Heavy Quarks & Leptons Kaon Physics

Recent results and prospects for precision tests of the Standard Model in kaon decay in flight experiments at CERN are presented. A measurement of the ratio of leptonic decay rates of the charged Kaon at a 0.4% precision constrains the parameter space of new physics models with, for example, an extended Higgs sector. Searches for neutrino mass states and the dark photon in the ~100 MeV/c^2 mass range based on samples collected in 2003-2007 are in progress and prospects will be discussed. The NA62 experiment starting in 2014 will search for a range of lepton number and lepton flavour violating decays of the charged kaon and the neutral pion at improved sensitivities down to ~10^{-12}, probing new physics scenarios involving, for example, heavy Majorana neutrinos. The foreseen NA62 L0 trigger strategy for rare decays will be discussed.
