385por Kozhuharov, Venelin“…The ratio of the leptonic charged kaon decays $R_K= \Gamma(K^{\pm} \to e^{\pm}\nu) / \Gamma(K^{\pm} \to \mu^{\pm}\nu)$ is sensitive to the structure of the week interactions and can be precisely calculated within the Standard Model. …”

This region can be probed by the further searches of NA62, DUNE, or SHiP experiments.…”
