- W1970992022 abstract "A specific interaction Lagrangian for an isotopic doublet boson is proposed which, to the first approximation in a perturbation expansion, can account for the lifetimes and branching ratios in K-π decays. Since parity is rigorously conserved in all K-π interactions, the K-meson is described as a parity doublet. The total Lagrangian is invariant under charge conjugation and time reflection. The strong interaction, of the form gSϕK†σ†χKχπ, is a scalar in isotopic space and is invariant under parity conjugation (in order to have scalar and pseudo-scalar K masses equal). The weak interaction, of the form gW(σ + α σ0†χKχπ, allows a change in total isotopic spin of 12 or 32. The final-state pions are considered to be in plane-wave states. The following dimensionless constants are obtained: gS = 1.6; gW = 5 × 10−8; α = −0.16. No account is taken of any of the K-decay modes involving neutrinos, nor of the production or scattering properties of the K-particles. The eight theoretically distinct K-mesons are reduced in number to the four actually distinguishable in K-decays." @default.
