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 4.85 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.Physics, NuclearPhysics, Particles & FieldsSCI(E)中国科技核心期刊(ISTIC)中国科学引文数据库(CSCD)2ARTICLE3null3
