A precision relation between Γ(K → μ + μ − )(t) and B K L → μ + μ − / B K L → γγ $$ \mathcal{B}\left({K}_L\to {\mu}^{+}{\mu}^{-}\right)/\mathcal{B}\left({K}_L\to \gamma \gamma \right) $$

A precision relation between Γ(K → μ + μ − )(t) and B K L → μ + μ − / B K L → γγ $$ \mathcal{B}\left({K}_L\to {\mu}^{+}{\mu}^{-}\right)/\mathcal{B}\left({K}_L\to \gamma \gamma \right) $$

Abstract We find that the phase appearing in the unitarity relation between B K L → μ + μ − $$ \mathcal{B}\left({K}_L\to {\mu}^{+}{\mu}^{-}\right) $$ and B K L → γγ $$ \mathcal{B}\left({K}_L\to \gamma \gamma \right) $$ is equal to the phase shift in the interference term of the time- dependent K → μ...
