Abstract:
The three-nucleon system is the simplest testing ground in which the
quality of modern nucleon-nucleon interaction models can be probed
quantitatively by means of rigorous technique of solving the Faddeev
equations.
Experimental data show that for their proper description additional dynamics is needed, referred to as a genuine three-nucleon force. Recent precise measurements for the deuteron-proton breakup reaction showed significance of such subtle effects for the cross sections. Moreover, the results allowed to establish importance of other, only very recently introduced to the theoretical treatment, dynamical ingredients - the Coulomb interaction and relativistic effects.
