Possible JPC = 0-- Charmonium-like State
Abstract
We study the possible charmonium-like states with JPC=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.
