Abstract

The study of dibaryons has gained extensive attention both theoretically and experimentally since the confirmation of six-quark exotic [Formula: see text] dibaryon (with spin 3 and isospin 0) by recent COSY experiment. We ever proposed the chiral SU(3) quark model and predicted the binding energy of the [Formula: see text] system, in which the hidden-color channel was shown to play an important role in its structure. In this work, we further study the structure of [Formula: see text] dibaryon (with spin 0 and isospin [Formula: see text]) and strangeness [Formula: see text] under the chiral SU(3) quark model. The results show that hidden-color channel has an obvious influence on the binding energy of [Formula: see text] system.
