Abstract
First results of rigorous 3N Faddeev calculations including realistic NN and 3N forces (3NF) are presented. We compare the theoretical analyzing power ${\mathit{A}}_{\mathit{y}}$ in elastic Nd scattering at ${\mathit{E}}_{\mathrm{lab}}^{\mathit{N}}$=3.0 MeV to recently measured nd data. As 3NF we take the Tucson-Melbourne 2\ensuremath{\pi}-exchange model. We study its dependence on the \ensuremath{\pi}N form-factor cutoff parameter and also the interplay of three realistic NN forces with that 3NF. The discrepancy between theory and experiment, present for NN forces only, turns out to be aggravated when including that 3NF. Further efforts to be taken are indicated.
