Influence of tensor interactions on masses and decay widths of dibaryons
发表期刊PHYSICAL REVIEW C
关键词Color-screening Model Extended Quark-delocalization
摘要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-D wave transition interactions induced by gluon and Goldstone boson exchanges decrease rapidly with increasing strangeness of the channel. The tensor contribution of K and eta 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 IJ(p)=(1/2)2(+)NOmega state to spin 0 and 1 LambdaXi 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 LambdaXi by existing detectors at RHIC and COMPASS at CERN or at JHF in Japan and FAIR in Germany in the future.
