Kaon physics at the CERN-SPS

The NA48/2 and NA62 collaborations report on recent results, current status, and prospects of kaon physics at the CERN-SPS. The NA62 collaborations aims to measure the decay K±→ π±νν̄ with an uncertainty of 10% or better. The NA62 detector and preliminary results from a pilot run in 2014 are presented. In addition, recent results of the NA48/2 collaboration are reported. A search for Dark Photons has been performed in π0 decays via the kaon decays K±→ π±π0 and K±π0μ±ν. No dark photon signal was observed and new upper limits on the mixing parameter ϵ2 and the dark photon mass were computed. We also report the first observation of the kaon decay K±→ π±π0e+e−.
