Two-nucleon potential from chiral Lagrangians

Abstract

Chiral symmetry is consistently implemented in the two-nucleon problem at low-energy through the general effective chiral Lagrangian. The potential is obtained up to a certain order in chiral perturbation theory both in momentum and coordinate space. Results of a fit to scattering phase shifts and bound state data are presented, where satisfactory agreement is found for laboratory energies up to about 100 MeV. \textcopyright{} 1996 The American Physical Society.
