Abstract

Recent results from the NA48/2 experiment are presented. The most precise measurement of the charged kaon semileptonic form factors has been obtained from 4.28 million K_e^±₃ and 2.91 million K_µ^±₃ events collected in 2004. A sample of 1663 events of the very rare decay K^± ? µ^±?e⁺e^- has been collected in the region Mee > 140 MeV/c² with negligible background. The measured model independent decay rate is in agreement with ChPT predictions. The branching ratio of the K^± ? p^±p⁰e⁺e^- decay, never observed so far, has been obtained from a sample of 5000 candidates, in agreement with ChPT predictions.
