摘要: We consider charge-symmetry violations in the nucleon-nucleon force that result from isospin-violating meson-baryon coupling constants. The isospin arise difference up and down constituent quark masses. show a class IV charge-symmetry-breaking potential exists resulting {omega} exchange contribution to {ital NN} force. magnitude of this is consistent with phenomenologically required by measured n} p} analyzing powers elastic {rvec n}}{minus}{ital p}} scattering at 183 MeV.
