Low-lying S-wave and P-wave Dibaryons in a Nodal Structure Analysis

Abstract

The dibaryon states as six-quark clusters of exotic QCD states are investigated in this paper. 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 $[ΩΩ]_{(0,0^{+})}$, $[ΩΩ]_{(0,2^{-})}$, $[Ξ^{*}Ω]_{(1/2,0^{+})}$, $[Σ^{*}Σ^{*}]_{(0,4^{-})}$ 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.
