Interaction current in strangeness-violating decays

Abstract

The consequences of the hypothesis that the current of strongly interacting particles contributing to strangeness-violating decays has the transformation properties of an isospinor are investigated. The six processes K⁺→π⁰+μ⁺+ν, K⁻→ π⁰+μ⁻+ν̅, K₁⁰→π⁺+μ⁻+ν̅,K₁⁰→π⁻+μ⁺+ν, K₂⁰→π⁺+μ⁻+ν̅, K₂⁰→π⁻+μ⁺+ν would then have the same rates, angular correlations, spectra, etc., and likewise for electron modes. This prediction is compared with available experimental data. The evidence from the nonlepton decays is briefly examined.
