1203.5199 (Meng-Lin Du et al.)

Possible $J^{PC} = 0^{+-}$ Exotic State    [PDF]

Meng-Lin Du, Wei Chen, Xiao-Lin Chen, Shi-Lin Zhu
We study the possible exotic states with $J^{PC} = 0^{+-}$ using the 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 bottomomium-like states. There is no working region for the light tetraquark currents, which implies the light $0^{+-}$ state may not exist below 2 GeV.
