First observation of the rare decay mode $K^+ \to \mu^+ \nu_{\mu} \mu^+ \mu^-$ in the NA62 experiment at CERN SPS

The leptonic kaon decay $K^+ \to \mu^+ \nu_{\mu} \mu^+ \mu^-$ is among the clean modes to explore the flavour structure of the Standard Model. From the theoretical point of view, Chiral Perturbation Theory allows for an accurate calculation of the branching ratio and decay distributions. Experimenta...
