Light double-gluon hybrid states with the exotic quantum numbers $J^{PC}=1^{-+}$ and $3^{-+}$

Niu Su, Wei-Han Tan, Hua-Xing Chen +2

We apply the QCD sum rule method to study the double-gluon hybrid states with the quark-gluon contents $\bar{q}qgg$ ($q=u/d$) and $\bar{s}sgg$. We construct twenty-eight double-g…
