Nd Scattering Observables Derived from the Quark-Model Baryon-Baryon Interaction

Abstract

We solve the nd scattering in the Faddeev formalism, employing the NN sector of the quark‐model baryon‐baryon interaction fss2. The energy‐dependence of the NN interaction, inherent to the (3q)‐(3q) resonating‐group formulation, is eliminated by the standard off‐shell transformation utilizing the 1/N factor, where N is the normalization kernel for the (3q)‐(3q) system. This procedure yields an extra nonlocality, whose effect is very important to reproduce all the scattering observables below En≤65 MeV. The different off‐shell properties from the standard meson‐exchange potentials, related to the non‐locality of the quark‐exchange kernel, yields appreciable effects to the differential cross sections and polarization observables of the nd elastic scattering, which are usually attributed to the specific properties of three‐body forces.
