Abstract

Leading-order electromagnetic loop corrections to the one-pion-exchange potential are computed within the framework of chiral perturbation theory. These corrections generate an effective nucleon-nucleon potential, Vπγ, which supplements the sum of one-pion-exchange potential and the nucleon-nucleon Coulomb potential. This potential is charge dependent and its construction is demonstrated to be gauge invariant. The potential Vπγ has been included in the Nijmegen partial-wave analysis of n p data. A particular renormalization scheme is chosen that leads to a negligible change in the π±NN coupling constant and in the n p 1S0 scattering length and effective range.
