    "abstract": "It is shown that the relative sign between the $NN\\omega$ and $\\pi\\rho\\omega$\ncoupling constants can be determined most sensitively from $\\omega$ production\nprocesses in $NN$ collisions. Recent data on these reactions clearly favor the\nsign of the $\\pi\\rho\\omega$ coupling constant which is opposite to that\ninferred from studies of the photoproduction reaction in combination with the\nvector meson dominance assumption and used by many authors. Implication of this\nfinding in the description of other reactions is discussed.",
