Abstract

The NA48/2 experiment at CERN collected a very large sample of charged kaon decays into multiple final states. These data allow measurements related to QCD. We obtained our final measurement of the charged kaon semileptonic decays form factors based on 4.28 million Ke3 and 2.91 million Kμ3 selected decays, with the smallest uncertainty for Ke3 and a competitive result for Kμ3 and leading to the most precise combined Kl3 result coming from the kaon sector that reduces the form factor uncertainty of/V_us/. The NA62 experiment at CERN SPS is designed to measure the branching ratio of the K⁺ → π⁺νν decay with 10% precision. K → πνν is one of the theoretically cleanest meson decay where to look for indirect effects of new physics complementary to LHC searches. NA62 took data in 2015-2017; the analysis of a partial data set allows to reach the Standard Model sensitivity. The status of the experiments will be presented.
