The $X(3872)\\rightarrow J/\\psi \\pi \\gamma$ is dominated by the $\\omega$ meson. As for the $X(3872)\\rightarrow J/\\psi \\pi\\pi \\gamma$, the contributions of the cascade decays through the $\\rho$ and $\\omega$ mesons are strongly suppressed with respect to the diagrams which proceed either through the $\\psi(2S)$ or the three body decay of $\\rho$.
