Abstract

The chiral next-to-next-to-next-to leading order nuclear forces¹⁻³ are used to obtain predictions for spin observables in elastic nucleon-deuteron scattering at E=13 MeV. The three-nucleon force is taken into account with all its complexity, including the short-range part and relativistic corrections. Presented examples of the polarization observables for elastic nucleon-deuteron scattering show visible contributions from these new structures in the three-nucleon potential which emerge for the first time at the next-to-next-to-next-to leading order. However, our results suggest that some modifications of the currently used model of the nuclear forces are necessary.
