Nd elastic scattering as a tool to probe properties of 3N forces - art. no. 024007

Faddeev equations for elastic Nd scattering have been solved using modern N N forces combined with the Tucson-Melbourne two-pion exchange three-nucleon force, with a modification thereof closer to chiral symmetry and the Urban a IX three-nucleon force. Theoretical predictions for the differential cros s section and several spin observables using NN forces only and NN forces c ombined with three-nucleon force models are compared to each other and to t he existing data. A wide range of energies from 3 to 200 MeV is covered. Es pecially at the higher energies striking three-nucleon force effects are fo und, some of which are supported by the still rare set of data, some of whi ch are in conflict with data and thus very likely point to defects in those three-nucleon force models.
