Dynamical calculation of \(d^\) mass and NN decay width in the quark delocalization, color screening model

The mass estimate of the \(d^* (IJ^P=03^+)\) dibaryon is improved by a dynamical calculation in the quark delocalization, color screening model. The partial decay width of \(d^*\) into an \(NN\) D-wave state is also obtained. The mass obtained is slightly larger than that obtained in adiabatic calcu...

Summary:The mass estimate of the \(d^* (IJ^P=03^+)\) dibaryon is improved by a dynamical calculation in the quark delocalization, color screening model. The partial decay width of \(d^*\) into an \(NN\) D-wave state is also obtained. The mass obtained is slightly larger than that obtained in adiabatic calculations, due to the anharmonicity of the effective potential between two \(\Delta\)'s. The value of the width obtained due to tensor one-gluon-exchange is about 5 MeV, comparable in magnitude to earlier results found using pion exchange.
