    "abstract": "We consider charge-symmetry violations in the nucleon-nucleon force which\nresult from isospin-violating meson-baryon coupling constants. The vector\nmesons are assumed to couple to the nucleon\u0027s electromagnetic current, which we\ndecompose into isoscalar and isovector quark components. We compute these\ncurrents in the context of a constituent quark model. The isospin violations in\nthe meson-baryon couplings arise from the difference in the up and down\nconstituent quark masses. We show that class IV charge-symmetry-breaking\npotentials arise in the resulting $\\omega$ and $\\rho$ exchange contributions to\nthe $NN$ force. The magnitude of these contributions is consistent with that\nphenomenologically required by the measured difference of $n$ and $p$ analyzing\npowers in elastic $\\vec{n}-\\vec{p}$ scattering at 183 MeV.",
