分子质谱

在本文中，我们通过 QCD 和规则全面研究了基态隐符四夸克分子态的无奇异、有奇异和有隐奇异的质谱，并重新审视了X,是,Z基于 QCD 和规则的四夸克分子状态中的状态一致。
