Scientific paper

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 +- 0.070(stat) +- 0.072 (syst)) x 10^-3. From a special high-intensity K_S run period performed in 2000, NA48 has found a limit of 1.4 x 10^-6 on the K_S -> 3 pi0 branching ratio and measured the parameter eta_000. The same data sample also leads to the first observation of the rare decay K_S -> pi0 gamma gamma. All results are still preliminary.
