| 英文摘要 | The gluon and Goldstone boson induced tensor interaction effect on the dibaryon mass and the D-wavedecay width has been studied in the quark delocalization, color screening model. The effective S-D wave transition interactions induced by gluon and Goldstone boson exchanges decrease quickly as the increasing of the channel strangeness. The K and eta meson tenser contribution is negligible in this model. No six-quark state in the light flavor world can become a bound one by the help of these tensor interactions except the deuteron. The partial D-wave decay width of IJ(P) = (1)(/2) 2(divided by) NOmega state to spin 0,1 DeltaXi final state is 20.7 keV and 63.1 keV respectively. It is a very narrow dibaryon resonance and might be detected in the relativistic heavy ion reaction by the existing RHIC detectors through the reconstruction of the DeltaXi vertex mass and the future COMPAS detector at CERN and FAIR project in Germany. |
