摘要：

In this work, we study the 1(--) double-gluon charmonium ((c) over bar ggc) and bottomonium ((b) over bar ggb) hybrids in terms of QCD sum rules. We find that the mass of eggc hybrid lies in M-Hc = 5.33-5.90 GeV, while in the bottom sector the mass of (b) over bar ggb hybrid may be situated in M-Hb = 11.20-11.68 GeV. The contributions up to dimension eight at leading order of alpha(s) (LO) in the operator product expansion are taken into account in the calculation. The double-gluon charmonium hybrid meson predicted in this work can decay into a pair of charmed mesons or a pair of charmed mesons together with a light meson. Especially, we propose to search for (c) over bar ggc hybrid with I-G(J(PC)) = 0(-) (1(--)) in their decay channels D (D) over bar /D*(D) over bar /D*(D) over bar* with P wave and D*(D) over bar*pi/D*(D) over bar*eta/D (D) over bar rho/D (D) over bar omega with S wave, which may be accessible in Belle II, PANDA, Super-B, GlueX, and LHCb experiments.
