On the Importance of Rare Kaon Decays: A Snowmass 2021 White Paper

Jason Aebischer, Andrzej J. Buras, Jacky Kumar

We stress the importance of precise measurements of rare decays $K^{+}\to {\pi }^{+}\nu \bar{\nu }$, $K_L\to {\pi }^0\nu \bar{\nu }$, $K_{L,S}\to {\mu }^{+}{\mu }^{-}$ and $K_{L,S}\to {\pi }^0{\ell }^{+}{\ell }^{-}$ for the sea…
