Dynamical calculation of d∗ mass and NN decay width in the quark delocalization, color screening model Original Research Article

The mass estimate of the d∗(IJP=03+) dibaryon is improved by a dynamical calculation in the quark delocalization, color screening model. The partial decay width of d∗ into an NND-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 Δʹs. 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.
