CP violation in $K\to {\mu }^{+}{\mu }^{-}$ with and without time dependence through a tagged analysis

Giancarlo D'Ambrosio, Avital Dery, Yuval Grossman +4

We point out that using current knowledge of $\mathcal{B}(K_L^0\to {\mu }^{+}{\mu }^{-})$ and $\mathcal{B}(K_L^0\to \gamma \gamma )$, one can extract short-distance information from the combined measurement of th…
