The logarithms of $Γ[K0(t)→f]$ (dashed line) and of $Γ[K0¯(t)→f]$ (dashed-dotted line) plotted against the time t measured in units $τS$⁠. We have used the values of $ΓL/ΓS,Δm/ΓS,$ and $δ$ in eqns (8.2)–(8.3) and (8.17). Also, $∣ηf∣=δ/2$ and $ϕf=43.49°$ are the (approximate) values relevant for the two-pion decay modes. For an appropriate scaling of the logarithms we have taken $∣〈f∣T∣KS〉∣2=106$⁠. For $t<6τS$ both curves approximately follow the simple exponential decay of $KS$⁠; for $t>18τS$ they both approximate the exponential decay of $KL$⁠. The interference between $KL→ππ$ and $KS→ππ$ is maximal for $t∼9−15τS$⁠, and has opposite sign in the decays of $K0(t)$ and of $K0¯(t)$⁠.
