New results on kaon decays from NA48

New measurements of $K_{L}$ and $K_{S}$ decays from the NA48 experiment are presented. From data taken in the year 2001, the value of the $K_{e3}$ charge asymmetry has been determined to $\delta_{L}(e) = (3.317 \pm 0.070_{stat} \pm 0.072_{syst}) \times 10^{-3}$. From a special high-intensity $K_{S}$ run period performed in 2000, NA48 has found a limit of $1.4 \times 10^{-6}$ on the $K_{S} \to 3 \pi^{0}$ branching ratio and measured the parameter $\eta_{000}$. The same data sample also leads to the first observation of the rare decay $K_{S} \to \pi^{0}\gamma \gamma$. All results are still preliminary.
