The influence of gluon and Goldstone boson induced tensor interactions on the dibaryon masses and D-wave decay widths has been studied in the quark delocalization, color screening model. The effective S\penalty1000-\hskip0ptD wave transition interactions induced by gluon and Goldstone boson exchanges decrease rapidly with increasing strangeness of the channel. The tensor contribution of K and \ensuremathη mesons is negligible in this model. There is no six-quark state in the light flavor world studied so far that can become bound by means of these tensor interactions besides the deuteron. The partial D-wave decay widths of the IJp=(1∕2)2+N\ensuremathΩ state to spin 0 and 1 \ensuremathΛ\ensuremathΞ final states are 12.0 and 21.9 keV, respectively. This is a very narrow dibaryon resonance that might be detectable in those production reactions with rich high strangeness particles through the reconstruction of the vertex mass of the decay product \ensuremathΛ\ensuremathΞ by existing detectors at RHIC and COMPASS at CERN or at JHF in Japan and FAIR in Germany in the future.
