The structure of a new dibaryon(&OHgr;&OHgr;)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 &OHgr;s is 0.84 fm and the preliminary estimated mean life time is about10−10 sec.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. ©2001 American Institute of Physics.
