| 英文摘要 | The structure of a new dibaryon (Omega Omega)(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 100 MeV, the mean root square of the distance between two Omega s is 0.84 fm and the preliminary estimated mean lifetime is about two times longer than that of the free Omega. Ail 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. The production probability of this new dibaryon in 158A GeV Pb+Pb collision is estimated using the thermal model, which is of the order of 10(-6) to 10(-5) per event. And it is expected, that with the increase of temperature, the production rate will also be increased. |
