Candidates of low-lying dibaryons with strangeness s⩽−5 in a symmetry analysis

By analyzing the symmetry and the intrinsic nodal surface of the six-quark systems with strangeness s⩽−5, it is shown that, besides the S-wave states [ΩΩ](0,0), [ΩΞ](1/2,1), [ΩΞ∗](1/2,0), the P-wave states {IJπ}={0 2−},{12 3−},{12 2−} may be the candidates of dibaryons. These states and the hidden color channel states with the same quantum numbers could be observed in experiments.
