Possible J~（PC）=0~（＋-） exotic states

We study possible exotic J~（PC）=0~＋- states using tetraquark interpolating currents with the QCD sum rule approach. The extracted masses are around 4.85GeV for the charmonium-like states and 11.25 GeV for the bottomonium-like states. There is no working region for the light tetraquark currents, whic...

Zusammenfassung:We study possible exotic J~（PC）=0~＋- states using tetraquark interpolating currents with the QCD sum rule approach. The extracted masses are around 4.85GeV 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 2GeV.
