Electromagnetic and Mass Difference Corrections in pion N Scattering
arXiv:nucl-th/0412114 · doi:10.1103/PhysRevC.72.065205
Abstract
Coulomb and mass difference corrections to low-energy pion-nucleon scattering are calculated and compared with previous work including potential models, dispersion relation methods and chiral perturbation theory calculations. Particular attention is paid to their role in testing isospin breaking.
