Abstract:

The Σ+ - Σ- mass difference and the electromagnetic correction on the Δ I = 1/2 law for the non-leptonic hyperon and K-meson decays are discussed, based on the assumption of charge independence for the strong interactions. Simple calculation, for the two phenomena, reveals the difficulty that we need larger electromagnetic effects than those discussed. Various approximate conservation laws in the isotopic spin space and their implications for the understanding of the non-leptonic decays are likewise discussed.
