1. QCD sum rule studies of sss¯s¯ tetraquark states with JPC=1+- / Cui, Er-Liang ; Yang, Hui-Min ; Chen, Hua-Xing ; Chen, Wei ; et al
We apply the method of QCD sum rules to study the structure X newly observed by the BESIII Collaboration in the ϕη′ mass spectrum in 2.0–2.1 GeV region in the J/ψ→ϕηη′ decay. [...]

2. Revisiting hidden-charm pentaquarks from QCD sum rules Supported by National Natural Science Foundation of China (11722540, 11261130311), Fundamental Research Funds for the Central Universities, and Foundation for Young Talents in College of Anhui Province (gxyq2018103) / Xiang, Jia-Bing ; Chen, Hua-Xing ; Chen, Wei ; Li, Xiao-Bo ; et al
We revisit hidden-charm pentaquark states and using the method of QCD sum rules by requiring the pole contribution to be greater than or equal to 30% in order to better that the one-pole parametrization is valid [...]
