Description

The NA48/2 experiment presents a final result of the charged kaon semileptonic decays form
factors measurement based on 4.28 million $K^\pm_{e3}$ and 2.91 million $K^\pm_{\mu 3}$ selected
decays collected in 2004. The result is competetive with other measurements in $K^\pm_{\mu 3}$
mode and has a smallest uncertainty for $K^\pm_{e3}$, that leads to the most precise
combined $K^\pm_{l3}$ result and allows to reduce the form factor uncertainty of $|V_{US}|$.
