The branching ratio of the decay of the hyperons, the ratios of the mean lifetimes of the various hyperons, and the ratio of the lifetimes of hyperons to K/sup +/ -mesons are calculated by using the universal Fermi weak interaction proposed by Feynman and Gell-Mann and the strong interaction proposed by Salam. The perturbation theory is used with a cut off in the region of large momentum. By using the coupling constants of the strong interaction given by Warner and choosing suitable values for the other two coupling constants remaining to be fixed, most of the calculated results agree fairly well with experiments. The worst result differs from the experimental values at most by a factor of 2. The theoretical values of the branching ratios of K/sup +/-decay derived from this set of coupling constants show better agreement with experiment than previous results. Calculations show that the universal Fermi weak interaction of V-A type gives a satisfactory explanation of the decay phenomena of K-mesons and hyperons. It is also evident from the calculation that these deeays must be regarded as phenomena brought about by the joint action of strong and weak interactions and that there exist two classes of strong interactions: the "very strong" and the "medium strong." The results favor the assumption that the LAMBDA and SIGMA have the same parity. They also show that of the 4 terms of the strong interaction Hamiltonian given by Salam involving the Kmeson, at least two terms involve a gamma /sub 5/ matrix. (auth)
