The structure of a new dibaryon (ΩΩ)0+ is predicted in the framework of the chiral SU(3) quark model by solving a resonating group method (RGM) equation. The binding energy of this dibaryon is around 100 MeV, the mean squared root of the distance between two Ωs is 0.84 fm and the preliminary estimated mean life time is about 10−10sec. All these interesting properties, and also the two negative charge units it carries could make it to be easily identified experimentally in the heavy ion collision process.
