Description
We present a measurement of the charged kaon semileptonic form factors based on 4.3 million $K^\pm \rightarrow \pi^0 e^\pm \nu_e$ and 2.1 million $K^\pm \rightarrow \pi^0 \mu^\pm \nu_{\mu}$ 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.
