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 dynami cal calculation in the quark delocalization, color screening model. The par tial decay width of d* into an NN D-wave stare is also obtained. The mass o btained is slightly larger than that obtained in adiabatic calculations, du e to the anharmonicity of the effective potential between two Delta 's. The value of the width obtained due to tenser one-gluon exchange is about 5 Me V, comparable in magnitude to earlier results found using pion exchange. (C ) 2001 Elsevier Science B.V.
