Abstract

During 2003 and 2004, the NA48/2 experiment has collected at the CERN SPS the world largest amount of charged kaon decays, with the main goal to search for direct CP violation in the decay of K± into three pions. From a dedicated data sample collected in 2004, the analysis of K ±e3 and K±μ3 decay data has allowed precise measurements of the form factors in various parametrizations. Later, in 2007-2008, using the same detector but a modified beam and trigger logic, the NA62 experiment has taken data to measure the ratio of K → ev and K → v leptonic decays and has obtained a sub-percent measurement of the ratio RK = Γ(Ke2)/Γ(K μ2). © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.
