摘要 | The mixed propagator (MP) approach to rho-omega mixing is discussed. It is found that under the pole-approximation assumption the results of MP approach is not compatible both with the effective Lagrangian theory and with the experiment measurement criterion. To overcome these inconsistent, we propose a new MP approach in which the physical states of rho and omega are determined by the requirement of experimental measurement to meson resonance. In terms of this new MP approach, the EM pion form factor F-pi and form factors of rho(o) --> pi(o)gamma and of omega --> pi(o) gamma are derived. The results of F-pi are in good agreement with data. The form factor of rho(o) --> pi(o)gamma exhibits a hidden charge-asymmetry enhancement effect which agrees with the prediction of the effective Lagrangian theory. |
