We solve the nd scattering in the Faddeev formalism, employing the NN sector of the quarkmodel 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-model baryonbaryon interaction, 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.
