Low-lying dibaryon states in a symmetry analysis

The dibaryon states as six-quark clusters of exotic QCD states are investigated in this talk. With the inherent nodal surface structure analysis, the wave functions of the sixquark clusters (in another word, the dibaryons) are classified. The contribution of the hidden color channels are discussed. The quantum numbers of the low-lying dibaryon states are obtained. The States [OmegaOmega]((0,0+)), [OmegaOmega]((0,2)(-)()), [*Omega]((1/2,0)(+) ()) , = [KOmega](1/2,1(+)), [Sigma*Sigma*1](0,4(-)) and the hidden color channel states with the same quantum numbers are proposed to be the candidates of dibaryons, which may be observed in experiments.
