Description
Using the quark mass density- and temperature-dependent model, we have studied the properties of the dibaryon systems. The binding energy, radius and mean lifetime of (ΩΩ)0+ and (ΩΞ-) are given. We find the dibaryons (ΩΩ)0+ , (ΩΞ-), (ΩΞ0) are metastable at zero temperature, but the strong decay channel for (ΩΩ)0+ opens when the temperature becomes 126.8 MeV. It is shown that our results are in good agreement with those given by the chiral SU(3) quark model
