Possible Charmonium-like State
arXiv:1003.3721 · doi:10.1103/PhysRevD.81.105018
Abstract
We study the possible charmonium-like states with using the tetraquark interpolating currents with the QCD sum rules approach. The extracted masses are around 4.5 GeV for the charmonium-like states and 4.6 GeV for the 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 charmonium-like state.
