✦ Synopsis

We apply the quark delocalization and color screening model to nucleon-baryon scattering. A semi-quantitative fit to N-N, N-Λ and N-Σ phase shifts and scattering cross sections is obtained without invoking meson exchange. Quarks delocalize reasonably in all of the different flavor channels to induce effective nucleon-baryon interactions with both a repulsive core and with an intermediate range attraction in the cases expected.

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 calculation
