Systematic analysis of the D-wave charmonium states with the QCD sum rules
Qi Xin, Zhi-Gang Wang
We systematically study the 1D charmonium spin-triplet (with the ) and spin-singlet (with the ) via the QCD sum rules in comparison wi…

Analysis of the hidden-charm pentaquark candidates in the mass spectrum via the QCD sum rules
Zhi-Gang Wang, Qi Xin
In this work, we distinguish the isospin for the first time and study the diquark-diquark-antiquark type pentaquark states with zero isospin via the QCD sum rules sys…
