Abstract

CERN has hosted a sequence of high intensity kaon experiments over the last decades. The most recent of these experiments are NA48/2 (collected data in 2003-2004), NA62-RK (collected data in 2007) and NA62 (on-going, first data collected in 2015). Recent new results from these experiment are presented, including rare kaon decay measurements, searches for lepton number violation in kaon decays, and searches for exotic particles (heavy neutral leptons, dark photon, inflaton) in charged kaon and neutral pion decays. The status, prospects and physics programme of the on-going NA62 experiment are discussed.
