2-NUCLEON POTENTIAL FROM CHIRAL LAGRANGIANS

Chiral symmetry is consistently implemented in the two-nucleon problem at low-energy through the general effective chiral Lagrangian. The po tential is obtained up to a certain order in chiral perturbation theor y both in momentum and coordinate space. Results of a fit to scatterin g phase shifts and bound state data are presented, where satisfactory agreement is found for laboratory energies up to about 100 MeV.
