Effective field theory for the two-nucleon system

Abstract

I discuss the dynamics of the two-nucleon system as obtained from a chiral nucleon-nucleon potential. This potential is based on a modified Weinberg power counting and contains chiral one- and two-pion exchange as well as four-nucleon contact interactions. The description of the S-waves is very precise. Higher partial waves are also well reproduced. We also find a good description of most of the deuteron properties.
