Note on the Strangeness Conserving β-Decays of Σ±-hyperons Σ±→ Λ+e±±ν

Strangeness conserving BETA -decays of the SIGMA hyperons are discussed. Their partial decay rates are known to be smaller than those predicted by universality. It is noticed that this fact is more consistent with the Goldhaber picture of hyperons than other possibilities. (auth) kawa coupling theory about the interaction of bosons and baryons are also investignted. It is shown that the coupling constant of pion to nucleon is correctly given independent of the details of our method. Comments on the properties of nuclear forces in the inner region are given.
