    "abstract": "We study the self-energy amplitudes for the rho-omega meson system produced\nby an effective field theory model at the quark level characterized by a finite\nrange quark-quark interaction and an isospin breaking bare quark mass\ndifference $m_u - m_d$. Dynamical effects associated with confinement and\ndressing of quarks and the finite size of the produced $\\bar{q}q$ meson modes\nare treated. Parameters of this approach, previously constrained by soft pion\nphysics, are here supplemented in a minimal way to reproduce $m_\\omega$ and\n$g_{\\rho\\pi\\pi}$. Calculations are carried out up to the one pion loop level\nand the predictions for rho-omega mixing, mass splitting, the rho width and the\nsymmetry breaking omega-pi-pi coupling constant and form factor are presented.\nThe contribution of the direct $\\omega \\rightarrow \\pi\\pi$ process relative to\nthe $\\omega \\rightarrow \\rho \\rightarrow \\pi\\pi$ process is discussed within\nthis model.",
