Rare Kaon Decay to Missing Energy: Implications of the NA62 Result for a $Z^{\prime }$ Model

Téssio B. de Melo, Sergey Kovalenko, Farinaldo S. Queiroz +2

Meson decays offer a good opportunity to probe new physics. The rare kaon decay $K^{+}\to {\pi }^{+}\nu \bar{\nu }$ is one of the cleanest of them and, for this reason, is rather sensitiv…
