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 $[\Omega \Omega {]}_{(0,0^{+})}$, $[\Omega \Omega {]}_{(0,2^{-})}$, $[{\Xi }^{\ast }\Omega {]}_{(1/2,0^{+})}$, $[{\Sigma }^{\ast }{\Sigma }^{\ast }{]}_{(0,4^{-})}$ 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.
