英文摘要:
By analyzing the symmetry and the intrinsic nodal surface of the six-quark systems with strangeness s less than or equal to -5, it is shown that, besides the S-wave states [OhmOhm]((0,0)), [OhmXi]((1 /2.1)), [OhmXi*]((1 /2,0)), the P-wave states {I J(pi)} = {02(-)} = {02(-)}, {1/2 3(-)}, {1/2 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. (C) 2002 Elsevier Science B.V. All rights reserved.
