    "abstract": "The momentum-dependence of the $\\rho^0$-$\\omega$ mixing contribution to\ncharge-symmetry breaking (CSB) in the nucleon-nucleon interaction is compared\nin a variety of models. We focus in particular on the role that the structure\nof the quark propagator plays in the predicted behaviour of the\n$\\rho^0$-$\\omega$ mixing amplitude. We present new results for a confining\n(entire) quark propagator and for typical propagators arising from explicit\nnumerical solutions of quark Dyson-Schwinger equations. We compare these to\nhadronic and free quark calculations. The implications for our current\nunderstanding of CSB experiments is discussed.",
