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

The effective SD wave transition interactions led by gluon and Goldstone boson invent decrease as the increasing of the channel strangeness. The Kand η meson tensor contribution is negligible in this model. No six-quark state in the light flavor world can become abound one by the help of these tensor interactions except the deuteron.
