摘要：

In this study, we evaluated the mass spectra of the prospective 0(--) hidden-charm and hidden-bottom tetraquark states in molecular configuration via QCD sum rules. In our calculation, the nonperturbative condensate contributions are considered up to dimension eight in operator product expansion. It is found that there could exist 4 possible 0(--) hidden-charm tetraquark states with masses (4.68 +/- 0.07), (4.22 +/- 0.09), (4.53 +/- 0.09), and (4.26 +/- 0.13) GeV. Their corresponding hidden-bottom partners are found lying at (11.04 +/- 0.10), (10.71 +/- 0.12), (11.09 +/- 0.10), and (11.82 +/- 0.14) GeV, respectively. The possible tetraquark decay modes were analyzed, which are expected to be measured in BESIII, BELLEII, and LHCb experiments.
