Abstract：
The structure of a new dibaryon (ΩΩ)₀⁺ is studied and predicted in the framework of the chiral SU(3) quark model by solving a resonating group method equation.The binding energy of this dibaryon is around 100MeV,the mean root square of the distance between two Ωs is 0.84fm and the preliminary estimated mean lifetime is about two times longer than that of the Ω.All these interesting properties and also the two negative charge units it carried could make it be easily identified experimentally in the heavy-ion collision process.
