New developments in the study of few-nucleon systems

The current status of the theoretical studies of the few-nucleon systems is reviewed. We show that in the study of the A = 3,4 bound states the different methods have reached a great precision even when realistic Hamiltonians including two- and three-body interactions are considered. The description of scattering observables can be achieved with a similar accuracy, as shown by recent comparisons performed by several groups. The availability of bound and continuum states allows for interesting tests of new models of the nuclear interaction and for important studies of electro-weak reactions.
