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 six-quark 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 [ΩΩ]_(0,0⁺), [ΩΩ]_(0,2^-), [Ξ* Ω]_(1/2,0⁺), [ΞΩ]_(1/2,1⁺), [Σ* Σ*]_(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.
