- 論文の詳細を見る
The form factors in the K_<l3> decay modes are evaluated by means of perturbation theory and N/D method. In our treatment we regard the baryon-antibaryon closed loop as the elementary process, and the s-wave K-π scattering near at the threshold as an enhancement for it. The results are compared with the experimental data, especially, in connection with the ratio ξ=f_-/f_+. Though our numerical results are incapable of explaining the large value of the ratio ξ shown by the present experiments, there is a good reason to believe that it is important to treat the baryon-antibaryon intermediate state in a more suitable way.
