✦ Synopsis
The mass estimate of the d * (I J 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 ∆'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.
