Abstract

A measurement of the form factors of charged kaon semileptonic decays is presented, based on 4.4 × 106K± → π0e±νe (Ke3 ±) and 2.3 × 106K± → π0μ±νμ (Kμ3 ±) decays collected in 2004 by the NA48/2 experiment. The results are obtained with improved precision as compared to earlier measurements. The combination of measurements in the Ke3 ± and Kμ3 ± modes is also presented. © 2018, The Author(s).
