Possible J^(PC) = 0⁻⁻ Charmonium-like State

We study the possible charmonium-like states with $J^{PC}=0^{--}, 0^{-+}$ using the tetraquark interpolating currents with the QCD sum rules approach. The extracted masses are around 4.5 GeV for the $0^{--}$ charmonium-like states and 4.6 GeV for the $0^{-+}$ charmonium-like states while their bottomonium-like analogues lie around 10.6 GeV. We also discuss the possible decay, production and the experiment search of the $0^{--}$ charmonium-like state.
