摘要：

We calculate the branching ratio of omega --> pi(+)pi(-)gamma decay in a phenomenological framework in which the contributions of VMD, chiral loops, sigma-meson intermediate state amplitudes and the effects of omega-rho mixing axe considered. We conclude that the sigma-meson intermediate state amplitude-and omega-rho mixing make substantial contribution to the branching ratio.
