Abstract
We consider a new three-nucleon force generated by the exchange of one pion in the presence of a correlation. The underlying irreducible diagram has been recently suggested by the authors as a possible candidate to explain the puzzle of the vector analyzing powers and for nucleon-deuteron scattering. Herein, we have calculated the elastic neutron-deuteron differential cross section, and below breakup threshold by accurately solving the Alt-Grassberger-Sandhas equations with realistic interactions. We have also studied how evolves below 30 MeV. The results indicate that this new 3 diagram provides one possible additional contribution, with the correct spin-isospin structure, for the explanation of the origin of this puzzle.
