The transition matrix for K^--P reaction is discussed. The scattering length for K^--P interaction is obtained in terms of the coupling constants between K^--P, π-Σ and π-Λ channels. The relation between the branching ratio of Y^* and Σ/Λ ratio at threshold is derived. The large imaginary part of I=0 scattering length is discussed under the assumption π-Σ P_<1/2> resonance. The coupling constant of Fujii-Sakurai's vector meson is tentatively determined.
