Towards heavy double-gluon hybrid mesons with exotic quantum numbers in QCD sum rules
Ding-Kun Lian, Qi-Nan Wang, Xu-Liang Chen +3
The double-gluon hybrid meson configuration was recently proposed and investigated within QCD sum rules. In this talk, we discuss the color structures of the double-gluon hybrid me…

Discontinuities of banana integrals in dispersion relation representation
Xu-Liang Chen, Peng-Fei Yang, Wei Chen
We derive the discontinuities of banana integrals using the dispersion relation iteratively. We find a series of identities between the parameterized discontinuities of banana inte…

Revisit the heavy quarkonium double-gluon hybrid mesons with exotic quantum numbers
Ding-Kun Lian, Qi-Nan Wang, Xu-Liang Chen +3
We revisit the masses of heavy quarkonium double-gluon hybrid mesons with exotic quantum numbers and in the framework of the QCD sum rules. Considering the…
