Results and prospects for $K\to \pi \nu \bar{\nu }$ at NA62 and KOTO

Abstract

The $K\to \pi \nu \bar{\nu }$ ultra-rare decays are precisely computed in the Standard Model (SM) and are ideal probes for physics beyond the SM. The NA62 experiment at the CERN SPS is designed to measure the charged channel with a precision of 10\%. The statistics collected in 2016 allows to reach the SM sensitivity. The KOTO experiment at J-PARC aims at reaching the SM sensitivity before performing a measurement with $\sim 100$ signal events. The NA62 preliminary result for the charged channel is presented, together with the current experimental status of the neutral channel and their prospects for the coming years.
