In this paper, a new type of hybrid state, which consists of two valence quarks and two valence antiquarks together with a valence gluon, the gluonic tetraquark states, are investigated. Twenty-four currents of the the gluonic hidden-charm tetraquark states in ![$$[\bar{3}_c]_{c q}\otimes [8_c]_{G}\otimes [3_c]_{\bar{c} \bar{q^\prime }}$$](/articles/epja/abs/2025/01/10050_2024_Article_1475/10050_2024_Article_1475_tex_eq1.png)
configuration are constructed, and their mass spectrum are evaluated in the framework of QCD sum rules with quantum numbers of 
, 
, 
, and 
. The nonperturbative contributions up to dimension 8 are taken into account. The results indicate that there may be exist 14 gluonic hidden-charm tetraquark states, and their corresponding hidden-bottom partners are also evaluated. The possible production and decay modes of the gluonic tetraquark states are analyzed, which are hopefully measurable in BESIII, BELLEII, PANDA, Super-B, and LHCb experiments.
