• Branching ratios for the K^- capture by the nucleon are studied to investigate the validity of Gell-Mann's global symmetry. The following assumptions are made:1)Gell-Mann's global symmetry is valid, 2)K-meson is pseudoscalar, 3)mass differences among baryons can be neglected and 4)processes involving K-mesons are described by treating the M.S coupling as perturbations in the lowest order that gives the effect. Under these assumptions, the matrix element for the above mentioned processes are expressed in terms of the π-N scattering matrix elements for which experimental data can be used. The branching ratios, then, are compared with experimental results.
