Neutron-deuteron scattering (chiral potentials & regulator dependence)

The predictions for the differential cross section and the deuteron tensor analyzing power T$_{22}$ in nucleon-deuteron elastic scattering based on two chiral models of the nucleon-nucleon interaction are presented and compared with each other and with the data. The recent models at the fifth order of the chiral expansion from the Moscow(Idaho)-Salamanca group and from the Bochum group are used. At the energy of the incoming nucleon E=65 MeV both potentials yield similar data descriptions, however the differences between both models become more significant at E=200 MeV. At the latter energy the dependence of predictions on the used value of the regularization parameter becomes important. In particular, this cutoff dependence is much smaller in the case of the semilocally momentum space regularized potential from the Bochum group.
