Abstract：
We study possible exotic J^PC = 0^+- states using tetraquark interpolating currents with the QCD sum rule approach. The extracted masses are around 4.85 GeV for the charmonium-like states and 11.25 GeV for the bottomonium-like states. There is no working region for the light tetraquark currents, which implies that the light 0^+- state may not exist below 2 GeV.
