D. R. Entem∗ and R. Machleidt† Department of Physics, University of Idaho, Moscow, ID 83844, USA (August 27, 2001) We present an accurate nucleon-nucleon (NN) potential based upon chiral effective Lagrangians. The model includes oneand two-pion exchange contributions up to chiral order three. We show that a quantitative fit of the NN D-wave phase shifts requires contact terms (which represent the short range force) of order four. Within this framework, the NN phase shifts below 300 MeV lab… CONTINUE READING
