Systematic analysis of the transition form factors of to -wave charmonia and corresponding semileptonic decays
Jie Lu, Dian-Yong Chen, Guo-Liang Yu +1
In this article, the vector, axial vector and tensor form factors of to -wave charmonia () and are analyzed within the framework of three-point QCD…
Tetraquark states in the quark model
Wei-Lin Wu, Yan-Ke Chen, Yao Ma +2
We perform systematical investigations of heavy flavor tetraquark systems, including fully heavy (), doubly heavy (), and…
QCD sum rule study of topped mesons within heavy quark effective theory
Shu-Wei Zhang, Xuan Luo, Hui-Min Yang +1
Motivated by the recent CMS observation of a near-threshold enhancement in top quark pair production, we investigate a novel class of hadronic systems containing a single top quark…
Analysis of the hadronic molecules , , and their bottom analogs with QCD sum rules
Ze Zhou, Guo-Liang Yu, Zhi-Gang Wang +1
In this work, we construct the color-singlet-color-singlet type currents to study the masses and pole residues of charm-strange tetraquark states and their bottom analogs with $J^P…
Analysis of the strong vertices and in QCD sum rules
Jie Lu, Dian-Yong Chen, Guo-Liang Yu +2
In this article, we firstly analyze the mass and pole residue of negative parity nucleon within the two-point QCD sum rules. Basing on these results, we continuously st…
The reaction and the and contributions
Wen-Tao Lyu, Man-Yu Duan, De-Min Li +3
Motivated by the recent LHCb Collaboration analysis, we have investigated the process by considering the contributions from the resonances and $K…
