Abstract

We present a measurement of the charged kaon semileptonic form factors based on 4.3 million K± ? p0e±?e and 2.9 million K± ? p0µ±?µ decays collected by the NA48/2 experiment. The single results for the semi-electronic and semi-muonic channel have better and similar precision, respectively, than previous measurements. The combination of both channels yields the most precise measurement of the form factors of semileptonic kaon decays.
